HSMBJSAC5.0 thru HSMBJSAC50
500 WATT LOW CAPACITANCE TRANSIENT VOLTAGE SUPPRESSOR
DESCRIPTION
The HSMBJSAC transient voltage suppressor (TVS) series rated at 500 Watts provides an added rectifier element as shown in Figure 4 to achieve low capacitance in applications for data or signal lines. The low capacitance rating of less than 30 pF may be used for protecting higher frequency applications in inductive switching environments or electrical systems involving secondary lightning effects per IEC61000-4-5 as well as RTCA/DO-160D or ARINC 429 for airborne avionics. If bidirectional protection is needed, two HSMBJSAC devices in anti-parallel configuration are required as shown in Figure 6. With their very fast response time, they also provide ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4 respectively.

FEATURES
• Unidirectional low-capacitance TVS series (for bidirectional see Figure 6)
• Suppresses transient up to 500 Watts Peak Pulse Power @ 10/1000 µs
• Improved performance in low capacitance of 30 pF
• Economical small plastic surface mount with robust axial subassembly package
• Options for screening in accordance with MIL-PRF19500 for JAN, JANTX, JANTXV, and JANS are also available by adding MQ, MX, MV, or MSP prefixes respectively to part number, e.g. MXSAC5.0, MVSAC18, etc.
• Also available in surface mount with SMAJ prefix for part numbers (ex. SMAJSAC5.0)
• UL94V-0 Flammability Classification
APPLICATIONS / BENEFITS
• Low Capacitance for data-line protection to 70 MHz
• Protection for aircraft fast data rate lines per select level waveforms in RTCA/DO-160D & ARINC 429
• ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4 respectively
• Secondary lightning protection per IEC61000-4-5 with 42 Ohms source impedance: Class 1: HSMBJSAC5.0 to HSMBJSAC50 Class 2: HSMBJSAC5.0 to HSMBJSAC45 Class 3: HSMBJSAC5.0 to HSMBJSAC22 Class 4: HSMBJSAC5.0 to HSMBJSAC10
• Secondary lightning protection per IEC61000-4-5 with 12 Ohms source impedance Class 1: HSMBJSAC5.0 to HSMBJSAC26 Class 2: HSMBJSAC5.0 to HSMBJSAC15 Class 3: HSMBJSAC5.0 to HSMBJSAC7.0
MAXIMUM RATINGS
• Peak Pulse Power Dissipation at 25oC: 500 Watts @ 10/1000 µs with repetition rate of 0.01% or less*
• Steady State Power Dissipation* at TL = +75oC: 2.5 Watts.
• Clamping Speed (0 volts to V(BR) Min.) less than 5 nanoseconds.
• Operating and Storage Temperature: -65oC to +150oC.
MECHANICAL AND PACKAGING
• CASE: Void Free Transfer Molded Thermosetting Plastic (see DO-214AA dimensions and notes)
• FINISH: All External Surfaces Are Corrosion Resistant and Leads Solderable
• POLARITY: Cathode (TVS) Marked with Band • MARKING: Part number without HSMBJ prefix (ie. SAC5.0)
• WEIGHT: 0.1 Grams (Approx.)
* TVS devices are not typically used for dc power dissipation and are instead operated < VWM (rated standoff voltage) except for transients that briefly drive the device into avalanche breakdown (VBR to VC region) of the TVS element. Also see Figures 5 and 6 for further protection details in rated peak pulse power for unidirectional and bidirectional configurations respectively.
