Product details
Overview
SMA5J36C-E3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients 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 to ≤58.1 V at 8.6 A peak pulse current (IPPM), protecting sensitive ICs and MOSFETs in automotive and industrial systems.
For engineers reviewing the SMA5J36C-E3/5A datasheet, SMA5J36C-E3/5A pinout, SMA5J36C-E3/5A application, or SMA5J36C-E3/5A equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 80 °C/W), DO-214AC mechanical dimensions, and direct alternatives for surge protection design-in.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with no polarity marking on the case. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and lightning-induced transients per IEC 61000-4-2/4-5.
Rated for -55 °C to +150 °C junction temperature, it meets MSL Level 1 (260 °C reflow peak) and is qualified to AEC-Q101 for automotive under-hood applications. The 500 W PPPM rating applies to 10/1000 µs waveform with derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 40.0 V / 44.2 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | ≤58.1 V - Clamped voltage at 8.6 A peak pulse ensures downstream devices stay below safe voltage limits |
| PPPM | 500 W - Sustains 10/1000 µs surge energy without failure; defines robustness against repetitive transients |
| ID @ VWM | ≤1.0 µA - Ultra-low leakage preserves signal integrity and minimizes standby power loss |
| RθJA | 80 °C/W - Thermal resistance determines required PCB copper area for reliable power dissipation |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CAHE3/5A | AEC-Q101 qualified variant with HE3 whisker-tested terminations; identical VWM/VBR/PPPM | Required for automotive production where whisker resistance class 2 (JESD 201) is mandated | Select when full automotive qualification traceability and enhanced plating reliability are mandatory |
| SMCJ36CA | Larger DO-214AB (SMC) package; same 36 V VWM but higher 1500 W PPPM and lower RθJA (30 °C/W) | Better suited for high-energy industrial surges where board space allows larger footprint | Choose when system-level surge tests exceed 500 W or thermal budget demands lower junction rise |
Compared with SMA5J36C-E3/5A, the HE3 variant adds whisker-test compliance without electrical change, while SMCJ36CA trades compact size for higher surge capacity and improved thermal performance-enabling selection based on qualification tier or energy requirement, not just voltage rating.

FAQ
What is the polarity configuration of SMA5J36C-E3/5A?
SMA5J36C-E3/5A is a bi-directional TVS diode with no polarity marking on the DO-214AC package body. It functions identically in both directions, making it suitable for AC-coupled lines or unidirectional rails where reverse transients may occur. This eliminates orientation errors during automated placement and simplifies schematic symbol usage compared to uni-directional variants like SMA5J36A-E3/5A.
Does SMA5J36C-E3/5A meet automotive qualification standards?
Yes, SMA5J36C-E3/5A is RoHS-compliant and manufactured to AEC-Q101 stress test requirements for transient voltage suppressors. While the base E3 suffix denotes commercial-grade qualification, its construction-including glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max-supports automotive under-hood use. For full production traceability, the HE3-suffixed variant SMA5J36CAHE3/5A is explicitly certified to AEC-Q101.
What is the maximum clamping voltage for SMA5J36C-E3/5A under surge conditions?
The maximum clamping voltage (VC) for SMA5J36C-E3/5A is 58.1 V, measured at the peak pulse current (IPPM) of 8.6 A using a 10/1000 µs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during standardized surge events, and is guaranteed across the full operating temperature range of -55 °C to +150 °C.
How does the thermal resistance of SMA5J36C-E3/5A affect PCB layout?
SMA5J36C-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on minimum recommended copper pads (0.2" × 0.2"). To maintain safe junction temperatures during 500 W surges, designers must allocate adequate copper area-typically ≥250 mm² per terminal-and avoid thermal isolation. Reduced pad area increases RθJA, risking thermal runaway during repetitive transients.
Can SMA5J36C-E3/5A replace SMA5J36A-E3/5A in existing designs?
No-SMA5J36C-E3/5A is bi-directional while SMA5J36A-E3/5A is uni-directional, with a cathode band marking and forward voltage drop (~3.5 V at 25 A). Swapping them risks incorrect clamping behavior on reverse-polarity transients or unintended conduction in DC-biased circuits. The "C" suffix explicitly denotes bi-directional functionality; substitution requires circuit review and layout verification.
