Product details
Overview
SMCJ100CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 100 V stand-off voltage (VWM), 162 V maximum clamping voltage (VC) at 9.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed on power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ100CA-E3/57T datasheet, SMCJ100CA-E3/57T pinout, SMCJ100CA-E3/57T application, or SMCJ100CA-E3/57T equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, AEC-Q101 qualification status, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ100CA-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both directions due to its bidirectional construction. Its breakdown voltage (VBR) ranges from 111 V to 123 V at 1 mA test current, with temperature coefficient of +0.107 %/°C - enabling stable performance across -55 °C to +150 °C operating junction range.
It meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 200 A non-repetitive forward surge current (IFSM) only in unidirectional variants (not applicable here), and exhibits <1 μA reverse leakage at VWM - critical for low-power sensor interface protection where standby current integrity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 111 V / 123 V at 1 mA - defines reliable avalanche onset window under standardized test conditions |
| VC @ IPPM | 162 V at 9.3 A - clamping voltage during 10/1000 μs surge, limiting downstream voltage stress |
| PPPM | 1500 W - peak transient energy absorption capability without failure |
| TJ max | +150 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Package | SMC (DO-214AB) - surface-mount outline with 7.75 mm × 8.13 mm footprint and 2.06 mm height |
| RoHS | E3 suffix - lead-free, RoHS-compliant matte tin-plated terminals, qualified per JESD 201 Class 2 |
Pinout & Package
SMCJ100CA-E3/57T uses the SMC (DO-214AB) package: a two-terminal, bidirectional device with no polarity marking - both terminals are electrically symmetric and interchangeable. The case is molded compound rated UL 94 V-0, with leads extending 1.52 mm minimum from body edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identical roles; bidirectional clamping occurs regardless of voltage polarity applied |
| Case (body) | Thermal mass / mechanical anchor | Non-electrical; provides thermal dissipation path to PCB copper pads (8.0 mm × 8.0 mm recommended) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) in properly laid out PCBs |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes voltage overshoot during transients - critical for 100 V-rated MOSFET gate drivers and CAN FD bus protection |
| AEC-Q101 qualification option | HE3/HM3 variants available; E3 suffix indicates commercial-grade but shares same die and construction |
| MSL Level 1 rating | Allows single-reflow assembly without moisture sensitivity handling - reduces manufacturing complexity |
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-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VC specs | Suitable for space-constrained consumer ports but insufficient for industrial load dump | Select when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
| SMCJ100A-E3/57T | Unidirectional variant; cathode band marked; identical VWM/VC/PPPM but asymmetric conduction | Required for DC-biased rails where reverse conduction must be blocked | Choose only if circuit topology mandates unidirectional blocking - otherwise SMCJ100CA-E3/57T offers broader flexibility |
Compared with SMBJ100CA-E3/52T and SMCJ100A-E3/57T, the SMCJ100CA-E3/57T uniquely balances 1500 W surge capacity, bidirectional symmetry, and SMC package thermal robustness - making it optimal for automotive and industrial applications demanding full-spectrum transient immunity without polarity constraints.

FAQ
What is the clamping voltage of SMCJ100CA-E3/57T at its rated peak pulse current?
The SMCJ100CA-E3/57T has a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current (IPPM), measured using the standard 10/1000 μs double-exponential surge waveform. This value ensures predictable voltage limiting during real-world transients and is verified per ANSI/IEEE C62.35 test methods. The SMCJ100CA-E3/57T maintains this clamping performance across its full operating temperature range.
Is SMCJ100CA-E3/57T suitable for automotive applications?
The SMCJ100CA-E3/57T itself carries the commercial-grade E3 suffix and is not AEC-Q101 qualified; however, it shares identical die, packaging, and electrical characteristics with the AEC-Q101-qualified SMCJ100CAHE3 variant. For non-safety-critical automotive subsystems like body control modules or infotainment power rails, the SMCJ100CA-E3/57T is widely used - but safety-critical applications require explicit HE3/HM3 ordering codes. The SMCJ100CA-E3/57T operates reliably from -55 °C to +150 °C.
How does the bidirectional design of SMCJ100CA-E3/57T affect PCB layout?
The bidirectional design of SMCJ100CA-E3/57T eliminates polarity marking requirements - both terminals are functionally identical, allowing unrestricted orientation during automated placement. No silkscreen polarity indicator is needed, simplifying layout and reducing assembly errors. Thermal performance relies on symmetric 8.0 mm × 8.0 mm copper pads per terminal, and the SMCJ100CA-E3/57T's DO-214AB footprint is compatible with standard SMC land patterns defined in IPC-7351.
What is the maximum reverse leakage current for SMCJ100CA-E3/57T at its stand-off voltage?
At its 100 V stand-off voltage (VWM), the SMCJ100CA-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, per the Vishay datasheet. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-operated systems. Leakage remains below 5 μA up to +125 °C ambient, ensuring stability across extended temperature operation. The SMCJ100CA-E3/57T achieves this with glass-passivated junction technology.
Can SMCJ100CA-E3/57T be used in parallel for higher surge current handling?
No - SMCJ100CA-E3/57T is not designed for parallel operation due to parametric mismatch in breakdown voltage (VBR tolerance ±5 %) causing current imbalance and potential thermal runaway. For higher surge ratings, select a single higher-power device such as SMCJ150CA-E3/57T (243 A IPPM) or use staged protection (e.g., GDT + SMCJ100CA-E3/57T). The SMCJ100CA-E3/57T's 1500 W rating is intended for standalone use with proper PCB thermal relief.
