Product details
Overview
SMCJ100HE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of power rails and signal lines. It features a 100 V standoff voltage (VWM), 111–123 V breakdown range (VBR at 1 mA), 162 V clamping voltage (VC) at 9.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial motor drive DC bus protection.
For engineers reviewing the SMCJ100HE3/57T datasheet, SMCJ100HE3/57T pinout, SMCJ100HE3/57T application, or SMCJ100HE3/57T equivalent, this device is selected for high-energy surge immunity in AEC-Q101 qualified systems where low clamping ratio, fast response (<1 ns), and stable thermal performance up to 150 °C junction temperature are critical.
Technical Context
The SMCJ100HE3/57T operates as a silicon avalanche diode with glass-passivated junction, enabling precise reverse-biased breakdown behavior under transient stress. Its unidirectional polarity uses a cathode band marking and exhibits 1.0 µA maximum reverse leakage at 100 V, with thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads.
It delivers 1500 W peak pulse power per 10/1000 µs waveform, derated linearly above 25 °C ambient, and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). The device meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHE3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs. | Suitable for space-constrained consumer PCBs but not for automotive load dump where 1500 W is required. | Select only when surge energy is ≤600 W and board area is limited; verify thermal dissipation on reduced pad size. |
| SMCJ100A-E3/57T | Same electrical specs and DO-214AB package, but commercial-grade (non-AEC-Q101), no HE3 whisker rating. | Acceptable for industrial controls without automotive qualification mandates; lower cost but not for safety-critical modules. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated; confirm lifecycle support separately. |
Compared with SMCJ100HE3/57T, the SMBJ100AHE3/52T trades surge capacity for footprint reduction, while the SMCJ100A-E3/57T omits automotive qualification - making the HE3/57T uniquely suited for AEC-Q101-compliant, high-energy protection where both reliability and power handling are mandatory.

FAQ
What is the clamping voltage of the SMCJ100HE3/57T under maximum rated surge current?
The SMCJ100HE3/57T has a maximum clamping voltage (VC) of 162 V at its rated peak pulse current of 9.3 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits experience no more than 162 V during worst-case transient events. The SMCJ100HE3/57T maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is the SMCJ100HE3/57T suitable for automotive applications?
Yes, the SMCJ100HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its construction includes JESD 201 Class 2 whisker resistance, MSL Level 1 moisture sensitivity, and validation across temperature cycling, HAST, and mechanical shock tests. The SMCJ100HE3/57T is commonly deployed in engine control modules, body control units, and ADAS power supplies where reliability under transient stress is mission-critical.
What does the "HE3" suffix indicate in SMCJ100HE3/57T?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance and halogen-free molding compound. It distinguishes the SMCJ100HE3/57T from commercial-grade variants (e.g., "E3") and confirms compliance with automotive reliability and environmental standards. The SMCJ100HE3/57T's HE3 marking is verified in Vishay document 88394 and supported by traceable manufacturing lot data.
How does the SMCJ100HE3/57T differ from bi-directional SMCJ100CA variants?
The SMCJ100HE3/57T is unidirectional, with a cathode band and forward conduction capability, whereas SMCJ100CA is bi-directional and lacks polarity marking. The SMCJ100HE3/57T offers 200 A forward surge rating (IFSM), while bi-directional types do not specify IFSM. Clamping behavior differs: the SMCJ100HE3/57T clamps only in reverse, making it ideal for DC rail protection; SMCJ100CA clamps in both directions, suited for AC or differential signal lines.
What is the thermal resistance and recommended mounting for optimal performance of the SMCJ100HE3/57T?
The SMCJ100HE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. To maintain reliability under repeated surges, use minimum recommended pad layout per Vishay's DO-214AB outline drawing, ensure solder coverage ≥95%, and avoid thermal vias that reduce effective copper area. The SMCJ100HE3/57T's RθJL is 15 °C/W, confirming efficient heat transfer to PCB copper.
