Product details
Overview
SMCJ10AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 88.2 A peak pulse current (IPPM), and 17.0 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the SMCJ10AHE3/9AT datasheet, SMCJ10AHE3/9AT pinout, SMCJ10AHE3/9AT application, or SMCJ10AHE3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge rating, 17.0 V clamping performance at 88.2 A, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a fast-acting shunt protector that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (11.1–12.3 V). Its low incremental surge resistance and sub-nanosecond response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 150 °C maximum junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. Its unidirectional configuration uses a cathode band marking and delivers 17.0 V clamping at 88.2 A IPPM under standardized 10/1000 µs waveform conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/61T | Lower PPPM (400 W), smaller SMA package, same VWM/VBR range | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when surge energy is ≤400 W and automotive qualification is not required. |
| SMCJ10CAHE3/9AT | Bidirectional version with identical VWM/VBR but symmetrical clamping in both polarities | Used where AC-coupled or floating signal lines require protection regardless of polarity | Choose for differential bus lines (e.g., RS-485) or ungrounded sensor outputs needing bidirectional clamping. |
Compared with SMAJ10A-E3/61T and SMCJ10CAHE3/9AT, the SMCJ10AHE3/9AT provides higher surge capacity and automotive qualification - critical for 12 V/24 V vehicle subsystems where 1500 W load dump immunity and AEC-Q101 compliance are mandatory design requirements.

FAQ
What is the clamping voltage of the SMCJ10AHE3/9AT at its rated peak pulse current?
The SMCJ10AHE3/9AT has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during full-rated surge events and is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal as specified in the Vishay datasheet.
Is the SMCJ10AHE3/9AT qualified for automotive applications?
Yes, the SMCJ10AHE3/9AT is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing - making the SMCJ10AHE3/9AT suitable for under-hood and body-control module applications in passenger vehicles and commercial vehicles.
What does the "9AT" suffix indicate in SMCJ10AHE3/9AT?
"9AT" denotes the preferred packaging configuration: 13-inch diameter plastic tape and reel containing 3500 units. This format supports high-volume automated SMT placement and is distinct from the "57T" variant (7-inch reel, 850 units). The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification, while "SMCJ10A" identifies the base device type with 10 V stand-off voltage.
How does the SMCJ10AHE3/9AT differ from the bidirectional SMCJ10CAHE3/9AT?
The SMCJ10AHE3/9AT is unidirectional with cathode-band polarity, intended for DC-biased protection paths like power rails. In contrast, the SMCJ10CAHE3/9AT is bidirectional - offering symmetrical clamping in both directions with no polarity marking - and is used on AC-coupled or floating lines such as RS-485 or Ethernet PHY interfaces. Both share identical VWM, VBR, and PPPM ratings but differ in conduction behavior and layout marking requirements.
What is the thermal resistance from junction to ambient for the SMCJ10AHE3/9AT?
The typical thermal resistance from junction to ambient (RθJA) for the SMCJ10AHE3/9AT is 75 °C/W when mounted on the minimum recommended pad layout. This value assumes standard PCB copper area per the datasheet; actual thermal performance improves significantly with larger copper pours or thermal vias, which is essential for sustained surge duty cycles or elevated ambient temperatures in automotive engine compartments.
