Product details
Overview
1.5SMC100CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V standoff voltage (VWM), 114–126 V breakdown voltage (VBR), 137 V maximum clamping voltage at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC100CAHE3_A/I datasheet, 1.5SMC100CAHE3_A/I pinout, 1.5SMC100CAHE3_A/I application, or 1.5SMC100CAHE3_A/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, SMC (DO-214AB) package thermal resistance (RθJL = 15 °C/W), and low leakage (<1 μA at VWM) under harsh ambient conditions.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), while the low incremental surge resistance supports effective energy diversion without thermal runaway.
The device is rated for continuous operation from –65 °C to +150 °C junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 1500 W peak pulse power rating is specified with strict derating above 25 °C ambient, and it sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) in unidirectional mode - though 1.5SMC100CAHE3_A/I is bidirectional and thus not rated for IFSM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 114–126 V at 1 mA test current - precise conduction onset ensures predictable transient suppression timing |
| VC (Clamping Voltage) | 137 V at 10.9 A IPPM - limits downstream voltage stress during 10/1000 μs surges to protect 100 V-rated ICs |
| PPPM (Peak Pulse Power) | 1500 W - enables handling of high-energy lightning-induced transients per IEC 61000-4-5 Level 4 |
| ID (Reverse Leakage) | <1 μA at 100 V - minimizes standby power loss and avoids false triggering in high-impedance circuits |
| TJ max | +150 °C - supports under-hood automotive use and industrial environments with elevated ambient temperatures |
| Package | SMC (DO-214AB) - standardized surface-mount footprint with 8.0 mm × 8.0 mm copper pad thermal relief for 6.5 W steady-state dissipation |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with cathode in bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; no polarity marking on bidirectional devices like 1.5SMC100CAHE3_A/I |
Key Features

| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in industrial enclosures |
| Low clamping ratio (VC/VBR ≈ 1.12) | Minimizes let-through voltage - critical for protecting 100 V bus rails and wide-VDS MOSFET gate drivers |
| MSL Level 1, 260 °C peak | Compatible with standard lead-free reflow profiles without preconditioning or dry-pack requirements |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller thermal mass) | Limited to lower-energy transients (e.g., IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3+ | Select when board space is constrained and surge threat level is limited to ESD and capacitive coupling. |
| 1.5KE100CA | Higher leakage (5 μA), axial-leaded DO-201 package, slower response due to lead inductance | Not suitable for automated SMT assembly or high-frequency transient suppression; requires through-hole layout | Choose only for legacy through-hole designs where rework to SMC is impractical and 1500 W rating remains essential. |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHE3_A/I delivers superior surge handling in an AEC-Q101-qualified SMT package, enabling compact, automotive-compliant designs with guaranteed 1500 W clamping performance and sub-μA leakage - critical for precision analog and safety-critical subsystems.

FAQ
What is the clamping voltage of the 1.5SMC100CAHE3_A/I at its rated peak pulse current?
The 1.5SMC100CAHE3_A/I has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM), measured using the standard 10/1000 μs double-exponential waveform. This value ensures protected circuits remain below critical voltage thresholds during high-energy transients, and is verified per Vishay's test methodology in Document Number 88303.
Is the 1.5SMC100CAHE3_A/I suitable for automotive applications?
Yes, the 1.5SMC100CAHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in Vishay's 1.5SMC Series specification (Rev. 09-Mar-2026). It undergoes rigorous stress testing for temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for engine control units, ADAS sensor modules, and body electronics where reliability is mandated.
Does the 1.5SMC100CAHE3_A/I have polarity markings on the package?
No, the 1.5SMC100CAHE3_A/I is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) case. Unlike unidirectional variants (e.g., 1.5SMC100A), it functions identically in both directions - eliminating orientation concerns during automated placement and simplifying PCB layout for symmetric protection schemes.
What is the thermal resistance from junction to leads (RθJL) for the 1.5SMC100CAHE3_A/I?
The 1.5SMC100CAHE3_A/I has a typical thermal resistance from junction to leads (RθJL) of 15 °C/W, as specified in the Thermal Characteristics table of Vishay's 1.5SMC Series datasheet. This low value enables efficient heat transfer to PCB copper pads, supporting its 6.5 W steady-state power dissipation rating when mounted on 8.0 mm × 8.0 mm copper areas.
How does the 1.5SMC100CAHE3_A/I differ from the unidirectional 1.5SMC100AHE3_A/I?
The 1.5SMC100CAHE3_A/I is bidirectional with symmetrical clamping in both polarities and no cathode band marking, whereas the 1.5SMC100AHE3_A/I is unidirectional, features a cathode band, and supports 200 A IFSM (8.3 ms surge). The "CA" suffix denotes bidirectional functionality - critical for AC-coupled or floating signal line protection where polarity reversal may occur.
