Surface Mount TRANSZORB - SMC (DO-214AB) - Unidirectional/Bidirectional Transient Voltage Suppressors - SMCJ5.0A thru SMCJ188CA

Oct 12, 2026

Surface Mount TRANSZORB transient voltage suppressors in the SMC (DO-214AB) package cover unidirectional and bidirectional protection devices from SMCJ5.0A through SMCJ188CA. The specification lists primary characteristics such as VBR range 6.40 V to 231 V, VWM range 5.0 V to 188 V, and peak pulse power PPPM of 1500 W with PD of 6.5 W. It defines electrical characteristics including breakdown voltage, test current, stand-off voltage, reverse leakage, peak surge current, clamping voltage, and temperature coefficient, plus mechanical data, polarity rules, and maximum ratings (TJ/TSTG -55 to +150 °C).

FAQs

What is the operating and storage temperature range for these SMC TRANSZORB devices?

The operating junction temperature and storage temperature range is -55 to +150 °C.

How do you identify bidirectional devices in this series?

For bidirectional devices, use the CA suffix (for example, SMCJ188CA). Electrical characteristics apply in both directions.

What are the typical key electrical limits listed in the document?

Key limits include VBR (6.40 V to 231 V), VWM (5.0 V to 188 V), PPPM of 1500 W, PD of 6.5 W, and TJ max of 150 °C, along with surge current and clamping voltage values per device.
