Product details
Overview
SMCJ36CA001HE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with a 10/1000 µs waveform. It features a standoff voltage of 36 V, clamping voltage of 58.1 V at 25.8 A, and operates across -55 °C to +150 °C junction temperature range. It is AEC-Q101 qualified and used for protecting automotive sensor signal lines against inductive switching surges.
For engineers reviewing the SMCJ36CA001HE3/57T datasheet, SMCJ36CA001HE3/57T pinout, SMCJ36CA001HE3/57T application, or SMCJ36CA001HE3/57T equivalent, key selection criteria include bidirectional clamping capability, 36 V stand-off rating, 1500 W surge power handling, AEC-Q101 qualification, and SMC package compatibility with automated placement on automotive PCBs.
Technical Context
The SMCJ36CA001HE3/57T implements a silicon avalanche diode structure optimized for fast transient suppression, with sub-nanosecond response time and low incremental surge resistance. Its bidirectional symmetry ensures identical clamping behavior in both polarities, enabling use on AC-coupled or floating signal paths without polarity concerns.
Designed for high-energy surge immunity per IEC 61000-4-5 (Level 4), it delivers 58.1 V clamping at 25.8 A IPPM under 10/1000 µs waveform while maintaining ≤1.0 µA reverse leakage at 36 V. Thermal resistance is 75 °C/W junction-to-ambient on standard 8 mm × 8 mm copper pads.

Use Scenario: Adding robust overvoltage protection to secondary-side DC outputs of wall adapters and USB-C PD chargers subject to user-handling ESD and output short-circuit recovery spikes. IC Role / Device Role / Timing Role: Secondary-side clamping device placed after DC-DC converter output filter to protect connected devices from output overshoot and hot-plug transients. Use Value: Clamps 36 V nominal outputs to 58.1 V during fault conditions, preventing damage to USB-PD controllers and Type-C port electronics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA-E3/61 | Same 36 V VWM and bidirectional configuration, but lower 400 W PPPM rating and SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial 1 kV surges | Select when board space is constrained and surge threat level is ≤400 W (e.g., consumer USB ports) |
| SMCJ36CAHE3_A/H | Identical electrical specs and SMC package; differs only in tape-and-reel packaging (850 pcs vs. 850 pcs) and revision code suffix | No functional difference; same AEC-Q101 qualification and thermal performance | Direct form-fit-function replacement-no design change required if sourcing flexibility or alternate reel size needed |
Compared with SMAJ36CA-E3/61, SMCJ36CA001HE3/57T provides 3.75× higher surge power handling and superior thermal dissipation in the larger SMC body; versus SMCJ36CAHE3_A/H, it shares identical protection performance but differs only in reel packaging configuration and traceability coding.

FAQ
What is the clamping voltage of SMCJ36CA001HE3/57T at its rated peak pulse current?
The SMCJ36CA001HE3/57T has a maximum clamping voltage (VC) of 58.1 V at 25.8 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for protected circuits.
Is SMCJ36CA001HE3/57T suitable for automotive applications?
Yes, SMCJ36CA001HE3/57T is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It meets requirements for temperature cycling, high-temperature reverse bias, and mechanical shock-making it appropriate for engine control units, ADAS sensors, and infotainment power rails where transient immunity is critical.
Does SMCJ36CA001HE3/57T have polarity markings on the package?
No, SMCJ36CA001HE3/57T is a bidirectional TVS and carries no cathode band or polarity marking on the SMC (DO-214AB) case. Both terminals are functionally identical, allowing flexible placement on PCBs without orientation constraints-unlike unidirectional variants which feature a visible cathode band.
What is the thermal resistance of SMCJ36CA001HE3/57T in standard mounting conditions?
The SMCJ36CA001HE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, as specified in the Vishay datasheet. This value assumes no additional heatsinking and defines safe power derating above 25 °C ambient temperature.
How does the "001" in SMCJ36CA001HE3/57T affect its specifications?
"001" in SMCJ36CA001HE3/57T is a manufacturer-specific revision or internal tracking code and does not alter electrical or mechanical specifications. All performance parameters-including 36 V VWM, 58.1 V VC, 1500 W PPPM, and AEC-Q101 qualification-match the base SMCJ36CAHE3 family as documented in Vishay's 88394 datasheet.
