Product details
Overview
SMCJ100CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge protection of DC power rails and signal lines. It features a 100 V stand-off voltage (VWM), 1500 W peak pulse power rating (10/1000 µs), clamping voltage of 162 V at 9.3 A peak pulse current, and operates across -55 °C to +150 °C junction temperature - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMCJ100CAHM3_A/I datasheet, SMCJ100CAHM3_A/I pinout, SMCJ100CAHM3_A/I application, or SMCJ100CAHM3_A/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ100CAHM3_A/I uses a glass-passivated silicon avalanche junction to achieve sub-nanosecond response to transients and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, supporting protection of AC-coupled or floating signal paths.
Rated for 1500 W peak pulse power under standardized 10/1000 µs waveform, it delivers stable clamping performance up to 150 °C junction temperature and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak). The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery rail in body control module exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping device absorbing >100 V transients before they reach LDOs and microcontrollers. Use Value: Withstands 1500 W surges and maintains clamping below 162 V, preserving downstream 3.3 V/5 V logic integrity. |
Use Scenario: CAN FD or LIN bus lines interfacing with temperature/pressure sensors in factory automation. IC Role / Device Role / Timing Role: Bidirectional transient shunt protecting differential signaling against ESD and inductive switching noise. Use Value: Symmetrical clamping eliminates need for dual unidirectional devices, reducing BOM count and PCB area. |
| Telecom DC Power Feeds | Consumer Device USB Power Ports |
Use Scenario: -48 V telecom power distribution board subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary-level surge suppression stage following gas discharge tube primary protection. Use Value: 100 V VWM aligns with -48 V nominal system, allowing safe operation while clamping fast-rising transients. |
Use Scenario: 5 V USB Type-C power delivery path in smart home hubs vulnerable to hot-plug transients. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) TVS placed directly at connector to limit ESD energy entering PMIC. Use Value: Halogen-free HM3 construction supports consumer safety certifications; AEC-Q101 grade adds robustness beyond typical commercial use. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC100CA | Same 100 V VWM and bidirectional function, but lower 600 W PPPM rating and TO-220AC package | Requires through-hole mounting and heatsinking; unsuitable for high-density SMT designs | Select when higher thermal mass is needed and board space allows larger footprint |
| SMCJ100AHE3_A/I | Identical electrical specs and SMC package, but RoHS-compliant without halogen-free certification (E3 vs HM3) | Lacks JESD201 Class 2 whisker resistance and halogen-free assurance required for some automotive OEMs | Choose SMCJ100CAHM3_A/I when AEC-Q101 + halogen-free compliance is mandatory |
Compared with SAC100CA and SMCJ100AHE3_A/I, the SMCJ100CAHM3_A/I uniquely combines 1500 W surge capability, SMC surface-mount form factor, AEC-Q101 qualification, and halogen-free construction - making it the only option meeting full Tier-1 automotive power rail protection requirements without layout or thermal compromise.

FAQ
What does the 'CA' suffix indicate in SMCJ100CAHM3_A/I?
The 'CA' suffix in SMCJ100CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., SMCJ100A), the SMCJ100CAHM3_A/I has no cathode marking and clamps equally for positive and negative transients - essential for protecting AC-coupled or floating signal lines without polarity constraints.
Is SMCJ100CAHM3_A/I qualified for automotive applications?
Yes, SMCJ100CAHM3_A/I is AEC-Q101 qualified, verified per stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). This qualification confirms suitability for automotive power domains such as body control modules, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
How does the HM3 suffix differ from E3 or M3 in SMCJ100CAHM3_A/I?
The HM3 suffix in SMCJ100CAHM3_A/I specifies halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance - exceeding baseline E3 (RoHS only) and M3 (halogen-free RoHS, non-AEC-Q101) variants. This makes SMCJ100CAHM3_A/I appropriate for automotive OEMs mandating both halogen-free materials and AEC-Q101 validation, whereas E3/M3 lack the full automotive qualification.
What is the maximum clamping voltage of SMCJ100CAHM3_A/I during a surge event?
The maximum clamping voltage (VC) of SMCJ100CAHM3_A/I is 162 V at 9.3 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated 1500 W transient, ensuring downstream components like 12 V regulators or 5 V logic remain within safe operating margins.
Can SMCJ100CAHM3_A/I be used in place of unidirectional SMCJ100A variants?
No - SMCJ100CAHM3_A/I is strictly bidirectional and lacks polarity marking, while SMCJ100A is unidirectional with a defined cathode band. Substituting SMCJ100CAHM3_A/I for SMCJ100A in DC-biased circuits may cause unintended forward conduction or failure to clamp correctly. Use SMCJ100CAHM3_A/I only where symmetrical protection is required, such as AC lines or floating buses.
