Product details
Overview
SMCJ16HE3/57T 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 16 V standoff voltage (VWM), 26.0 V clamping voltage (VC) at 57.7 A peak pulse current, and 1500 W peak pulse power dissipation with 10/1000 µs waveform - ideal for safeguarding MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMCJ16HE3/57T datasheet, SMCJ16HE3/57T pinout, SMCJ16HE3/57T application, or SMCJ16HE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 µA max reverse leakage at VWM, 17.8–19.7 V breakdown range, RoHS-compliant matte tin terminals, and MSL Level 1 moisture sensitivity rating.
Technical Context
The SMCJ16HE3/57T operates as a silicon avalanche diode that clamps transient overvoltages by entering breakdown when reverse voltage exceeds its VBR range (17.8–19.7 V). Its low incremental surge resistance and very fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes on DC power and signal lines.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power handling with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation across -55 °C to +150 °C junction temperature range under repetitive or single-event transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 17.8 V / 19.7 V - verified breakdown threshold at 1.0 mA test current, defining turn-on precision |
| VC @ IPPM | 26.0 V - clamped voltage during 57.7 A 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 1500 W - peak transient power absorption capability without failure |
| IPPM | 57.7 A - maximum non-repetitive surge current the device safely conducts |
| ID @ VWM | ≤1.0 µA - ultra-low leakage ensures minimal standby power loss and signal integrity |
| TJ range | -55 °C to +150 °C - enables deployment in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile case with molded epoxy body meeting UL 94 V-0 flammability rating. Cathode indicated by band on one end; leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/61T | Lower PPPM (400 W), smaller DO-214AC (SMA) package, same VWM/VC specs | Suitable only for lower-energy transients; limited thermal mass reduces surge endurance | Select when board space is critical and surge threat level is below ISO 7637-2 Pulse 5a |
| SMCJ16AHE3/57T | Identical electrical specs and AEC-Q101 qualification; differs only in marking code (GEP vs. GEP with HE3 suffix) | No functional difference; both meet same Vishay specification 88394 and packaging standards | Direct form-fit-function match; interchangeable in production with identical layout and reliability data |
Compared with SMAJ16A-E3/61T, SMCJ16HE3/57T offers 275 % higher surge power handling and superior thermal performance due to larger DO-214AB footprint; versus SMCJ16AHE3/57T, it is functionally identical with no design impact on circuit behavior or layout.

FAQ
What is the clamping voltage of the SMCJ16HE3/57T under maximum rated surge current?
The SMCJ16HE3/57T has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 57.7 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that downstream components see no more than 26.0 V during worst-case transient events, making the SMCJ16HE3/57T suitable for protecting 24 V tolerant interfaces and 16 V-rated power stages.
Is the SMCJ16HE3/57T suitable for automotive applications?
Yes, the SMCJ16HE3/57T is explicitly AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature operating life, and mechanical shock - all required for under-hood and chassis-mounted automotive electronics. Its -55 °C to +150 °C operating range, 1500 W surge rating, and DO-214AB package robustness make the SMCJ16HE3/57T appropriate for engine control units, ADAS power supplies, and infotainment system protection.
How does the HE3 suffix differ from the E3 suffix in SMCJ16HE3/57T?
The HE3 suffix in SMCJ16HE3/57T indicates AEC-Q101 qualification and compliance with JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. Both share identical electrical parameters and DO-214AB packaging, but HE3 parts undergo additional screening for automotive reliability - confirmed in Vishay document 88394. For designs requiring automotive certification, SMCJ16HE3/57T is the validated choice over SMCJ16A-E3/57T.
What is the maximum reverse leakage current for SMCJ16HE3/57T at its standoff voltage?
The SMCJ16HE3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated standoff voltage (VWM) of 16 V and ambient temperature of 25 °C. This ultra-low leakage ensures negligible power loss in always-on systems and prevents signal distortion in high-impedance sensor interfaces - a critical advantage over higher-leakage alternatives in precision analog or battery-powered applications.
Can SMCJ16HE3/57T be used in bi-directional protection circuits?
No - the SMCJ16HE3/57T is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. Bi-directional variants use the "CA" suffix (e.g., SMCJ16CA) and lack polarity marking. Using SMCJ16HE3/57T in a bi-directional configuration would result in forward conduction during negative transients, potentially causing failure. Always verify polarity and suffix: SMCJ16HE3/57T is strictly for single-polarity (positive-only transient) suppression.
