Product details
Overview
SMA5J36CA-M3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 μs), clamping voltage of 58.1 V at 8.6 A IPPM, and operates from –55 °C to +150 °C - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J36CA-M3/5A datasheet, SMA5J36CA-M3/5A pinout, SMA5J36CA-M3/5A application, or SMA5J36CA-M3/5A equivalent, key selection criteria include bidirectional clamping capability, halogen-free RoHS compliance (M3 suffix), 500 W surge rating, junction-to-lead thermal resistance of 25 °C/W, and AEC-Q101 qualification eligibility via HM3 variant.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical breakdown behavior ensures identical clamping in both polarities, with VBR tolerance ±5% and ID ≤1.0 μA at VWM.
Thermally, it delivers 500 W peak pulse power when mounted on 5.0 mm × 5.0 mm copper pads, derating linearly above 25 °C per Fig. 2, and maintains safe operation up to TJ = 150 °C with RθJA = 80 °C/W and RθJL = 25 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min / max | 40.0 V / 44.2 V - breakdown occurs within this range at 1 mA test current, ensuring predictable turn-on |
| VC @ IPPM | 58.1 V at 8.6 A - clamped voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 500 W - peak transient energy absorption capability under standardized waveform |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMA (DO-214AC) - surface-mount package with 2.54 mm lead pitch, UL 94 V-0 rated molding compound |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix), JESD201 Class 2 whisker resistant, MSL Level 1 |
Pinout & Package

| Low RθJL = 25 °C/W | Supports higher sustained surge repetition rates by efficiently transferring heat to PCB copper |
| AEC-Q101 qualification path | HM3 variant available for automotive applications requiring validated reliability per stress test schedule |
Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, responding within <1 ns to transients exceeding 36 V. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs while maintaining signal integrity below VWM. |
Use Scenario: Safeguarding PLC digital input modules against induced surges from relay coil switching and motor drive noise. IC Role / Device Role / Timing Role: Primary surge suppression device across 24 V DC input terminals, shunting >500 W transients to chassis ground. Use Value: Eliminates need for external series impedance or secondary clamping stages due to low VC and fast response. |
| Telecom Line Interface | Consumer USB/Display Port ESD Protection |
Use Scenario: Shielding RS-485/RS-422 differential pairs in base station backhaul equipment exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Common-mode TVS pair (one per line) referenced to ground, activated symmetrically during overvoltage events. Use Value: Maintains signal common-mode range while clamping differential spikes to <58.1 V, preserving receiver margin. |
Use Scenario: Board-level ESD protection for HDMI, USB 2.0, or DisplayPort connectors in set-top boxes and monitors. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) bidirectional clamp placed directly at connector pins to divert IEC 61000-4-2 ±15 kV contact discharge. Use Value: Prevents data corruption and port IC failure without degrading high-speed signal rise times. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CA-E3/5A | Same electrical specs; RoHS-compliant but contains brominated flame retardants (non-halogen-free) | Approved for commercial-grade industrial use; not qualified for halogen-free requirements in EU automotive programs | Select E3 if halogen content is unrestricted and cost sensitivity outweighs material compliance mandates |
| SMA5J36CAHM3_A/I | Identical TVS parameters plus full AEC-Q101 qualification (HTOL, TC, UHAST, etc.) and halogen-free construction | Required for automotive front-end modules, ADAS sensors, and infotainment systems subject to OEM PPAP | Choose HM3 variant when automotive qualification and halogen-free status are mandatory |
Compared with SMA5J36CA-M3/5A, the E3 version offers identical surge performance at lower cost but lacks halogen-free certification, while the HM3 variant adds AEC-Q101 validation and extended reliability testing - making it suitable for safety-critical automotive deployment where M3 meets commercial/halogen-free needs.

FAQ
What does the "CA" suffix mean in SMA5J36CA-M3/5A?
The "CA" suffix in SMA5J36CA-M3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage clamping in both forward and reverse directions. This eliminates polarity concerns during placement and enables use on AC-coupled or floating signal paths, unlike unidirectional variants (e.g., SMA5J36A) that require cathode alignment.
Is SMA5J36CA-M3/5A halogen-free and RoHS-compliant?
Yes, SMA5J36CA-M3/5A is both halogen-free and RoHS-compliant, as confirmed by the "M3" suffix per Vishay's ordering nomenclature. It meets JEDEC J-STD-020 MSL Level 1, JESD201 Class 2 whisker resistance, and UL 94 V-0 flammability standards - suitable for environmentally regulated industrial and consumer applications.
What is the clamping voltage of SMA5J36CA-M3/5A under surge conditions?
The clamping voltage (VC) of SMA5J36CA-M3/5A is 58.1 V at 8.6 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the maximum voltage imposed on protected circuitry during a surge event and is guaranteed across the full operating temperature range.
Can SMA5J36CA-M3/5A be used in automotive applications?
SMA5J36CA-M3/5A itself is commercial-grade; however, the pin-compatible HM3 variant (e.g., SMA5J36CAHM3_A/I) is AEC-Q101 qualified. For non-safety-critical automotive subsystems where halogen-free compliance is required but formal qualification is not mandated, SMA5J36CA-M3/5A may be deployed with system-level validation.
What is the thermal resistance from junction to lead (RθJL) for SMA5J36CA-M3/5A?
The typical thermal resistance from junction to lead (RθJL) for SMA5J36CA-M3/5A is 25 °C/W, as specified in the Vishay datasheet. This low value supports efficient heat transfer to the PCB copper land pattern, enabling reliable operation during repetitive surge events without excessive junction temperature rise.
