Product details
Overview
SMCJ10HE3/57T from Vishay is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the SMCJ10HE3/57T datasheet, SMCJ10HE3/57T pinout, SMCJ10HE3/57T application, or SMCJ10HE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity marking, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10HE3/57T operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its 11.1–12.3 V minimum/maximum breakdown voltage (VBR) at 10 mA test current. Its low incremental surge resistance enables fast response (<1 ns) to transients induced by inductive load switching or ESD events.
It is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. The device uses glass-passivated chip junction construction, meets MSL Level 1 per J-STD-020, and has matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 11.1 V / 12.3 V at IT = 10 mA - Ensures reliable turn-on within defined tolerance band |
| VC @ IPPM | 17.0 V at 88.2 A - Clamping voltage limits downstream circuit stress during 10/1000 µs surge |
| PPPM | 1500 W - Peak transient energy absorption capability under standardized waveform |
| ID @ VWM | 5.0 µA - Low leakage preserves signal integrity and system quiescent current |
| RθJA | 75 °C/W - Thermal resistance determines required PCB copper area for safe power dissipation |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to shunt surges exceeding 13.2 V. Use Value: Clamps to ≤17.0 V within nanoseconds, preventing damage to downstream DC-DC converters and microcontrollers rated for 16 V absolute max. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) from ESD and field-wiring faults. IC Role / Device Role / Timing Role: TVS connected across signal and return path to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-µA leakage at 10 V ensures minimal impact on loop accuracy; 1500 W PPPM handles multiple surge events without degradation. |
| Consumer Device USB Port Surge Suppression | Telecom Base Station DC Input Stage |
Use Scenario: Adding secondary overvoltage protection on USB VBUS lines after primary front-end filtering. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to GND, triggered only during positive overvoltage events on +5 V rail. Use Value: 17.0 V clamping prevents latch-up in USB controller ICs while maintaining <5 µA standby leakage for battery-powered devices. | Use Scenario: Protecting -48 V telecom rectifier outputs from lightning-induced surges on outdoor feeder lines. IC Role / Device Role / Timing Role: Reverse-connected SMCJ10HE3/57T (cathode to -48 V, anode to ground) clamps negative-going transients. Use Value: Withstands 200 A IFSM (8.3 ms half-sine), enabling resilience against multi-kA induced surges without fuse coordination issues. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/52T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (~150 °C/W) | Suitable for space-constrained consumer boards with lower surge exposure | Select when board area is limited and peak surge energy does not exceed 400 W |
| 1.5KE10A | Through-hole TO-218 package, same VWM/VC specs, higher IFSM (250 A), no AEC-Q101 qualification | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is preferred | Choose for cost-sensitive, non-automotive designs requiring proven field reliability but no automotive qualification |
Compared with SMAJ10A-E3/52T and 1.5KE10A, the SMCJ10HE3/57T delivers superior surge robustness (1500 W vs. 400 W or ~1500 W with larger thermal mass), AEC-Q101 compliance for automotive use, and optimized SMT manufacturability - making it the preferred choice for new automotive and high-reliability industrial designs requiring automated assembly and validated qualification.

FAQ
What is the breakdown voltage range of the SMCJ10HE3/57T?
The SMCJ10HE3/57T has a guaranteed breakdown voltage (VBR) range of 11.1 V to 12.3 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable turn-on behavior during overvoltage events and supports accurate system-level surge margin analysis for the SMCJ10HE3/57T in design validation.
Is the SMCJ10HE3/57T suitable for automotive applications?
Yes, the SMCJ10HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, MSL Level 1 reflow compatibility, and tested performance across -55 °C to +150 °C junction temperature range - all confirmed in Vishay's qualification report for the SMCJ10HE3/57T.
How does the clamping voltage of the SMCJ10HE3/57T compare to its stand-off voltage?
The SMCJ10HE3/57T has a 10 V stand-off voltage (VWM) and clamps to a maximum of 17.0 V at 88.2 A (10/1000 µs). This 7.0 V differential defines the protective margin for downstream components - ensuring that even under worst-case surge conditions, the SMCJ10HE3/57T limits voltage stress to levels compatible with 16 V-rated ICs and MOSFETs.
What is the meaning of the "HE3/57T" suffix in SMCJ10HE3/57T?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with JESD 201 Class 2 whisker resistance; "57T" denotes packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This full designation confirms the exact manufacturing and packaging configuration of the SMCJ10HE3/57T as shipped by Vishay.
Can the SMCJ10HE3/57T be used in bidirectional configurations?
No - the SMCJ10HE3/57T is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and cathode band marking. For bidirectional protection, Vishay specifies parts like SMCJ10CA; using the SMCJ10HE3/57T in reverse-biased mode would result in forward conduction and potential failure. Always verify polarity per the SMCJ10HE3/57T datasheet.
