Product details
Overview
1.5SMC100AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 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 (PPPM) with a 10/1000 μs waveform - deployed for robust overvoltage protection on DC power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the 1.5SMC100AHM3_A/H datasheet, 1.5SMC100AHM3_A/H pinout, 1.5SMC100AHM3_A/H application, or 1.5SMC100AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to deliver fast response time (<1 ns) and stable breakdown behavior under repetitive transient stress. Its clamping performance is characterized by a 137 V VC at 10.9 A IPPM, with thermal resistance RθJA of 75 °C/W and RθJL of 15 °C/W.
The 1.5SMC100AHM3_A/H exhibits a breakdown voltage (VBR) range of 95.0–105 V at 1 mA test current, reverse leakage ID ≤1.0 μA at 85.5 V VWM, and a temperature coefficient of VBR at +0.106 %/°C - confirming predictable voltage drift across automotive-grade operating temperatures (−65 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 85.5 V - maximum continuous reverse working voltage before clamping initiates; defines safe DC operating margin. |
| VBR (Breakdown) | 95.0–105 V at 1 mA - precise avalanche onset range ensuring reliable triggering without premature conduction. |
| VC (Clamping) | 137 V at 10.9 A IPPM - peak voltage seen by protected circuit during worst-case 10/1000 μs surge; limits stress on downstream ICs. |
| PPPM | 1500 W - peak transient energy absorption capability with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| TJ max | +150 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 0.320" × 0.246" footprint; optimized for thermal dissipation on 8 mm × 8 mm copper pads. |
| AEC-Q101 | Qualified - certified for automotive electronics per stress-test requirements including HTOL, TCT, and ESD HBM ≥8 kV. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection point for unidirectional TVS | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode | Low-side reference terminal | Typically tied to system ground or common return path; completes clamping loop during transient events. |
Key Features

| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units against load dump surges up to 120 V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp transients before they reach LDO regulators or MCU VDD pins. Use Value: Limits clamped voltage to 137 V while absorbing 1500 W pulses - preventing latch-up or permanent damage to 16-bit MCUs rated for 140 V absolute max. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in factory-floor pressure sensors exposed to relay switching noise. IC Role / Device Role / Timing Role: TVS mounted across sensor output and ground to suppress inductive kickback from nearby solenoid drivers. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC front-ends experience overvoltage beyond their 36 V rating. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding PoE-powered network switches from lightning-induced surges entering via 48 V DC input ports. IC Role / Device Role / Timing Role: Primary-stage TVS on main DC bus, upstream of DC/DC converters and Ethernet PHYs. Use Value: Withstands 10/1000 μs surges up to 1500 W while maintaining <1.0 μA leakage at 85.5 V - preserving standby power budget. |
Use Scenario: Suppressing commutation spikes generated by brushed DC motors in smart washing machines during direction reversal. IC Role / Device Role / Timing Role: TVS connected across motor terminals to divert inductive energy back into the supply rail or shunt to ground. Use Value: 137 V clamping prevents MOSFET drain-source breakdown in half-bridge drivers rated for 150 V VDSS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Lower PPPM (400 W), SMA package (smaller thermal mass), VBR 95–105 V same range, but lower IPPM (32.4 A → 10.9 A for 1.5SMC100AHM3_A/H). | Not AEC-Q101 qualified; suited for commercial-grade consumer products only. | Select SMAJ100A only if space-constrained layouts and reduced surge severity allow lower power rating. |
| 1.5KE100A | Through-hole DO-201 package, identical VWM/VBR/VC specs, but higher RθJA (100 °C/W vs. 75 °C/W) and no AEC-Q101 or halogen-free certification. | Limited to non-automotive, non-SMT production; incompatible with automated assembly lines. | Choose 1.5KE100A only for prototyping or legacy through-hole designs where rework tolerance outweighs production efficiency. |
Compared with SMAJ100A and 1.5KE100A, the 1.5SMC100AHM3_A/H delivers superior thermal performance, automotive qualification, and SMT manufacturability - making it the sole option meeting both IATF 16949 production requirements and 1500 W surge immunity in compact form factor.

FAQ
What is the maximum clamping voltage of the 1.5SMC100AHM3_A/H under a 10/1000 μs surge?
The 1.5SMC100AHM3_A/H 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 Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC100AHM3_A/H AEC-Q101 qualified, and what does the "HM3" suffix indicate?
Yes, the 1.5SMC100AHM3_A/H is AEC-Q101 qualified. The "HM3" suffix denotes halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing - including high-temperature operating life, temperature cycling, and electrostatic discharge (HBM ≥8 kV). This makes the 1.5SMC100AHM3_A/H suitable for automotive powertrain and chassis applications where reliability under thermal and mechanical stress is non-negotiable.
What is the standoff voltage (VWM) and breakdown voltage (VBR) range for the 1.5SMC100AHM3_A/H?
The 1.5SMC100AHM3_A/H has a standoff voltage (VWM) of 85.5 V and a breakdown voltage (VBR) range of 95.0 V to 105 V at 1 mA test current. These values ensure the device remains non-conductive during normal operation while triggering predictably during overvoltage events - with tight VBR tolerance supporting consistent protection margins across production lots.
Can the 1.5SMC100AHM3_A/H be used in bidirectional configurations?
No, the 1.5SMC100AHM3_A/H is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC100CA). Using the 1.5SMC100AHM3_A/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
What is the thermal resistance and maximum junction temperature of the 1.5SMC100AHM3_A/H?
The 1.5SMC100AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ max) of +150 °C. These parameters are validated with the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad layout per datasheet Figure 2 - enabling reliable operation in under-hood automotive environments and sealed industrial enclosures without active cooling.
