Product details
Overview
SMA5J36CA-M3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤58.1 V at 8.6 A IPPM - used in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning.
For engineers reviewing the SMA5J36CA-M3/61 datasheet, SMA5J36CA-M3/61 pinout, SMA5J36CA-M3/61 application, or SMA5J36CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 500 W 10/1000 µs surge rating, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports tight clamping under fast-rising transients.
The device is rated for TJ = -55 °C to +150 °C operation and meets MSL Level 1 per J-STD-020 (260 °C peak reflow). Thermal resistance is 80 °C/W junction-to-ambient (RθJA) and 25 °C/W junction-to-lead (RθJL), confirming suitability for compact PCB layouts with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse voltage before clamping begins; defines operating window for protected circuitry |
| VBR min/max | 40.0 V / 44.2 V at 1 mA - guaranteed breakdown threshold range ensuring consistent turn-on behavior across production lots |
| VC @ IPPM | 58.1 V at 8.6 A - clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by downstream ICs |
| PPPM | 500 W - peak pulse power handling per 10/1000 µs waveform; defines single-event surge energy capacity |
| ID @ VWM | <1.0 µA - reverse leakage current at stand-off voltage; critical for low-power sensor and battery-backed circuits |
| TJ max | +150 °C - maximum junction temperature; enables use in under-hood automotive and industrial environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking - bidirectional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no cathode band marking required for bidirectional types |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC, differential, or floating signal lines without polarity constraints |
| 500 W 10/1000 µs surge rating | Withstands high-energy transients common in automotive load-dump and industrial switching events |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ISO 7637-2 pulses and ESD. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt surge energy before it reaches sensitive analog front-ends. Use Value: Limits transient voltage to ≤58.1 V, preserving signal integrity and preventing latch-up in 3.3 V/5 V microcontrollers and ADCs. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against inductive kickback from solenoids and relays. IC Role / Device Role / Timing Role: Fast-response TVS placed across input terminals to absorb 500 W surges without degradation over repeated switching cycles. Use Value: Maintains system uptime by preventing false triggering and component damage during factory automation equipment operation. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from lightning-induced surges and cross-talk coupling on unshielded twisted pair. IC Role / Device Role / Timing Role: Primary-level surge suppression on secondary-side data lines, coordinated with GDT or MOV upstream. Use Value: Provides sub-60 V clamping compatible with 3.3 V PHY I/O rails, reducing need for additional series impedance or buffering. | Use Scenario: Secondary-side overvoltage protection on 5 V/12 V DC outputs of wall adapters and USB PD chargers. IC Role / Device Role / Timing Role: Fail-safe clamp that activates only during fault conditions (e.g., regulator failure), avoiding standby power loss. Use Value: Ensures <1.0 µA leakage at 36 V, eliminating measurable quiescent drain on battery-powered devices connected to adapter output. |
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-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3) | Preferred for commercial-grade non-automotive designs where halogen content is unrestricted | Select E3 when cost sensitivity outweighs halogen-free requirement; M3 required for automotive Tier 1 compliance |
| SMA5J36CAHM3_A/H | Identical electrical specs; adds AEC-Q101 qualification and enhanced reliability screening | Required for automotive under-hood or safety-critical ECUs; includes extended temperature and lifetime validation | Choose HM3 variant when full AEC-Q101 qualification is mandated - not a drop-in replacement for M3 in non-qualified systems |
Compared with SMA5J36CA-M3/61, the E3 version offers identical surge performance at lower cost for commercial use, while the HM3 variant adds automotive qualification and reliability testing - making it suitable for safety-critical deployments where M3's commercial-grade spec is insufficient.

FAQ
What does the "CA" suffix indicate in SMA5J36CA-M3/61?
The "CA" suffix in SMA5J36CA-M3/61 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., SMA5J36A), SMA5J36CA-M3/61 has no cathode marking and functions identically regardless of voltage polarity - ideal for protecting AC signals, differential buses, or floating nodes where polarity cannot be guaranteed.
Is SMA5J36CA-M3/61 AEC-Q101 qualified?
SMA5J36CA-M3/61 is not AEC-Q101 qualified; it is a commercial-grade halogen-free part. The AEC-Q101 qualified version is SMA5J36CAHM3_A/H, which includes additional stress testing and screening per automotive reliability standards. For automotive applications requiring formal qualification, SMA5J36CAHM3_A/H must be selected - SMA5J36CA-M3/61 remains suitable for industrial and consumer designs meeting commercial reliability requirements.
What is the clamping voltage of SMA5J36CA-M3/61 and why does it matter?
The clamping voltage (VC) of SMA5J36CA-M3/61 is 58.1 V at 8.6 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value represents the maximum voltage imposed on protected circuitry during a surge event. It matters because downstream components - such as microcontrollers, transceivers, or sensors - must tolerate this voltage level without damage or malfunction; exceeding their absolute maximum ratings risks permanent failure.
How does the M3 suffix differ from E3 in SMA5J36CA-M3/61?
The M3 suffix in SMA5J36CA-M3/61 indicates halogen-free, RoHS-compliant construction, whereas E3 denotes RoHS-compliant but not halogen-free. Both share identical electrical characteristics and packaging, but M3 meets stricter environmental mandates (e.g., JEDEC JS709, IEC 61249-2-21) required by many automotive and green-electronics programs. SMA5J36CA-M3/61 is preferred where halogen content restrictions apply.
Can SMA5J36CA-M3/61 be used in place of SMA5J36A-M3/61?
No - SMA5J36CA-M3/61 is bidirectional, while SMA5J36A-M3/61 is unidirectional and features a cathode band marking. Substituting them requires verifying circuit topology: SMA5J36CA-M3/61 works on AC or polarity-agnostic lines, but SMA5J36A-M3/61 is required for DC circuits where reverse blocking is needed. Using SMA5J36CA-M3/61 in a unidirectional design may allow unintended conduction during normal operation.
