Product details
Overview
SMCJ16CHE3/57T 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 - deployed on power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ16CHE3/57T datasheet, SMCJ16CHE3/57T pinout, SMCJ16CHE3/57T application, or SMCJ16CHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 µA max reverse leakage at VWM, 17.8–19.7 V breakdown range, -55 °C to +150 °C operating junction temperature, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (17.8–19.7 V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage and long-term reliability under repetitive transients.
The device is rated for 1500 W peak pulse power (10/1000 µs), with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling effective heat dissipation on standard 8.0 mm × 8.0 mm copper pads. It meets MSL Level 1 and passes JESD 201 Class 2 whisker testing (HE3 suffix).
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 - guaranteed avalanche onset range at 1.0 mA test current |
| VC @ IPPM | 26.0 V - clamped voltage during 57.7 A 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 1500 W - peak transient power handling capacity under standardized surge waveform |
| ID @ VWM | 1.0 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units against load dump and jump-start transients. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between VIN and GND, clamping surges within nanoseconds. Use Value: Withstands 1500 W pulses while holding clamped voltage to 26.0 V - below absolute maximum rating of typical 3.3 V/5 V LDOs and MCUs. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop drivers) in PLC I/O modules from field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS (cathode referenced to signal return) absorbing ±2 kV contact ESD per IEC 61000-4-2. Use Value: 1.0 µA leakage at 16 V ensures no measurable error in precision current-loop calibration or sensor offset. |
| Telecom DC Power Input Protection | Motor Drive Gate Driver Protection |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges on central office equipment backplanes. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-rail, cathode-to-GND to clamp negative-going transients on negative supply rails. Use Value: 1500 W rating handles multi-kA induced surges; DO-214AB footprint allows dense layout near connectors without thermal derating penalties. |
Use Scenario: Shielding high-side gate drivers (e.g., driving N-channel MOSFETs in half-bridge inverters) from Miller-induced voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Localized TVS across gate-to-source (G-S) of power MOSFETs, triggered only during overvoltage events. Use Value: Fast <1 ns response prevents gate oxide rupture; 26.0 V clamping aligns with typical 20 V gate-rated MOSFETs' safe operating area. |
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 SMA package (DO-214AC), higher VC (27.7 V at 14.4 A) | Suitable for space-constrained consumer electronics but insufficient for automotive load dump compliance | Select SMCJ16CHE3/57T when 1500 W surge handling and AEC-Q101 qualification are mandatory |
| 1.5KE16A | Through-hole TO-218 package, same VWM/VC, but slower response and no AEC-Q101 qualification | Used in legacy industrial power supplies where board-level rework is acceptable and automotive qualification is not required | Choose SMCJ16CHE3/57T for surface-mount automation, thermal performance, and automotive-grade validation |
Compared with SMAJ16A-E3/61T and 1.5KE16A, the SMCJ16CHE3/57T delivers 3.75× higher peak power handling, AEC-Q101 validation for automotive use, and superior thermal resistance (RθJL = 15 °C/W) - making it the preferred choice for high-reliability, high-surge industrial and vehicle systems.

FAQ
What is the clamping voltage of the SMCJ16CHE3/57T under maximum surge conditions?
The SMCJ16CHE3/57T has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 57.7 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits remain within safe operating limits during transient events. The SMCJ16CHE3/57T achieves this with low incremental surge resistance, directly contributing to system-level surge immunity.
Is the SMCJ16CHE3/57T suitable for automotive applications?
Yes, the SMCJ16CHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its -55 °C to +150 °C operating junction temperature range, JESD 201 Class 2 whisker resistance, and MSL Level 1 reflow compatibility meet stringent automotive manufacturing and reliability requirements. The SMCJ16CHE3/57T is commonly deployed in engine control units, body control modules, and ADAS power domains.
How does the HE3 suffix differ from the E3 suffix in SMCJ16CHE3/57T?
The HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker testing compliance, whereas E3 indicates commercial-grade RoHS compliance only. The SMCJ16CHE3/57T is therefore validated for automotive and high-reliability industrial use, with additional stress testing for temperature cycling, highly accelerated life testing (HALT), and mechanical robustness. This distinction makes the SMCJ16CHE3/57T appropriate where long-term field reliability is non-negotiable.
What is the reverse leakage current specification for the SMCJ16CHE3/57T at its standoff voltage?
The SMCJ16CHE3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 16 V standoff voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage preserves signal integrity in precision analog circuits and minimizes standby power loss in always-on automotive modules. The SMCJ16CHE3/57T maintains this spec across its full operating temperature range, verified per JEDEC JESD22-A114.
Can the SMCJ16CHE3/57T be used in bi-directional configurations?
No - the SMCJ16CHE3/57T is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above breakdown and must be oriented with the cathode band toward the protected line. For bi-directional protection, Vishay offers the SMCJ16CA variant, which provides symmetrical clamping for AC-coupled or floating signal lines. Using the SMCJ16CHE3/57T in bi-directional roles risks forward conduction and failure.
