Product details
Overview
1.5SMC100CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps transients up to 137 V at 10.9 A, and features a 85.5 V stand-off voltage (VWM) with ±5% tolerance - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC100CAHM3_A/H datasheet, 1.5SMC100CAHM3_A/H pinout, 1.5SMC100CAHM3_A/H application, or 1.5SMC100CAHM3_A/H equivalent, key selection criteria include its bidirectional polarity, SMC (DO-214AB) package compatibility with automated placement, AEC-Q101 qualification, halogen-free RoHS compliance, and verified clamping performance under repetitive 0.01% duty cycle conditions.
Technical Context
This device operates as a voltage-clamped shunt protector: during overvoltage events exceeding its breakdown threshold (95–105 V at 1 mA), it rapidly transitions from high-impedance to low-impedance state, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive stress.
The 1.5SMC100CAHM3_A/H is rated for -65 °C to +150 °C operating junction temperature, exhibits 0.106 %/°C temperature coefficient of VBR, and maintains <100 nA reverse leakage at 85.5 V - enabling robust protection in thermally demanding automotive and industrial environments without thermal runaway risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 85.5 V - maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 95–105 V at 1 mA - precise avalanche initiation range ensuring consistent turn-on behavior across units and temperature |
| VC (Clamping) | 137 V at 10.9 A (10/1000 μs) - peak voltage seen by protected circuit during worst-case surge; critical for IC voltage rating margining |
| PPPM | 1500 W - energy-handling capability for transient suppression; supports IEC 61000-4-5 Level 4 (4 kV) compliance when properly laid out |
| ID (Leakage) | ≤1 μA at VWM - negligible standby power loss and no signal integrity impact on high-impedance sensor or communication lines |
| TJ max | +150 °C - enables use in under-hood automotive modules and enclosed industrial enclosures without derating concerns |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical cathode/anode terminals.

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Shunt TVS diode placed directly at connector interface to clamp transients before reaching precision ADC front-end. Use Value: Maintains signal integrity by limiting voltage excursion to ≤137 V, preventing latch-up or damage to 12-bit SAR ADCs rated for 16 V absolute max. |
Use Scenario: Safeguarding 24 V DC digital input channels on programmable logic controllers subjected to field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input filter stage, coordinated with series impedance and RC snubbing. Use Value: Enables >100,000 surge cycles at 1 kV/0.5 J without parameter drift, extending maintenance intervals in factory automation systems. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary-side surge protection on Ethernet PHY power rails (3.3 V/5 V) in PoE-powered switches vulnerable to crosstalk-induced transients. IC Role / Device Role / Timing Role: Fast-response clamping device placed adjacent to PHY IC supply pins to suppress sub-100 ns ring waves. Use Value: Sub-1 ns response time prevents voltage overshoot beyond 3.63 V on 3.3 V rail, avoiding PHY reset or data corruption. |
Use Scenario: Input-stage transient suppression on universal-input (90–264 VAC) SMPS primary side in compact wall adapters. IC Role / Device Role / Timing Role: Secondary-level clamp after MOV, absorbing residual energy not diverted by upstream protection. Use Value: Low incremental surge resistance (≈12.6 Ω) minimizes voltage overshoot during fast-rising line surges, improving overall system immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM (85.5 V), SMB package (smaller footprint, higher thermal resistance) | Best suited for space-constrained consumer electronics where surge severity is limited to IEC 61000-4-5 Level 2 | Select when board area is critical and surge energy does not exceed 0.5 J per event |
| 1.5KE100CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and higher RθJA (100 °C/W) | Used in legacy industrial controls requiring manual repairability and higher mechanical robustness | Choose only for through-hole redesigns or where rework accessibility outweighs automated manufacturing benefits |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMC package thermal performance (RθJL = 15 °C/W) - making it the preferred choice for new automotive and high-reliability industrial designs requiring both regulatory alignment and production scalability.

FAQ
What is the clamping voltage of the 1.5SMC100CAHM3_A/H under a 10/1000 μs surge?
The 1.5SMC100CAHM3_A/H clamps to a maximum of 137 V at 10.9 A under a 10/1000 μs waveform, as specified in Vishay's datasheet (Document Number: 88303, page 2). This value represents the peak voltage imposed on protected circuitry during worst-case surge conditions and is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards. The 1.5SMC100CAHM3_A/H maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is the 1.5SMC100CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC100CAHM3_A/H is AEC-Q101 qualified (indicated by the HM3 suffix) and specifically designed for automotive use. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev G. The 1.5SMC100CAHM3_A/H is commonly deployed in engine control units, ADAS camera modules, and body electronics where protection against load dump, jump-start, and ISO 7637-2 transients is required.
What does the "CA" suffix mean in 1.5SMC100CAHM3_A/H?
The "CA" suffix in 1.5SMC100CAHM3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A" suffix), the 1.5SMC100CAHM3_A/H has no polarity marking and functions identically regardless of voltage polarity, making it ideal for AC-coupled or differential signal paths such as CAN bus, RS-485, or audio lines.
What is the maximum operating temperature for the 1.5SMC100CAHM3_A/H?
The 1.5SMC100CAHM3_A/H has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. Its thermal resistance from junction to leads (RθJL) is 15 °C/W, enabling reliable operation in high-ambient environments like under-hood automotive locations or sealed industrial enclosures - provided PCB copper pad layout follows Vishay's recommended 8.0 mm × 8.0 mm minimum pad dimensions.
How does the 1.5SMC100CAHM3_A/H differ from the non-HM3 version?
The "HM3" suffix in 1.5SMC100CAHM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification, whereas base versions (e.g., "M3") lack automotive qualification and "E3" versions are commercial-grade RoHS-compliant only. The 1.5SMC100CAHM3_A/H also undergoes additional screening for high-reliability applications, including extended life testing and tighter parametric limits on leakage and clamping consistency - critical for safety-critical automotive subsystems.
