Product details
Overview
SMCJ36CHE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for high-energy surge protection on power and signal lines. It features a 36 V stand-off voltage (VWM), 58.1 V maximum clamping voltage (VC) at 25.8 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMCJ36CHE3/57T datasheet, SMCJ36CHE3/57T pinout, SMCJ36CHE3/57T application, or SMCJ36CHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surges, bi-directional symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
The SMCJ36CHE3/57T operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with minimum breakdown voltage (VBR) of 40.0 V and maximum of 44.2 V at 1 mA test current. Its low incremental surge resistance enables stable clamping during fast transients, while glass passivated junction ensures reliability under repetitive surge stress.
Designed for surface-mount placement on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power handling with derating above TA = 25 °C per Fig. 2. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36AHE3/A | Lower PPPM (400 W), SMA package (DO-214AC), unidirectional only, same VWM but higher VC (68.7 V @ 5.8 A). | Not suitable for bi-directional AC signals; limited to DC rail protection with cathode orientation. | Select when space-constrained layouts require smaller footprint and surge energy is ≤400 W. |
| SMCJ36CAHE3/57T | Identical specifications and packaging; CA suffix explicitly denotes bi-directional version (same as SMCJ36CHE3/57T per Vishay documentation). | No functional difference; CA and HE3/57T denote same device family and qualification level. | Preferred for procurement clarity when specifying bi-directional function in BOMs or design reviews. |
Compared with SMAJ36AHE3/A and SMCJ36CAHE3/57T, the SMCJ36CHE3/57T offers superior 1500 W surge capacity in a robust DO-214AB package with AEC-Q101 validation-making it optimal for automotive and industrial systems requiring high-energy clamping without polarity constraints.

FAQ
What does the "HE3/57T" suffix mean in SMCJ36CHE3/57T?
The HE3 suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker-resistant matte tin plating. The /57T denotes packaging in 7-inch plastic tape-and-reel format with 850 units per reel, optimized for automated SMT placement.
Is SMCJ36CHE3/57T bi-directional or uni-directional?
SMCJ36CHE3/57T is bi-directional, confirmed by its CA-type designation in Vishay's SMCJ5.0A–SMCJ188CA family documentation. It exhibits symmetrical breakdown and clamping behavior in both polarities, with no cathode band marking on the DO-214AB case.
What is the maximum clamping voltage for SMCJ36CHE3/57T under surge conditions?
The maximum clamping voltage (VC) for SMCJ36CHE3/57T is 58.1 V at 25.8 A peak pulse current (IPPM) with a 10/1000 µs waveform, as specified in the Electrical Characteristics table on page 2 of Vishay document 88394.
Does SMCJ36CHE3/57T meet automotive reliability standards?
Yes, SMCJ36CHE3/57T is AEC-Q101 qualified, verified per Vishay's documentation. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance-making it suitable for under-hood and chassis-mounted automotive applications.
How does the thermal performance of SMCJ36CHE3/57T affect PCB layout?
With RθJA = 75 °C/W, SMCJ36CHE3/57T requires minimum 8.0 mm × 8.0 mm copper pads per terminal for rated 1500 W pulse handling. Reducing pad area increases junction temperature, derating peak power per Figure 2 in the datasheet-so layout must follow Vishay's recommended mounting footprint.
