Product details
Overview
SMA5J36AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 8.6 A peak pulse current (IPPM), and clamps to ≤58.1 V at rated surge. It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J36AHM3/I datasheet, SMA5J36AHM3/I pinout, SMA5J36AHM3/I application, or SMA5J36AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its VBR threshold, limiting transient overvoltages to ≤58.1 V at 8.6 A. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at 36 V).
Designed for 10/1000 µs surge waveforms per IEC 61000-4-5, it delivers 500 W peak pulse power with low incremental surge resistance and fast response time (<1 ns). Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead) under specified mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 36 V DC rails. |
| VBR (min/max) | 40.0 V / 44.2 V - Verified breakdown range at 1 mA test current; ensures predictable turn-on across production lot. |
| VC @ IPPM | ≤58.1 V - Clamped voltage during 500 W surge event; determines maximum stress imposed on protected downstream circuitry. |
| IPPM | 8.6 A - Peak surge current supported at 10/1000 µs waveform; directly correlates with energy handling (E = VC × IPPM × t). |
| TJ max | +150 °C - Maximum junction temperature rating; enables reliable operation in under-hood automotive and industrial environments. |
| Package | SMA (DO-214AC) - Surface-mount package with 2.54 mm lead pitch; compatible with J-STD-020 MSL Level 1 reflow (260 °C peak). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36AHE3/I | Same electrical specs and package, but RoHS-compliant commercial grade (not AEC-Q101 qualified); uses E3 suffix instead of HM3. | Lacks automotive qualification; suitable for industrial/commercial systems where AEC-Q101 is not mandated. | Select SMA5J36AHE3/I when cost sensitivity outweighs automotive reliability requirements and halogen-free is not required. |
| SMCJ36A | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VBR range; 10x higher IPPM (25.7 A) and lower VC (58.1 V → 58.1 V same, but at higher current). | Used where higher surge immunity (e.g., 4 kV/2 Ω combo wave) or longer surge duration is required; requires larger PCB footprint. | Choose SMCJ36A when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger package. |
Compared with SMA5J36AHM3/I, SMA5J36AHE3/I offers identical clamping performance without AEC-Q101 validation or halogen-free materials, while SMCJ36A provides triple the peak power rating in a physically larger package-making SMA5J36AHM3/I optimal for space-constrained automotive modules needing certified reliability.

FAQ
What is the polarity configuration of SMA5J36AHM3/I?
SMA5J36AHM3/I is a unidirectional TVS diode: the banded end is the cathode and must be connected to the protected line (e.g., 36 V rail), while the anode connects to ground. This configuration enables forward conduction only during negative transients and avalanche clamping during positive overvoltage events on the cathode side.
Does SMA5J36AHM3/I meet automotive qualification standards?
Yes, SMA5J36AHM3/I carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and fully qualified to AEC-Q101 for automotive applications. This includes stress testing for temperature cycling, high-temperature reverse bias, and ESD robustness-making SMA5J36AHM3/I suitable for under-hood and body electronics.
What is the maximum clamping voltage of SMA5J36AHM3/I at its rated surge current?
The maximum clamping voltage (VC) of SMA5J36AHM3/I is 58.1 V when subjected to its rated peak pulse current (IPPM) of 8.6 A under the standard 10/1000 µs waveform. This value is guaranteed across temperature and production lot, defining the upper voltage limit imposed on protected circuitry during surge events.
Can SMA5J36AHM3/I be used in bidirectional configurations?
No, SMA5J36AHM3/I is strictly unidirectional. For bidirectional transient suppression, Vishay specifies part numbers ending in "CA" (e.g., SMA5J36CA). Using SMA5J36AHM3/I in reverse-biased configurations outside its specified unidirectional operation risks failure due to lack of symmetrical breakdown characteristics.
What is the thermal resistance specification for SMA5J36AHM3/I under standard mounting conditions?
SMA5J36AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 25 °C/W, supporting accurate thermal modeling for systems operating up to +150 °C junction temperature.
