Product details
Overview
SMCJ100HE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 100 V standoff voltage (VWM), 111–123 V breakdown range (VBR), 162 V clamping voltage (VC) at 9.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive power rails and industrial I/O interfaces against ESD and load dump transients.
For engineers reviewing the SMCJ100HE3/9AT datasheet, SMCJ100HE3/9AT pinout, SMCJ100HE3/9AT application, or SMCJ100HE3/9AT equivalent, this page delivers verified electrical parameters, mechanical package details, real-world use cases, and validated alternative parts - all aligned with Vishay's official SMCJ series specification document 88394 (Rev. 11-Dec-12).
Technical Context
The SMCJ100HE3/9AT operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (VBR = 111–123 V), thereby clamping transient energy to ≤162 V at 9.3 A. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
Thermally, it sustains 150 °C maximum junction temperature with RθJA = 75 °C/W and RθJL = 15 °C/W, and is rated for 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, making it suitable for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working limit. |
| VBR min/max | 111 V / 123 V - Breakdown occurs within this range at 1 mA test current; ensures consistent turn-on across production lots. |
| VC @ IPPM | 162 V at 9.3 A - Clamped voltage during 10/1000 µs transient; determines maximum stress imposed on protected circuitry. |
| PPPM | 1500 W - Peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 5a. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at rated standoff; low value minimizes standby power loss and avoids false triggering. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in engine control units and power converters. |
| Qualification | AEC-Q101 qualified - Validated for automotive reliability including temperature cycling, humidity, and mechanical shock. |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band on one end; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or lower-potential rail; completes clamping path during overvoltage events. |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V supply); initiates avalanche conduction when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, mechanical shock, and humidity exposure. |
| Glass-passivated junction | Ensures stable VBR tolerance, low leakage drift over time, and immunity to moisture-induced degradation. |
| Low incremental surge resistance | Minimizes VC rise under high-current transients, improving protection margin for downstream ICs. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or dry-pack requirements. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under thermal stress, eliminating risk of latent short circuits in long-life systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100AHE3/A | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR/VC specs. | Suitable for space-constrained consumer electronics but insufficient for automotive load dump. | Select when board area is limited and surge energy is ≤400 W; not recommended for AEC-Q101 systems. |
| SMCJ100A-E3/9AT | Same electrical specs and DO-214AB package, but commercial-grade (non-AEC-Q101), Class 1A whisker rating. | Acceptable for industrial controls where automotive qualification is not mandated. | Choose for cost-sensitive non-automotive designs requiring identical clamping performance and footprint. |
Compared with SMCJ100HE3/9AT, SMAJ100AHE3/A offers reduced surge capacity in a smaller package, while SMCJ100A-E3/9AT matches form/fit/function but lacks AEC-Q101 validation - making the HE3 variant the sole choice for automotive under-hood deployment.

FAQ
What is the clamping voltage of the SMCJ100HE3/9AT and how is it measured?
The SMCJ100HE3/9AT has a maximum clamping voltage (VC) of 162 V, measured at 9.3 A peak pulse current using a standardized 10/1000 µs double-exponential waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events, and is guaranteed per Vishay specification document 88394.
Is the SMCJ100HE3/9AT suitable for automotive applications?
Yes, the SMCJ100HE3/9AT is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C, with JESD 201 Class 2 whisker resistance and MSL Level 1 reflow compatibility. These attributes make it appropriate for engine control modules, body electronics, and ADAS power domains where reliability under thermal and mechanical stress is mandatory.
How does the HE3 suffix differ from E3 in Vishay SMCJ part numbering?
The HE3 suffix on SMCJ100HE3/9AT denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only (JESD 201 Class 1A). Both share identical electrical characteristics and DO-214AB packaging, but HE3 is required for automotive under-hood use.
What is the reverse leakage current of the SMCJ100HE3/9AT at its standoff voltage?
The SMCJ100HE3/9AT exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 100 V standoff voltage (VWM), tested at 25 °C. This low leakage preserves power efficiency in always-on systems and prevents false triggering in high-impedance sensing circuits.
Can the SMCJ100HE3/9AT be used in bidirectional configurations?
No - the SMCJ100HE3/9AT is a unidirectional device, indicated by the "A" suffix (not "CA"). Bidirectional operation requires the CA variant (e.g., SMCJ100CA), which lacks polarity marking and conducts symmetrically in both directions. Using SMCJ100HE3/9AT in reverse-biased AC applications risks permanent failure.
