Product details
Overview
SMCJ100CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 100 V standoff voltage (VWM), 1500 W peak pulse power (PPPM), and 162 V clamping voltage (VC) at 9.3 A IPPM. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients and lightning-induced surges.
For engineers reviewing the SMCJ100CAHM3/I datasheet, SMCJ100CAHM3/I pinout, SMCJ100CAHM3/I application, or SMCJ100CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and compatibility with automated SMT placement on 8 mm × 8 mm copper pads per terminal.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when reverse or forward voltage exceeds its breakdown threshold (VBR = 111–123 V). Its glass-passivated junction ensures stable avalanche characteristics and fast response (<1 ns).
Designed for unclamped 10/1000 μs surge waveforms, the device delivers consistent clamping performance across -55 °C to +150 °C junction temperature range, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W enabling reliable operation without active cooling in standard PCB layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC100CA | Lower PPPM (1000 W), same VWM (100 V), higher VC (170 V), non-AEC-Q101 | Limited to commercial-grade consumer/industrial use; not qualified for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin is unnecessary |
| SMCJ100CAHE3/I | Same electrical specs, RoHS-compliant but not halogen-free (E3 vs HM3), AEC-Q101 qualified | Acceptable where halogen-free requirement is waived; identical thermal and surge performance | Choose for legacy designs already using E3 suffix or where halogen content is not regulated |
Compared with SAC100CA and SMCJ100CAHE3/I, the SMCJ100CAHM3/I uniquely combines 1500 W surge rating, AEC-Q101 qualification, and halogen-free construction-making it the only option meeting full automotive Tier-1 supplier material and reliability mandates for 100 V rail protection.

FAQ
What does the 'CA' suffix indicate in SMCJ100CAHM3/I?
The 'CA' suffix in SMCJ100CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMCJ100A), SMCJ100CAHM3/I has no polarity marking and clamps equally in either direction-ideal for AC-coupled or floating signal lines where voltage polarity is undefined or reversible.
Is SMCJ100CAHM3/I suitable for automotive applications?
Yes, SMCJ100CAHM3/I is AEC-Q101 qualified and explicitly designated for automotive use via the 'HM3' suffix, which indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It meets temperature cycling, mechanical shock, and humidity resistance requirements for under-hood and chassis-mounted electronics, making SMCJ100CAHM3/I appropriate for engine control units, ADAS power supplies, and body electronics.
How does the SMCJ100CAHM3/I clamping voltage compare to its standoff voltage?
The SMCJ100CAHM3/I has a standoff voltage (VWM) of 100 V and a maximum clamping voltage (VC) of 162 V at 9.3 A IPPM-a 62 % overvoltage margin. This VC/VWM ratio of 1.62 reflects optimized avalanche dynamics for high-energy transients, ensuring protected circuits remain below absolute maximum ratings of 165 V-rated components while maintaining low leakage (<1 μA) during normal operation.
What is the thermal resistance of SMCJ100CAHM3/I and how does it affect layout?
SMCJ100CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W. To maintain TJ ≤ 150 °C under worst-case 1500 W surge, PCB layout must use minimum 8.0 mm × 8.0 mm copper pads per terminal as specified-reducing effective RθJA by ~30 %. Smaller pads increase thermal impedance and risk parametric shift or failure during repetitive surges.
Does SMCJ100CAHM3/I require special handling during reflow soldering?
No, SMCJ100CAHM3/I is rated MSL Level 1 with a maximum peak reflow temperature of 260 °C, fully compatible with standard lead-free (SnAgCu) reflow profiles. No pre-baking or moisture-sensitive handling is required. The device's glass-passivated junction and matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102, supporting high-yield automated placement and reflow in volume manufacturing.
