Product details
Overview
SMA5J36CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 500 W peak pulse power, 36 V standoff voltage (VWM), and clamping voltage of 58.1 V at 8.6 A IPPM. It provides robust ESD and surge protection for automotive sensor signal lines, industrial I/O interfaces, and power supply rails.
For engineers reviewing the SMA5J36CAHE3_A/H datasheet, SMA5J36CAHE3_A/H pinout, SMA5J36CAHE3_A/H application, or SMA5J36CAHE3_A/H equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging an avalanche breakdown mechanism with glass-passivated junction. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating need for polarity-aware layout.
Designed for 10/1000 µs surge waveforms per ANSI/IEEE C62.35, it delivers stable clamping up to 58.1 V while maintaining <1 µA reverse leakage at 36 V, and achieves thermal resistance of 25 °C/W junction-to-lead under recommended copper pad mounting.
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, defining turn-on threshold |
| VC @ IPPM | 58.1 V - Clamped voltage seen by protected circuit at 8.6 A peak surge current |
| PPPM | 500 W - Peak transient energy absorption capability under standardized 10/1000 µs waveform |
| TJ max. | +150 °C - Maximum allowable junction temperature supports under-hood automotive use |
| Polarity | Bidirectional - Symmetric protection without polarity marking; no cathode band on package |
| MSL Level | Level 1 (260 °C peak) - Compatible with standard lead-free reflow profiles without preconditioning |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. No polarity marking - bidirectional operation confirmed.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector entry point to shunt surge energy before reaching signal conditioning circuitry. Use Value: Maintains signal integrity by limiting transient voltage to ≤58.1 V, preventing latch-up or damage to 3.3 V/5 V microcontrollers and ADC front-ends. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring surges and ground-loop transients in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional clamping element across isolated 24 V DC input lines, absorbing ±1 kV EFT bursts per IEC 61000-4-4. Use Value: Eliminates need for external polarity selection; symmetric response ensures equal protection for positive and negative transients on shared signal-return paths. |
| DC Power Rail Protection | Telecom Interface Protection |
Use Scenario: Secondary surge suppression on 36 V nominal DC power distribution networks in railway signaling and solar charge controllers. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after primary MOV or GDT stage to refine clamping level and handle residual fast-rising spikes. Use Value: Withstands repeated 500 W surges while holding rail voltage below 58.1 V, preserving MOSFET gate drivers and DC-DC controller ICs. | Use Scenario: Protecting RS-485 transceiver pins in base station remote radio units exposed to lightning-induced surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) bidirectional clamp integrated into PCB-level surge protection network near connector. Use Value: Fast response time (<1 ns) and symmetrical clamping preserve signal edge integrity on full-duplex differential data lines up to 10 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CAHM3_A/H | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU public transport) | Direct substitution if halogen-free requirement applies; same footprint, thermal, and electrical behavior |
| SMA6J36CAHE3_A/H | 600 W PPPM rating (vs. 500 W); same VWM, VC, and package; higher IPPM (9.7 A vs. 8.6 A) | Higher energy handling enables longer surge duration immunity or tighter design margins in harsh environments | Preferred when system-level surge tests exceed IEC 61000-4-5 Level 4; requires verification of board-level thermal dissipation |
Compared with SMA5J36CAHE3_A/H, the SMA5J36CAHM3_A/H offers identical protection performance with halogen-free construction, while the SMA6J36CAHE3_A/H increases peak power handling by 20 %-enabling robustness against extended 10/1000 µs surges without changing PCB layout or mounting.

FAQ
What does the "CA" suffix indicate in SMA5J36CAHE3_A/H?
The "CA" suffix in SMA5J36CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., SMA5J36A), SMA5J36CAHE3_A/H has no cathode marking and clamps equally for positive and negative transients-critical for AC-coupled or floating signal lines.
Is SMA5J36CAHE3_A/H qualified for automotive applications?
Yes, SMA5J36CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling-ensuring reliability in under-hood automotive environments up to +150 °C junction temperature.
What is the maximum clamping voltage for SMA5J36CAHE3_A/H under surge conditions?
The maximum clamping voltage for SMA5J36CAHE3_A/H is 58.1 V, measured at its rated peak pulse current (IPPM) of 8.6 A using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events.
How does the SMA (DO-214AC) package of SMA5J36CAHE3_A/H affect thermal performance?
The SMA (DO-214AC) package of SMA5J36CAHE3_A/H achieves a typical junction-to-lead thermal resistance (RθJL) of 25 °C/W when mounted on minimum recommended copper pads (0.2" × 0.2"). This enables effective heat dissipation during repetitive surge events, supporting reliable operation at TA ≤ +125 °C without derating in most industrial PCB layouts.
Can SMA5J36CAHE3_A/H replace unidirectional TVS diodes like SMA5J36AHE3_A/H?
No-SMA5J36CAHE3_A/H is not a drop-in replacement for unidirectional SMA5J36AHE3_A/H due to fundamental polarity differences. While both share identical VWM (36 V) and package, SMA5J36CAHE3_A/H lacks a cathode band and conducts symmetrically; substituting it in a unidirectional circuit may cause unintended forward conduction or fail to meet system-level polarity-specific protection requirements.
