Product details
Overview
SMCJ36CA001HE3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 58.1 V maximum clamping voltage at 25.8 A peak pulse current, 36 V standoff voltage, and -55 °C to +150 °C operating temperature range - used for protecting automotive sensor signal lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the SMCJ36CA001HE3/9AT datasheet, SMCJ36CA001HE3/9AT pinout, SMCJ36CA001HE3/9AT application, or SMCJ36CA001HE3/9AT equivalent, this part delivers AEC-Q101 qualified surge protection with bidirectional symmetry, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial designs requiring robust ESD and lightning transient immunity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage VBR min/max of 40.0 V / 44.2 V at 1 mA test current, standoff voltage VWM = 36 V, and reverse leakage ID ≤ 1.0 μA at VWM. Its clamping behavior is defined by a 10/1000 μs waveform, achieving VC = 58.1 V at IPPM = 25.8 A.
Thermal performance includes RθJA = 75 °C/W (junction-to-ambient, typical) and RθJL = 15 °C/W (junction-to-lead), enabling reliable operation under repetitive surge conditions when mounted on 8.0 mm × 8.0 mm copper pads. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
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 |
|---|---|---|---|
| SAC36CA-E3/9AT | Same VWM (36 V) and VC (58 V), but lower PPPM = 600 W and non-AEC-Q101 rated | Limited to commercial-grade consumer or office equipment; not suitable for automotive or harsh industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| SMCJ36CAHM3/9AT | Identical electrical specs and AEC-Q101 qualification, but halogen-free molding compound and HM3 suffix | Required for RoHS-compliant, halogen-free BOMs in EU automotive programs (e.g., VW TL 813) | Choose when halogen-free compliance is mandated and HE3/HE3-based supply chain is unavailable |
Compared with SMCJ36CA001HE3/9AT, SAC36CA-E3/9AT offers reduced surge capability for cost-driven non-automotive use, while SMCJ36CAHM3/9AT provides identical protection with halogen-free materials - making the HE3 variant optimal for general AEC-Q101 applications where halogen content is unrestricted.

FAQ
What is the clamping voltage of SMCJ36CA001HE3/9AT at its rated peak pulse current?
The SMCJ36CA001HE3/9AT has a maximum clamping voltage VC of 58.1 V at IPPM = 25.8 A using a 10/1000 μs waveform. This value is measured under standardized test conditions with 8.0 mm × 8.0 mm copper pads per terminal and represents the upper bound voltage imposed on protected circuitry during full-rated surge events. The SMCJ36CA001HE3/9AT maintains this clamping performance across its full operating temperature range.
Is SMCJ36CA001HE3/9AT suitable for automotive applications?
Yes, SMCJ36CA001HE3/9AT is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and validation across temperature cycling, high-temperature reverse bias, and ESD tests per AEC standard. The SMCJ36CA001HE3/9AT meets requirements for under-hood and cabin-mounted modules operating from -55 °C to +150 °C.
How does the bidirectional configuration of SMCJ36CA001HE3/9AT affect its circuit implementation?
The bidirectional configuration of SMCJ36CA001HE3/9AT eliminates polarity marking and enables direct placement across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (RS-485, CAN), AC-coupled lines, or floating grounds. Unlike unidirectional TVS diodes, the SMCJ36CA001HE3/9AT conducts identically for both positive and negative transients, simplifying layout and eliminating risk of reverse installation. No external components or orientation checks are needed.
What is the standoff voltage rating of SMCJ36CA001HE3/9AT, and how does it relate to system operating voltage?
The standoff voltage VWM of SMCJ36CA001HE3/9AT is 36 V - the maximum DC or continuous peak voltage the device will block without entering avalanche conduction. It is selected to be ≥10–15% above the system's normal operating voltage (e.g., 24 V automotive battery nominal) to prevent leakage or false triggering during transients like cranking dips or ripple. The SMCJ36CA001HE3/9AT remains fully inactive below 36 V, ensuring zero interference with normal circuit operation.
Does SMCJ36CA001HE3/9AT require heatsinking in typical applications?
No dedicated heatsink is required for SMCJ36CA001HE3/9AT in single-event surge suppression, as its 1500 W rating applies to non-repetitive pulses. However, thermal performance depends on PCB copper area: the datasheet specifies derating curves based on junction temperature rise, with RθJA = 75 °C/W typical when mounted on minimum recommended 8.0 mm × 8.0 mm pads. For repetitive surge environments, thermal design must ensure TJ stays ≤150 °C - the SMCJ36CA001HE3/9AT's absolute maximum junction temperature.
