Product details
Overview
1.5SMC100AHM3/I 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 standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the 1.5SMC100AHM3/I datasheet, 1.5SMC100AHM3/I pinout, 1.5SMC100AHM3/I application, or 1.5SMC100AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package dimensions, thermal resistance data, and real-world design implications for surge immunity validation and PCB layout planning.
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its 10.9 A peak pulse current rating (IPPM) is specified under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and it maintains clamping performance across -65 °C to +150 °C operating junction temperature range.
The device exhibits a 0.106 %/°C temperature coefficient of breakdown voltage (VBR) and achieves 75 °C/W junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads. It meets JESD201 Class 2 whisker resistance and MSL Level 1 per J-STD-020, supporting lead-free reflow up to 260 °C peak.
Key Specifications

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 | Lower peak pulse power (600 W), same VWM/VC ratings, SMB (DO-214AA) package - 30% smaller footprint but higher RθJA (110 °C/W). | Best suited for space-constrained consumer electronics where 600 W surge immunity suffices; not rated for AEC-Q101. | Select when board area is critical and automotive qualification is unnecessary; verify thermal margin with reduced copper pad area. |
| 1.5KE100A | Through-hole TO-204AE (DO-41) package, identical electrical specs, but no AEC-Q101 qualification and higher mounting height. | Used in legacy industrial power supplies where manual assembly or wave soldering is preferred; incompatible with automated SMT lines. | Choose only for repair/refurbishment of existing through-hole designs; avoid for new automotive or high-reliability SMT production. |
Compared with SMBJ100A and 1.5KE100A, the 1.5SMC100AHM3/I uniquely combines AEC-Q101 qualification, 1500 W surge rating, and SMC package thermal performance - making it the only option qualified for new automotive electronics requiring both high-power transient immunity and surface-mount manufacturability.

FAQ
What is the clamping voltage of the 1.5SMC100AHM3/I under a 10/1000 μs surge?
The 1.5SMC100AHM3/I has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 1.5SMC100AHM3/I qualified for automotive applications?
Yes, the 1.5SMC100AHM3/I is AEC-Q101 qualified - confirmed by Vishay's documentation for the HM3 suffix variant. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making the 1.5SMC100AHM3/I suitable for under-hood and chassis-mounted automotive electronics where reliability under thermal and electrical stress is mandatory.
What does the "HM3" suffix indicate in 1.5SMC100AHM3/I?
The "HM3" suffix in 1.5SMC100AHM3/I denotes a halogen-free, RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads. The "I" indicates packaging in 13-inch tape-and-reel format (3500 units per reel), while the "H" would denote 7-inch reels. This suffix confirms compliance with automotive material and process requirements beyond commercial-grade variants.
How does the thermal resistance of the 1.5SMC100AHM3/I affect PCB layout?
The 1.5SMC100AHM3/I has a typical RθJA of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads. To maintain junction temperature below 150 °C during repetitive surges, PCB layout must allocate sufficient copper area and consider thermal vias - reducing pad size increases RθJA, risking thermal runaway during sustained transient activity.
Can the 1.5SMC100AHM3/I be used in bidirectional configurations?
No, the 1.5SMC100AHM3/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the 1.5SMC100CA variant. Using the 1.5SMC100AHM3/I in reverse-biased configurations risks permanent damage due to lack of symmetrical breakdown characteristics.
