Product details
Overview
1.5SMC100CAHM3/I from Vishay General Semiconductor is a bidirectional 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 at 137 V under 10.9 A peak pulse current, and maintains a 85.5 V stand-off voltage with ≤1.0 μA leakage at 25 °C - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC100CAHM3/I datasheet, 1.5SMC100CAHM3/I pinout, 1.5SMC100CAHM3/I application, or 1.5SMC100CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with UL 497B for telecom and automotive surge immunity standards.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding its reverse stand-off voltage (VWM = 85.5 V), it avalanches rapidly to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance.
Rated for -65 °C to +150 °C junction temperature, it supports repetitive surge duty cycles up to 0.01 % and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The bidirectional configuration eliminates polarity sensitivity, enabling symmetric protection on AC-coupled or differential lines without external orientation constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains single high-energy surges common in lightning-induced or inductive-switching events |
| Stand-off Voltage (VWM) | 85.5 V - maximum continuous reverse operating voltage before clamping initiates |
| Clamping Voltage (VC @ IPPM) | 137 V @ 10.9 A - peak voltage seen by protected circuit during rated surge condition |
| Breakdown Voltage (VBR min/max) | 95.0 V / 105 V @ 1.0 mA - defines tight 5 % tolerance window for reliable avalanche onset |
| Leakage Current (ID @ VWM) | ≤1.0 μA - negligible standby power loss and minimal interference with high-impedance signal paths |
| Junction Temperature Range | -65 °C to +150 °C - enables deployment in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and MEMS pressure sensors from load-dump and jump-start transients in engine control units. IC Role / Device Role / Timing Role: Shunt TVS diode placed directly at connector entry point to clamp fast-rising surges before reaching sensitive analog front-end ICs. Use Value: Prevents latch-up or permanent damage to 5 V or 3.3 V sensor signal conditioning circuits while maintaining <1.0 μA leakage at nominal supply. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers exposed to field wiring surges and ESD events. IC Role / Device Role / Timing Role: Bidirectional voltage clamp across input terminals to divert ±1 kV/0.5 Ω IEC 61000-4-5 surges away from precision op-amps and ADCs. Use Value: Maintains signal integrity with 137 V clamping ceiling and 85.5 V stand-off, ensuring no false triggering during normal 24 V DC operation. |
| Telecom Line Card Protection | Consumer Appliance Motor Drive |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from induced lightning surges on outdoor-facing copper ports. IC Role / Device Role / Timing Role: Primary-level TVS mounted at board edge to absorb bulk surge energy before secondary protection stages. Use Value: UL 497B certification confirms suitability for telecom infrastructure; 1500 W rating handles multi-kA induced currents per ITU-T K.20/K.21. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Bidirectional clamp across motor terminals to quench inductive kickback during PWM switching. Use Value: Fast response time and low clamping ratio (VC/VBR ≈ 1.37) minimize voltage overshoot that could damage MOSFET half-bridges or microcontroller GPIOs. |
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 peak pulse power (600 W), same SMC-compatible SMB (DO-214AA) package, 85.5 V VWM, 137 V VC | Limited to lower-energy surge environments (IEC 61000-4-5 Level 2); not AEC-Q101 qualified | Select when cost or board space is constrained and surge threat level is moderate |
| 1.5KE100CA | Higher power (1500 W), axial-leaded DO-201AE package, 85.5 V VWM, 137 V VC, no AEC-Q101 or MSL Level 1 rating | Requires through-hole assembly; unsuitable for automated SMT lines or high-reliability automotive use | Choose only for legacy through-hole designs where rework flexibility outweighs SMT efficiency |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHM3/I uniquely combines AEC-Q101 qualification, MSL Level 1 reflow compatibility, halogen-free construction, and SMC surface-mount packaging - making it the sole option for new automotive and high-volume industrial SMT designs requiring full compliance and long-term supply stability.

FAQ
What does the "CA" suffix indicate in 1.5SMC100CAHM3/I?
The "CA" suffix in 1.5SMC100CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., "A"), it has no cathode marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or differential signal paths without orientation constraints.
Is 1.5SMC100CAHM3/I qualified for automotive applications?
Yes, 1.5SMC100CAHM3/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code "HM3" suffix. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD robustness - validating its suitability for under-hood and chassis-mounted automotive systems such as engine control units, body control modules, and ADAS sensor interfaces.
What is the clamping voltage of 1.5SMC100CAHM3/I at its rated peak pulse current?
The clamping voltage (VC) of 1.5SMC100CAHM3/I is 137 V at its rated peak pulse current (IPPM) of 10.9 A, measured using the standardized 10/1000 μs double-exponential waveform. This value represents the maximum voltage imposed on protected circuitry during a full-rated surge event and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does the HM3 suffix differ from E3 or M3 in the 1.5SMC100CAHM3/I part number?
The "HM3" suffix in 1.5SMC100CAHM3/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from "E3" (RoHS-compliant commercial grade) and "M3" (halogen-free RoHS-compliant commercial grade). Only HM3 variants meet automotive reliability standards and carry the required qualification documentation for Tier 1 automotive supply chains.
Can 1.5SMC100CAHM3/I be used in place of a unidirectional TVS like 1.5SMC100AHM3/I?
No - 1.5SMC100CAHM3/I is strictly bidirectional and cannot replace unidirectional types like 1.5SMC100AHM3/I in circuits requiring forward conduction or DC bias blocking. Unidirectional devices conduct only in reverse breakdown and block forward current; substituting a bidirectional part may cause unintended conduction paths or failure to suppress forward-going transients in DC-biased lines.
