Product details
Overview
SMCJ160HE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for high-energy surge protection of DC power lines and signal paths. It features a 160 V standoff voltage (VWM), 178–197 V breakdown range (VBR), 259 V clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive power rail and industrial sensor interface protection.
For engineers reviewing the SMCJ160HE3/57T datasheet, SMCJ160HE3/57T pinout, SMCJ160HE3/57T application, or SMCJ160HE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surges, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 75 °C/W), and RoHS-compliant HE3 whisker-tested terminations.
Technical Context
The SMCJ160HE3/57T operates as a silicon avalanche diode, responding to overvoltage transients within <1 ps by entering avalanche breakdown to clamp voltage across protected circuitry. Its unidirectional polarity enables integration into DC-biased lines where reverse conduction must be blocked.
It is rated for 1500 W peak pulse power per 10/1000 µs waveform, derated linearly above 25 °C ambient per Fig. 2, and supports 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine) - critical for load-dump immunity in 24 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines upper limit of normal DC bias operation. |
| VBR min/max | 178 V / 197 V at 1 mA test current - guaranteed avalanche onset window; ensures predictable turn-on during transients. |
| VC @ IPPM | 259 V at 5.8 A - clamped voltage during full 1500 W surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - peak transient energy absorption capability with 10/1000 µs waveform; meets ISO 7637-2 Pulse 5a requirements. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient on 8 mm × 8 mm copper pads; informs heatsinking needs for repetitive surges. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for powertrain/safety-critical modules. |
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; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; blocks reverse current. |
| Cathode | Avalanche clamping node | Connected to protected line (e.g., 24 V rail); conducts surge current to anode when voltage exceeds VBR, limiting VC to 259 V. |
Key Features

Use Scenario: Protecting 24 V supply inputs of engine control modules against ISO 7637-2 load-dump transients up to 60 V superimposed on 24 V nominal. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between power rail and ground, activated only during positive overvoltage events. Use Value: Limits peak voltage to ≤259 V during 1500 W surges, preventing damage to MCU power supplies and CAN transceivers downstream. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) of pressure sensors in factory automation from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Standby-mode protector with <1 µA leakage at 160 V, ensuring minimal impact on loop accuracy during normal operation. Use Value: Clamps fast transients (<1 ns rise time) to safe levels before they corrupt ADC readings or damage op-amp input stages. |
| Telecom DC Feeder Protection | Renewable Energy Inverter Control |
|
Use Scenario: Safeguarding -48 V DC power feeds in base station remote radio units from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Reverse-biased unidirectional suppressor referenced to system ground, absorbing common-mode energy coupled onto feed lines. Use Value: Maintains 160 V standoff while delivering 259 V clamping - compatible with telecom rectifier overvoltage thresholds and battery backup margins. |
Use Scenario: Protecting gate-drive signals and auxiliary power rails in solar inverter microcontrollers from transformer-coupled switching noise and grid fault transients. IC Role / Device Role / Timing Role: Point-of-load TVS on isolated 15 V gate driver supplies, placed adjacent to optocoupler outputs. Use Value: Fast response (<1 ps) and low clamping ratio (VC/VBR ≈ 1.45) preserve timing integrity of PWM signals during 10/1000 µs surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AHE3/52T | Lower PPPM (600 W), same VWM (160 V), SMB package (smaller footprint, higher RθJA = 110 °C/W). | Suitable for space-constrained consumer electronics with lower surge exposure; not recommended for automotive load-dump. | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 3 (0.5 kV/1.0 kV). |
| SMCJ160CAHE3/57T | Bi-directional variant; identical VWM (160 V), VBR (178–197 V), and PPPM (1500 W), but no polarity marking and symmetrical clamping. | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN FD) where negative transients must also be suppressed. | Choose only if protecting floating or AC-biased nodes; unidirectional SMCJ160HE3/57T is preferred for DC rails to avoid unnecessary leakage in reverse bias. |
Compared with SMBJ160AHE3/52T, the SMCJ160HE3/57T delivers 2.5× higher surge energy handling and superior thermal dissipation; versus SMCJ160CAHE3/57T, it offers lower leakage and optimized clamping for DC-biased applications - making it the preferred choice for 24 V automotive power domains.

FAQ
What is the clamping voltage of the SMCJ160HE3/57T under a 10/1000 µs surge?
The SMCJ160HE3/57T clamps to a maximum of 259 V when subjected to its rated 5.8 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet Document Number 88394, page 2. The clamping voltage directly determines the maximum stress imposed on downstream circuitry during surge events.
Is the SMCJ160HE3/57T qualified for automotive applications?
Yes, the SMCJ160HE3/57T carries AEC-Q101 qualification (noted in the Mechanical Data section and Ordering Information table of the Vishay datasheet). This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - validating its suitability for engine control units, body electronics, and ADAS modules where reliability is mission-critical.
What does the "HE3" suffix indicate in SMCJ160HE3/57T?
The "HE3" suffix denotes two key attributes: "H" indicates AEC-Q101 qualification, and "E3" specifies RoHS-compliant construction with JESD 201 Class 2 whisker-resistant matte tin plating. This distinguishes it from commercial-grade "E3" variants and confirms compliance with automotive reliability and material safety standards.
Can the SMCJ160HE3/57T be used in bi-directional signal protection?
No - the SMCJ160HE3/57T is unidirectional and intended for DC-biased lines. For bi-directional protection (e.g., RS-485, CAN, or AC-coupled interfaces), the SMCJ160CAHE3/57T variant must be used. Using the unidirectional SMCJ160HE3/57T on floating or AC signals risks reverse conduction failure and inadequate negative transient suppression.
What is the thermal resistance of the SMCJ160HE3/57T, and how does it affect layout?
The SMCJ160HE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal (per datasheet page 3). To maintain safe junction temperatures during repetitive surges, PCB layout must provide minimum pad dimensions and consider thermal vias to inner ground planes - especially in high-temperature environments like automotive under-hood locations.
