1N6358 – 1N6372 or MPT-10 – MPT-45C
Available
1500 Watt Low Clamping Factor Transient Voltage Suppressor
DESCRIPTION
This Transient Voltage Suppressor (TVS) series for 1N6358 through 1N6372 are JEDEC registered selections for both unidirectional and bidirectional devices. The 1N6358 through 1N6364 are unidirectional and the 1N6366 through 1N6372 are bidirectional where they all provide a very low specified clamping factor for minimal clamping voltages (VC) above their respective breakdown voltages (VBR) as specified herein. They are most often used in protecting sensitive components from inductive switching transients or induced secondary lightning effects as found in lower surge levels of IEC61000-4-5. They are also very successful in protecting airborne avionics and electrical systems. Since their response time is virtually instantaneous, they can also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

Notes: 1. When mounted on FR4 PC board with 4 mm2 copper pads (1 oz) and track width 1 mm, length 25 mm.
2. At 10/1000 µs with repetition rate of 0.01% or less (see figures 1, 2, & 4).
3. At 3/8 inch (10 mm) from body (see derating in figure 5). TVS devices are not typically used for dc
power dissipation and are instead operated at or less than their rated standoff voltage (VWM) except for transients that briefly drive the device into avalanche breakdown (VBR to VC region).

SYMBOLS & DEFINITIONS Definition
Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition. Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25 oC. Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the peak pulse current in a one millisecond time interval. The peak pulse voltage is the combination of voltage rise due to bot.
