Product details
Overview
SMCJ10AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of DC power rails and signal lines. It features a 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current, and 1500 W peak pulse power rating with a 10/1000 µs waveform - deployed in automotive ECUs, industrial I/O modules, and sensor interface circuits.
For engineers reviewing the SMCJ10AHE3/57T datasheet, SMCJ10AHE3/57T pinout, SMCJ10AHE3/57T application, or SMCJ10AHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, low 0.078 %/°C VBR temperature coefficient, 1.0 µA max reverse leakage at VWM, SMC (DO-214AB) surface-mount package, and suitability for high-surge environments requiring fast response (<1 ns) and stable clamping under repetitive transients.
Technical Context
The SMCJ10AHE3/57T operates as a unidirectional avalanche diode, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response to ESD and lightning-induced surges. Its clamping behavior is defined by a low incremental surge resistance and tightly controlled VBR tolerance (±5% typical), enabling predictable protection margins in 12 V automotive and 5–24 V industrial supply rails.
Thermally, it exhibits RθJA = 75 °C/W (on standard 8 mm × 8 mm copper pads) and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C. The device is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) and meets J-STD-020 MSL Level 1, with matte tin-plated leads compliant to 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 |
|---|---|---|---|
| SMAJ10A-E3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (19.9 V at 21.6 A) | Rated for lower-energy transients; suitable for consumer-grade USB or low-power sensor nodes, not automotive load dump. | Select when space-constrained layouts require smaller footprint and surge threat level is ≤400 W (e.g., IEC 61000-4-2 only). |
| SMCJ10CAHE3/57T | Bidirectional variant; identical VWM, VBR, VC, and PPPM, but symmetric clamping in both polarities. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where polarity reversal may occur. | Choose for differential or bidirectional data lines; SMCJ10AHE3/57T remains optimal for unidirectional DC rails with defined ground reference. |

FAQ
What is the clamping voltage of the SMCJ10AHE3/57T at its rated peak pulse current?
The SMCJ10AHE3/57T has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated 10/1000 µs peak pulse current of 88.2 A. This value is measured under standardized test conditions per JEDEC and IEC standards, and defines the upper voltage limit imposed on the protected circuit during surge events. The SMCJ10AHE3/57T maintains this clamping performance across its full operating temperature range (−55 °C to +150 °C), making it suitable for under-hood automotive applications.
Is the SMCJ10AHE3/57T qualified for automotive use?
Yes, the SMCJ10AHE3/57T is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling, and unbiased highly accelerated stress testing (UHAST). The SMCJ10AHE3/57T is approved for use in automotive powertrain, chassis, and body electronics where transient immunity and long-term reliability are critical.
What is the difference between SMCJ10AHE3/57T and SMCJ10CAHE3/57T?
The SMCJ10AHE3/57T is unidirectional, with cathode marked by a band and designed for DC rail protection where polarity is fixed. The SMCJ10CAHE3/57T is bidirectional, with no polarity marking and symmetric clamping in both directions - required for AC-coupled or floating lines like RS-485 or CAN. Both share identical VWM (10 V), VBR, VC, and PPPM ratings, but the SMCJ10AHE3/57T offers lower junction capacitance and avoids unnecessary conduction in grounded systems.
What package type does the SMCJ10AHE3/57T use, and what are its mounting requirements?
The SMCJ10AHE3/57T uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.62 mm with matte tin-plated leads. For rated power dissipation, it must be mounted on minimum 8.0 mm × 8.0 mm copper pads per terminal per Vishay's datasheet Figure 2. This pad layout ensures thermal resistance RθJA = 75 °C/W and enables full 1500 W surge capability. The device is MSL Level 1 and compatible with standard lead-free reflow profiles peaking at 260 °C.
Does the SMCJ10AHE3/57T have a specified junction capacitance?
Vishay does not publish a typical junction capacitance (CJ) value for the SMCJ10AHE3/57T in the SMCJ5.0A–SMCJ188CA datasheet (Document Number 88394, Rev. 09-Jan-2024). While CJ is provided for other families (e.g., SMAJ), it is omitted for the SMCJ series in this document. For high-frequency signal line protection where capacitance matters (e.g., USB 2.0), designers should consult Vishay's application engineering team or consider alternative low-capacitance TVS devices - the SMCJ10AHE3/57T is optimized for power rail and low-speed interface protection.
