Product details
Overview
1.5SMC100A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V breakdown voltage (VBR = 95–105 V), 137 V maximum clamping voltage at 10.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supplies, industrial motor controllers, and telecom interface protection.
For engineers reviewing the 1.5SMC100A-M3/57T datasheet, 1.5SMC100A-M3/57T pinout, 1.5SMC100A-M3/57T application, or 1.5SMC100A-M3/57T equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, 85.5 V stand-off voltage, <1 µA reverse leakage at VWM, and AEC-Q101 qualification readiness via M3 suffix.
Technical Context
This TVS diode operates as a clamping device triggered by transient overvoltage events exceeding its reverse stand-off voltage of 85.5 V. Its glass-passivated junction enables fast response time (<1.0 ns) and low incremental surge resistance, ensuring effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The 1.5SMC100A-M3/57T is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), supports operation from −65 °C to +150 °C, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-reliability automated SMT assembly without moisture sensitivity concerns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 | Lower peak power (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Best suited for space-constrained consumer electronics with lower-energy transients | Select when board area is critical and surge energy does not exceed 600 W capability |
| 1.5KE100A | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Used in legacy designs or prototyping where manual soldering or socketing is acceptable | Choose only for repair, replacement, or non-SMT production environments |
Compared with SMBJ100A-E3/52 and 1.5KE100A, the 1.5SMC100A-M3/57T delivers 2.5× higher surge power in an SMT-compatible package with superior thermal performance (RθJL = 15 °C/W), making it optimal for automotive and industrial applications demanding both robustness and manufacturability.

FAQ
What is the maximum clamping voltage of the 1.5SMC100A-M3/57T under a 10/1000 µs transient?
The 1.5SMC100A-M3/57T has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 10.9 A with a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1.5SMC100A-M3/57T suitable for automotive applications?
Yes, the 1.5SMC100A-M3/57T is halogen-free and RoHS-compliant per its M3 suffix, and belongs to the AEC-Q101-qualified 1.5SMC family. While the base M3 version is commercial-grade, ordering variants such as 1.5SMC100AHM3_A/H provides full AEC-Q101 qualification - making the 1.5SMC100A-M3/57T a direct path to automotive-compliant design when specified with appropriate suffixes.
What is the reverse stand-off voltage (VWM) of the 1.5SMC100A-M3/57T?
The reverse stand-off voltage (VWM) of the 1.5SMC100A-M3/57T is 85.5 V. This is the maximum DC or continuous reverse working voltage that can be applied without causing significant leakage current - specified at ≤1.0 µA. It ensures the device remains non-conductive during normal operation while allowing sufficient margin below the 95–105 V breakdown range.
Does the 1.5SMC100A-M3/57T have polarity marking, and how is it identified?
Yes, the 1.5SMC100A-M3/57T is unidirectional and features a cathode band marking on the SMC (DO-214AB) package body. The banded end corresponds to the cathode terminal, which must be connected toward the higher-potential side of the protected line. No marking is used on bidirectional variants, but the 1.5SMC100A-M3/57T explicitly uses the "A" suffix denoting unidirectional configuration.
What is the thermal resistance from junction to leads (RθJL) for the 1.5SMC100A-M3/57T?
The thermal resistance from junction to leads (RθJL) for the 1.5SMC100A-M3/57T is 15 °C/W, as specified in the Vishay datasheet. This low value reflects efficient heat transfer from the silicon die through the internal lead frame - supporting reliable operation at elevated ambient temperatures and enabling higher sustained power dissipation compared to alternatives with higher RθJL.
