Product details
Overview
1.5SMC100AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge 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 (IPPM), and 1500 W peak pulse power capability with a 10/1000 μs waveform. It is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive applications.
For engineers reviewing the 1.5SMC100AHM3/H datasheet, 1.5SMC100AHM3/H pinout, 1.5SMC100AHM3/H application, or 1.5SMC100AHM3/H equivalent, this device serves as a robust, low-profile clamping solution for protecting MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in automotive and industrial systems.
Technical Context
The 1.5SMC100AHM3/H operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and low incremental surge resistance. Its breakdown voltage (VBR) is specified at 95–105 V (min/max) under 1 mA test current, ensuring precise overvoltage triggering.
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with RθJA = 75 °C/W and RθJL = 15 °C/W. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, supporting lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 95–105 V at IT = 1 mA - Tight tolerance ensures consistent turn-on threshold across production lots. |
| VC (Clamping Voltage) | 137 V at IPPM = 10.9 A - Limits transient voltage seen by downstream circuitry during 10/1000 μs surge events. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy surges without failure when mounted on 8.0 mm × 8.0 mm copper pads. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss. |
| TJ max. | +150 °C - Enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | SMC (DO-214AB) - Low-profile surface-mount package optimized for automated placement and thermal dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Same VWM (85.5 V) and VC (137 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients (IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 line surges. | Select when board space is critical and surge energy is ≤400 W; not recommended for automotive load dump. |
| 1.5KE100A | Through-hole TO-204AA (DO-41); identical electrical specs but larger footprint and manual assembly requirement. | Used where legacy through-hole design or higher mechanical robustness is prioritized over SMT automation. | Choose for prototyping or low-volume industrial controls where reworkability and thermal mass outweigh SMT efficiency. |
Compared with SMAJ100A and 1.5KE100A, the 1.5SMC100AHM3/H uniquely combines AEC-Q101 qualification, halogen-free compliance, 1500 W surge handling, and SMC package automation compatibility-making it the preferred choice for volume automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC100AHM3/H under a 10/1000 μs surge?
The 1.5SMC100AHM3/H has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM) under a 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 defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the 1.5SMC100AHM3/H suitable for automotive applications?
Yes, the 1.5SMC100AHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly rated for operation from –65 °C to +150 °C and validated for thermal cycling, mechanical shock, and humidity resistance required in engine bay and chassis-mounted modules.
What does the "HM3" suffix mean in 1.5SMC100AHM3/H?
The "HM3" suffix in 1.5SMC100AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates 7-inch tape-and-reel packaging (850 units/reel), while "M3" confirms compliance with JESD201 Class 2 whisker resistance and lead-free reflow compatibility up to 260 °C peak.
How does the 1.5SMC100AHM3/H compare to bidirectional TVS diodes like 1.5SMC100CA?
The 1.5SMC100AHM3/H is unidirectional and intended for DC rail protection where polarity is fixed; it offers lower leakage (<1 μA) and tighter VBR tolerance than its bidirectional counterpart 1.5SMC100CA. The latter supports AC or floating signal lines but exhibits higher ID and asymmetric clamping behavior in each direction.
What is the thermal resistance of the 1.5SMC100AHM3/H?
The 1.5SMC100AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W, measured under standard JEDEC test conditions (25 °C ambient, minimum pad layout). These values guide heatsinking decisions and derating calculations above 25 °C ambient.
