Product details
Overview
SMCJ58CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 93.6 V at 16 A, and operates across -55 °C to +150 °C junction temperature range.
For engineers reviewing the SMCJ58CAHE3/9AT datasheet, SMCJ58CAHE3/9AT pinout, SMCJ58CAHE3/9AT application, or SMCJ58CAHE3/9AT equivalent, this device is selected for high-energy surge immunity in automotive power rails, industrial sensor interfaces, and telecom line protection where bidirectional clamping, AEC-Q101 qualification, and low incremental surge resistance are critical design requirements.
Technical Context
The SMCJ58CAHE3/9AT implements a glass-passivated silicon avalanche junction optimized for fast response (<1 ps) to transient overvoltages. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 1500 W peak pulse power handling under standardized 10/1000 µs waveform conditions, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation on standard PCB copper pads (8.0 mm × 8.0 mm per terminal) without heatsinking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58CA | Lower peak pulse power (500 W), smaller SMA package, higher clamping ratio | Suitable for lower-energy consumer interfaces but not automotive load dump | Select when space-constrained and surge threat level is limited to IEC 61000-4-2 only |
| 1.5KE58CA | Through-hole DO-201 package, same 58 V VWM, 1500 W rating, higher thermal mass | Better suited for prototyping or legacy through-hole designs; not AEC-Q101 qualified | Choose for manual assembly or cost-sensitive industrial controls where AEC-Q101 is not mandated |
Compared with SAC58CA and 1.5KE58CA, the SMCJ58CAHE3/9AT uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge capacity-making it the preferred choice for production automotive and high-reliability industrial PCBs requiring zero layout compromise and verified automotive lifecycle support.

FAQ
What is the clamping voltage of the SMCJ58CAHE3/9AT under maximum surge conditions?
The SMCJ58CAHE3/9AT has a maximum clamping voltage (VC) of 93.6 V at 16 A peak pulse current (IPPM), measured using the standardized 10/1000 µs waveform. This value is confirmed in the Vishay datasheet (Document Number: 88394, Revision: 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during a 1500 W transient event. The SMCJ58CAHE3/9AT maintains this clamping performance across its full operating temperature range.
Is the SMCJ58CAHE3/9AT AEC-Q101 qualified?
Yes, the SMCJ58CAHE3/9AT is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and explicitly stated in the Vishay datasheet under Mechanical Data and Ordering Information sections. This qualification confirms its suitability for automotive applications including engine control, infotainment, and ADAS subsystems where reliability under thermal cycling, vibration, and extended temperature operation is mandatory. The SMCJ58CAHE3/9AT undergoes rigorous stress testing per AEC-Q101 requirements.
What does the "CA" suffix signify in SMCJ58CAHE3/9AT?
The "CA" suffix in SMCJ58CAHE3/9AT denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities-no cathode band marking is present. This distinguishes it from unidirectional variants (e.g., SMCJ58A), which feature a cathode band and conduct only in reverse bias. The bidirectional nature of the SMCJ58CAHE3/9AT makes it ideal for AC-coupled lines, differential buses, and floating grounds where polarity cannot be assumed.
What is the standoff voltage (VWM) of the SMCJ58CAHE3/9AT?
The standoff voltage (VWM) of the SMCJ58CAHE3/9AT is 58 V, representing the maximum continuous DC or RMS voltage that can be applied across the device without triggering conduction. This parameter is specified in the Electrical Characteristics table of the Vishay datasheet and ensures compatibility with 48 V nominal systems and 56 V automotive battery rails. Operating below 58 V guarantees sub-1 µA reverse leakage, preserving system efficiency and signal fidelity.
What package type does the SMCJ58CAHE3/9AT use, and what are its key mechanical attributes?
The SMCJ58CAHE3/9AT uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.62 mm with matte tin-plated leads. It complies with MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C), supports automated placement, and features UL 94 V-0 molding compound. The package is optimized for thermal dissipation with RθJL = 15 °C/W and is rated for 150 °C maximum junction temperature-critical for under-hood automotive deployment. The SMCJ58CAHE3/9AT's footprint matches industry-standard SMC land patterns.
