Product details
Overview
SMCJ10A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the SMCJ10A-E3/57T datasheet, SMCJ10A-E3/57T pinout, SMCJ10A-E3/57T application, or SMCJ10A-E3/57T equivalent, key selection criteria include clamping performance under 88.2 A surge, thermal resistance (RθJA = 75 °C/W), unidirectional polarity marking (cathode band), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10A-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to transients induced by inductive switching or ESD. Its low incremental surge resistance ensures minimal voltage overshoot during 10/1000 µs surges up to 1500 W, while its MSL Level 1 rating supports lead-free reflow up to 260 °C peak.
Designed for unidirectional DC line protection, it exhibits 5.0 µA maximum reverse leakage at 10 V VWM and a positive temperature coefficient of VBR (+0.078 %/°C), enabling stable clamping across -55 °C to +150 °C operating junction range without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse working voltage before clamping activation |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - Confirmed avalanche onset range ensuring reliable turn-on margin above VWM |
| VC @ IPPM | 17.0 V at 88.2 A - Clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform, validated on 8 mm × 8 mm copper pads |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance defining derating above 25 °C ambient |
| IFSM | 200 A - Non-repetitive forward surge rating for 8.3 ms half-sine, supporting inrush tolerance |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |

|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in body control modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, clamping transients before they reach LDO input. Use Value: 17.0 V clamping ensures MCU VDD remains below absolute maximum rating during 100 V/500 ms load dump events. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC analog input cards from field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting transients to chassis ground before signal conditioning circuitry. Use Value: Sub-ns response and 1500 W PPPM handle ±8 kV contact ESD per IEC 61000-4-2 without degradation. |
| Telecom DC Power Input Protection | Consumer Device USB Port Protection |
Use Scenario: Securing 48 V DC input of PoE-powered network switches against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary TVS on main DC bus, coordinated with upstream MOVs and downstream filtering. Use Value: 1500 W rating sustains multiple 10/1000 µs surges up to 100 A without parametric shift or failure. | Use Scenario: Adding secondary overvoltage protection on VBUS line of USB-C ports in portable monitors to guard against adapter fault conditions. IC Role / Device Role / Timing Role: Secondary clamp after primary fuse and common-mode choke, absorbing residual transients missed by front-end filters. Use Value: 10 V VWM aligns with USB 2.0/3.0 VBUS tolerance, while 17.0 V VC prevents damage to USB controller ICs rated to 20 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10A-TB-E3/57T | Same VWM (10 V), lower PPPM (600 W), smaller SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for load dump or high-current lightning surges | Select only for space-constrained consumer designs with <600 W surge requirements |
| 1.5KE10A | Through-hole TO-218 package, identical VWM/VBR/VC specs, higher RθJA (100 °C/W) | Requires PCB real estate and wave soldering; less suitable for high-density SMT layouts | Choose when legacy through-hole manufacturing or higher thermal mass is preferred |
Compared with SAC10A-TB-E3/57T and 1.5KE10A, the SMCJ10A-E3/57T delivers optimal balance of 1500 W surge capacity, SMT compatibility, and thermal performance in compact SMC packaging - making it preferred for new automotive and industrial designs requiring robust, automated assembly.

FAQ
What is the clamping voltage of SMCJ10A-E3/57T at its rated peak pulse current?
The SMCJ10A-E3/57T has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 88.2 A, measured using a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The SMCJ10A-E3/57T maintains this clamping performance when mounted on the specified 8.0 mm × 8.0 mm copper pad layout.
Is SMCJ10A-E3/57T suitable for automotive applications?
Yes, the SMCJ10A-E3/57T is RoHS-compliant and compatible with AEC-Q101-qualified variants (e.g., SMCJ10AHE3); while the E3/57T suffix itself denotes commercial-grade qualification, its electrical specs - including 1500 W PPPM, -55 °C to +150 °C TJ range, and MSL Level 1 - meet core requirements for under-hood and body electronics. For certified automotive use, specify the HE3 suffix version of SMCJ10A-E3/57T.
How does the SMCJ10A-E3/57T differ from bidirectional SMCJ10CA variants?
The SMCJ10A-E3/57T is unidirectional, featuring a cathode band and conducting only in reverse bias above VBR, whereas SMCJ10CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. The SMCJ10A-E3/57T offers lower leakage (<5.0 µA at 10 V) and supports forward surge current (IFSM = 200 A), making it ideal for DC rail protection; SMCJ10CA suits AC-coupled or floating signal lines.
What is the thermal resistance of SMCJ10A-E3/57T, and how does it affect power derating?
The SMCJ10A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted per recommended pad layout. This means power dissipation must be derated linearly above 25 °C ambient - for example, at 75 °C ambient, its 6.5 W steady-state power rating drops to ~3.25 W. The SMCJ10A-E3/57T relies on PCB copper area for heat spreading, not heatsinks, so layout adherence is critical for thermal integrity.
Can SMCJ10A-E3/57T be used in parallel for higher surge current handling?
No - SMCJ10A-E3/57T should not be paralleled without external balancing resistors due to VBR tolerance (±5.5 %) causing current imbalance and potential thermal runaway. Vishay specifies single-device operation only; for >88.2 A surge capability, select a higher-rated device like SMCJ15A or SMCJ24A instead of paralleling SMCJ10A-E3/57T units.
