Product details
Overview
SMCJ36AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 µs waveform. It clamps transients to ≤58.1 V at 25.8 A peak current and operates across –55 °C to +150 °C junction temperature, targeting automotive-grade ESD and load-dump protection in power rails and sensor interfaces.
For engineers reviewing the SMCJ36AHE3_A/I datasheet, SMCJ36AHE3_A/I pinout, SMCJ36AHE3_A/I application, or SMCJ36AHE3_A/I equivalent, this AEC-Q101 qualified device delivers verified clamping performance, low incremental surge resistance, and RoHS-compliant matte tin-plated leads-key selection criteria for industrial motor drives, automotive body control modules, and 24 V DC power input stages.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages induced by inductive switching, ESD events, or lightning surges. Its unidirectional polarity features a cathode band marking and exhibits 1.0 µA max reverse leakage at 36 V standoff, enabling low-power standby compatibility.
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and achieves thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads-critical for sustained surge handling without thermal runaway in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 36 V - Maximum continuous reverse operating voltage before clamping initiates; sets threshold for 24 V system rail protection. |
| VBR (Breakdown Voltage) | 40.0–44.2 V at 1.0 mA - Confirmed minimum/maximum avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | ≤58.1 V at IPPM = 25.8 A - Measured maximum voltage during 1500 W surge; defines worst-case stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 1500 W at 10/1000 µs - Validated energy-handling capability per IEC 61000-4-5 Level 4; supports robust front-end protection. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated placement. |
| AEC-Q101 Qualified | Yes - Certified for automotive electronic systems per stress test requirements including HTOL, TCT, and ESD HBM/MM. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line (e.g., 24 V rail); conducts surge current to ground when voltage exceeds VBR. |
| Anode | Reference node | Typically tied to system ground; completes conduction path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tighter clamping (VC − VBR ≈ 17.9 V), reducing voltage overshoot stress on downstream MOSFETs or microcontrollers. |
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress, critical for automotive 15-year service life. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow at 260 °C peak, eliminating moisture sensitivity concerns in high-volume SMT assembly. |
| AEC-Q101 qualification | Validates suitability for automotive applications including BCM, ADAS sensors, and infotainment power supplies without additional qualification effort. |
| RoHS-compliant & halogen-free option available | Meets global environmental compliance mandates (e.g., EU RoHS, JEDEC JS709) while maintaining identical electrical performance. |
Applications

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/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range. | Restricted to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4. | Select only for space-constrained consumer electronics with <500 W surge exposure. |
| SMCJ36CAHE3_A/I | Bidirectional variant; identical VWM/VBR/PPPM but symmetric clamping in both polarities. | Required for AC-coupled signal lines or differential buses where reverse polarity transients occur. | Choose when protecting RS-485, CAN, or audio lines with bidirectional voltage excursions. |
Compared with SMAJ36AHE3_A/I and SMCJ36CAHE3_A/I, the SMCJ36AHE3_A/I uniquely balances 1500 W surge capacity, AEC-Q101 qualification, and unidirectional efficiency-making it the optimal choice for high-reliability 24 V DC power rail protection where polarity is fixed and energy levels exceed 1 kW.

FAQ
What is the clamping voltage of the SMCJ36AHE3_A/I at its rated peak pulse current?
The SMCJ36AHE3_A/I has a maximum clamping voltage (VC) of 58.1 V when subjected to its peak pulse current (IPPM) of 25.8 A under a 10/1000 µs waveform. This value is measured and guaranteed per the Vishay datasheet (Document Number: 88394, Rev. 09-Jan-2024), and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The SMCJ36AHE3_A/I maintains this clamping performance across its operational temperature range.
Is the SMCJ36AHE3_A/I suitable for automotive applications?
Yes, the SMCJ36AHE3_A/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet's Mechanical Data section and Ordering Information table. Its qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD (HBM/MM), making it suitable for under-hood and cabin automotive systems such as body control modules and ADAS power supplies. The SMCJ36AHE3_A/I also meets MSL Level 1 for reflow compatibility in automotive PCB assembly.
What does the "HE3" suffix indicate in SMCJ36AHE3_A/I?
The "HE3" suffix in SMCJ36AHE3_A/I denotes a RoHS-compliant and AEC-Q101 qualified version with matte tin-plated leads, per Vishay's ordering nomenclature. The "H" indicates the tape-and-reel packaging option (3500 units per 13″ reel), and "A/I" specifies the revision code and delivery mode. This distinguishes the SMCJ36AHE3_A/I from commercial-grade variants like SMCJ36A-E3/57T and confirms its suitability for automotive production use.
How does the SMCJ36AHE3_A/I differ from the bidirectional SMCJ36CAHE3_A/I?
The SMCJ36AHE3_A/I is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where surge polarity is known (e.g., 24 V supply to ground). In contrast, the SMCJ36CAHE3_A/I is bidirectional-lacking polarity marking-and provides symmetric clamping for AC signals or differential lines like RS-485. Both share identical VWM (36 V), VBR (40.0–44.2 V), and PPPM (1500 W), but the SMCJ36AHE3_A/I offers lower leakage and higher forward surge capability (200 A IFSM).
What is the thermal resistance of the SMCJ36AHE3_A/I, and how does it affect layout design?
The SMCJ36AHE3_A/I 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 Thermal Characteristics table. This value guides PCB layout: to maintain TJ ≤ 150 °C during repeated surges, designers must ensure adequate copper area and avoid excessive trace length between the SMCJ36AHE3_A/I anode/cathode and their respective ground/power planes. Smaller pads increase RθJA and risk thermal failure.
