Product details
Overview
SMA5J36CAHM3_A/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 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 (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 SMA5J36CAHM3_A/H datasheet, SMA5J36CAHM3_A/H pinout, SMA5J36CAHM3_A/H application, or SMA5J36CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (via HM3 suffix), 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression using a glass-passivated junction. Its bidirectional symmetry ensures identical electrical characteristics in both polarities, with clamping behavior defined by the 10/1000 μs waveform standard per ANSI/IEEE C62.35.
Thermal performance is characterized by RθJA = 80 °C/W and RθJL = 25 °C/W, enabling reliable operation up to TJ = 150 °C when mounted per recommended pad layout. The HM3 suffix confirms halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance and MSL Level 1 rating (260 °C peak reflow).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CAHE3_A/H | RoHS-compliant but not halogen-free; lacks JESD 201 Class 2 whisker resistance certification | Approved for commercial-grade automotive modules where halogen-free requirement is waived | Select when cost sensitivity outweighs halogen-free mandate and whisker risk is mitigated by board-level controls |
| SMA6J36CA-M3 | 600 W PPPM rating, higher IPPM (9.7 A), larger thermal resistance (RθJA = 85 °C/W) | Better suited for higher-energy surges but requires larger pad area and tighter thermal management | Choose for designs needing margin beyond 500 W, accepting increased footprint and layout constraints |
Compared with SMA5J36CAHM3_A/H, SMA5J36CAHE3_A/H offers identical electrical specs but reduced material compliance, while SMA6J36CA-M3 delivers higher surge capacity at the expense of thermal efficiency and board space - making SMA5J36CAHM3_A/H optimal for AEC-Q101–mandated, space-constrained automotive and industrial applications requiring halogen-free construction.

FAQ
What is the clamping voltage of the SMA5J36CAHM3_A/H under a 500 W transient?
The SMA5J36CAHM3_A/H clamps to a maximum of 58.1 V when subjected to its rated 500 W peak pulse power with a 10/1000 μs waveform. This value is measured at an IPPM of 8.6 A and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream ICs remain within safe operating limits.
Is the SMA5J36CAHM3_A/H suitable for automotive applications?
Yes, the SMA5J36CAHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix indicating halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance. It is explicitly intended for automotive use cases including sensor interfaces, body control modules, and infotainment system power rails where reliability under thermal and mechanical stress is critical.
Does the SMA5J36CAHM3_A/H have polarity markings?
No, the SMA5J36CAHM3_A/H does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMA5J36A), this device has symmetrical electrical characteristics in both directions and omits the cathode band per Vishay's mechanical specification for CA-suffix parts.
What is the thermal resistance of the SMA5J36CAHM3_A/H?
The SMA5J36CAHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and a junction-to-lead resistance (RθJL) of 25 °C/W, measured when mounted on the minimum recommended 5.0 mm × 5.0 mm copper pads per datasheet Figure 2. These values govern derating curves for sustained surge duty cycles above 25 °C ambient.
How does the HM3 suffix differ from the HE3 suffix in SMA5J36CAHM3_A/H?
The HM3 suffix in SMA5J36CAHM3_A/H denotes halogen-free, RoHS-compliant, and AEC-Q101–qualified construction with JESD 201 Class 2 whisker resistance, whereas HE3 indicates RoHS-compliance and AEC-Q101 qualification without halogen-free assurance. Both share identical electrical specifications, but HM3 meets stricter environmental and reliability mandates for modern automotive platforms.
