Product details
Overview
SMA5J36AHE3/5A 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 at 1 mA), 500 W peak pulse power (10/1000 μs), 8.6 A clamping current (IPPM), and 58.1 V maximum clamping voltage (VC) - deployed in automotive sensor interfaces and industrial power supply rails.
For engineers reviewing the SMA5J36AHE3/5A datasheet, SMA5J36AHE3/5A pinout, SMA5J36AHE3/5A application, or SMA5J36AHE3/5A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HE3 suffix), RoHS compliance, 150 °C junction temperature rating, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 μA leakage at 36 V), but triggers into low-impedance conduction when transients exceed VBR, limiting downstream voltage to ≤58.1 V at 8.6 A. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns).
Rated for 500 W peak pulse power per 10/1000 μs waveform and 40 A non-repetitive forward surge (8.3 ms half-sine), it sustains operation from –55 °C to +150 °C with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W - optimized for surface-mount PCB layouts with defined pad dimensions per DO-214AC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC/AC bias limit for protected line. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - guaranteed breakdown range ensures reliable turn-on margin above VWM with minimal tolerance spread. |
| VC @ IPPM | 58.1 V at 8.6 A - clamping voltage during 500 W surge; determines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 500 W - peak pulse power handling per 10/1000 μs waveform; enables robust protection against ISO 7637-2 Load Dump and IEC 61000-4-5 surges. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMA (DO-214AC) - standardized surface-mount outline with cathode band marking; compatible with J-STD-020 MSL Level 1 reflow (260 °C peak). |
Pinout & Package
Package: SMA (DO-214AC) - molded plastic case with matte tin-plated leads, UL 94 V-0 rated, 0.208" × 0.157" footprint, cathode indicated by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes shunt path during overvoltage events. |
| Cathode | High-side input terminal | Connected to protected line (e.g., 36 V rail or sensor output); polarity-sensitive - reverse connection disables protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature, reduces parameter drift, and improves reliability vs. epoxy-passivated alternatives. |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving clamping precision for sensitive 3.3 V or 5 V logic interfaces. |
| MSL Level 1 (260 °C) | Enables single-reflow assembly without moisture sensitivity concerns; eliminates bake-out requirement prior to SMT placement. |
Applications
| Automotive Sensor Protection | Industrial Power Supply Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36A-M3/5A | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification; same HE3/M3 suffix structure but HM3 denotes halogen-free. | No functional difference in protection performance; selected when halogen-free material compliance is mandated by OEM or regional regulations. | Choose SMA5J36A-M3/5A if halogen-free bill-of-materials is required; otherwise SMA5J36AHE3/5A satisfies standard automotive and industrial use cases. |
| SMA6J36AHE3/5A | 600 W peak pulse power rating (vs. 500 W); same VWM/VBR/VC; larger junction area increases surge margin but requires identical SMA footprint. | Used where higher surge immunity is needed (e.g., 120 J IEC 61000-4-5 testing), though not AEC-Q101 qualified in HE3 version per documented part numbering. | Select SMA6J36AHE3/5A only when 600 W capability is explicitly required and AEC-Q101 is not mandatory; SMA5J36AHE3/5A remains optimal for qualified automotive designs. |
Compared with SMA5J36A-M3/5A, SMA5J36AHE3/5A offers identical surge protection with standard RoHS compliance, while SMA6J36AHE3/5A trades qualification for higher power handling - making SMA5J36AHE3/5A the balanced choice for AEC-Q101–required 36 V systems needing proven reliability and manufacturability.

FAQ
What is the polarity configuration of the SMA5J36AHE3/5A?
The SMA5J36AHE3/5A is a unidirectional TVS diode: its cathode is marked by a black band on the SMA package body, and it conducts only when the cathode is biased positive relative to the anode. This configuration provides asymmetric clamping ideal for DC power rails and single-polarity signal lines - unlike bidirectional variants (e.g., SMA5J36CA) which protect AC or differential signals.
Does the SMA5J36AHE3/5A meet AEC-Q101 qualification?
Yes, the SMA5J36AHE3/5A is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code - indicating RoHS-compliant construction plus full stress testing per automotive reliability standards. This qualification covers temperature cycling, humidity testing, mechanical shock, and surge endurance, making SMA5J36AHE3/5A suitable for under-hood and safety-critical ECU applications.
What is the maximum clamping voltage of the SMA5J36AHE3/5A at rated surge current?
The SMA5J36AHE3/5A has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPPM) of 8.6 A, measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 500 W transient event - critical for ensuring downstream components remain within absolute maximum ratings.
Can the SMA5J36AHE3/5A be used in bidirectional signal protection?
No, the SMA5J36AHE3/5A is unidirectional and unsuitable for bidirectional signal lines such as RS-485, CAN, or USB data pairs. For those applications, bidirectional variants like SMA5J36CA must be used - they exhibit symmetric clamping in both directions and lack polarity marking. Using SMA5J36AHE3/5A on AC-coupled or differential lines risks improper conduction and protection failure.
What is the thermal resistance of the SMA5J36AHE3/5A in standard mounting conditions?
The SMA5J36AHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W when mounted on 0.2" × 0.2" copper pads per JEDEC standards. These values assume no additional heatsinking and define safe power derating above 25 °C ambient - essential for thermal design in enclosed industrial enclosures or automotive junction boxes.
