Product details
Overview
SMA5J36CAHM3/H 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 power rails.
For engineers reviewing the SMA5J36CAHM3/H datasheet, SMA5J36CAHM3/H pinout, SMA5J36CAHM3/H application, or SMA5J36CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, and thermal resistance (RθJA = 80 °C/W) under PCB pad-limited dissipation.
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 leakage (<1.0 μA at VWM) and fast response time (<1.0 ps) to ESD and lightning-induced surges.
Rated for 150 °C maximum junction temperature and MSL Level 1 (260 °C reflow), SMA5J36CAHM3/H supports automated SMT assembly and meets JESD201 Class 2 whisker resistance. The device uses a 10/1000 μs surge waveform standard per ANSI/IEEE C62.35 and derates linearly above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias window. |
| VBR min/max | 40.0 V / 44.2 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 58.1 V at 8.6 A - Clamped voltage under 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 500 W - Peak pulse power handling with 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; sets thermal design margin for PCB copper pad layout and airflow. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; guides heatsinking requirements. |
Pinout & Package

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 load dump and inductive switching spikes in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed at connector interface or IC input pins to shunt surge energy before it reaches sensitive analog front-ends. Use Value: Limits transient voltage to ≤58.1 V while maintaining <1.0 μA leakage - preserving signal integrity and enabling AEC-Q100-compliant system design. |
Use Scenario: Safeguarding digital and analog I/O channels on programmable logic controller (PLC) modules exposed to field wiring surges in factory automation environments. IC Role / Device Role / Timing Role: Primary surge suppression element across 24 V DC supply rails and isolated RS-485/RS-232 signal pairs. Use Value: Withstands 500 W peak pulses and operates up to +150 °C ambient - ensuring uptime in uncooled control cabinets. |
| Telecom Power Rail Protection | Consumer USB/Type-C Port Protection |
Use Scenario: Secondary-level surge protection on 48 V PoE (Power over Ethernet) injectors and splitters against induced lightning transients. IC Role / Device Role / Timing Role: Back-to-back TVS pair (or single bidirectional unit) placed between transformer secondary and DC-DC converter input. Use Value: Clamps 10/1000 μs surges to 58.1 V with 80 °C/W thermal resistance - compatible with compact PoE board layouts. |
Use Scenario: Overvoltage protection on VBUS and CC lines of USB Type-C receptacles in laptops and docking stations subject to hot-plug and ESD events. IC Role / Device Role / Timing Role: Standoff-rated TVS suppressing ±15 kV contact ESD (IEC 61000-4-2) and cable discharge events. Use Value: 36 V VWM avoids interference with 5 V/9 V/15 V/20 V PD profiles while delivering sub-nanosecond response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36CA | Same VWM (36 V), lower PPPM (400 W), higher VC (60.0 V at 8.3 A), non-AEC-Q101 rated | Commercial-grade only; not qualified for automotive underhood or chassis locations | Select when cost sensitivity outweighs AEC-Q101 requirement and 500 W surge margin is noncritical |
| ON Semiconductor 1.5SMC36CA | Same VWM (36 V), same PPPM (500 W), slightly higher VBR (40.1–44.4 V), MSL Level 1, but halogen-containing (non-HM3) | RoHS-compliant but not halogen-free; lacks automotive whisker test certification (JESD201 Class 2) | Choose if halogen-free mandate is waived and existing 1.5SMC footprint compatibility is required |
Compared with SMA5J36CAHM3/H, SMAJ36CA offers lower surge rating and no automotive qualification, while 1.5SMC36CA matches power but omits halogen-free and whisker-resistance validation - making SMA5J36CAHM3/H the sole option meeting full AEC-Q101 + halogen-free + 500 W spec.

FAQ
What does the "HM3" suffix mean in SMA5J36CAHM3/H?
The HM3 suffix in SMA5J36CAHM3/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms compliance with JESD201 Class 2 whisker resistance testing and maximum reflow temperature of 260 °C - essential for automotive under-hood and industrial control applications requiring long-term reliability.
Is SMA5J36CAHM3/H unidirectional or bidirectional?
SMA5J36CAHM3/H is a bidirectional TVS diode, as confirmed by the "CA" suffix in its part number and its symmetrical electrical characteristics in both polarities. It has no cathode band marking and provides identical clamping behavior whether surge polarity is positive or negative relative to ground.
What is the maximum clamping voltage for SMA5J36CAHM3/H under surge conditions?
The maximum clamping voltage (VC) for SMA5J36CAHM3/H is 58.1 V at 8.6 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a defined surge event.
Does SMA5J36CAHM3/H require a heatsink for 500 W surge handling?
No external heatsink is required for single-pulse 500 W operation, as SMA5J36CAHM3/H relies on PCB copper pad thermal mass. Its RθJA of 80 °C/W assumes mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - sufficient for transient dissipation without sustained power loading.
Can SMA5J36CAHM3/H replace SMAJ36CA in an existing design?
SMA5J36CAHM3/H is not a direct drop-in replacement for SMAJ36CA due to differences in packaging dimensions (SMA vs. DO-214AC is identical, but mechanical tolerances differ) and qualification status. While electrically similar, SMA5J36CAHM3/H adds AEC-Q101 and halogen-free compliance - redesign verification is recommended before substitution.
