Product details
Overview
SMA5J13HE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode (TVS) in DO-214AC (SMA) package, designed for clamping inductive load switching transients and lightning-induced surges on power rails and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), 500 W peak pulse power (10/1000 µs), 23.3 A peak pulse current (IPPM), and 21.5 V maximum clamping voltage (VC) at IPPM, with AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J13HE3/61 datasheet, SMA5J13HE3/61 pinout, SMA5J13HE3/61 application, or SMA5J13HE3/61 equivalent, key selection criteria include its unidirectional polarity, 150 °C max junction temperature, RoHS-compliant matte tin-plated leads, MSL Level 1 rating, and suitability for high-reliability automotive power rail protection where fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive surge stress are required.
Technical Context
This TVS diode operates as a voltage-clamping device in series with the protected line, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable leakage performance and long-term reliability under thermal cycling.
Designed for surface-mount placement on PCBs with minimum 0.2" × 0.2" copper pads per terminal, it delivers 500 W surge handling per JEDEC-standard 10/1000 µs waveform while maintaining low RθJA = 80 °C/W and RθJL = 25 °C/W for effective thermal management in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (min/max) | 14.4 V / 15.9 V - Breakdown voltage range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 21.5 V - Clamped voltage at 23.3 A peak pulse; determines maximum overvoltage seen by downstream ICs during surge. |
| PPPM | 500 W - Peak pulse power dissipation capability with 10/1000 µs waveform; validates robustness against ISO 7637-2 Pulse 1/2a/5a events. |
| IPPM | 23.3 A - Peak pulse current corresponding to VC; used to size PCB trace width and verify layout survivability. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| MSL Level | Level 1 (per J-STD-020) - Supports standard reflow profiles up to 260 °C peak without moisture-related failure. |

Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable reverse leakage (<1 µA at VWM) and long-term reliability under thermal/humidity stress. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics applications requiring zero-defect reliability. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive MOSFETs and microcontrollers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13A-E3/61 | Same electrical specs (VWM = 13 V, VC = 21.5 V), but commercial-grade (non-AEC-Q101 qualified); HE3 suffix indicates AEC-Q101, E3 does not. | Not suitable for automotive under-hood use; acceptable for industrial/commercial power supplies. | Select SMA5J13HE3/61 when AEC-Q101 qualification and extended temperature validation are mandatory. |
| SMC5J13AHE3/61 | Same VWM/VC, but larger DO-214AB (SMC) package; higher IFSM (100 A vs. 40 A) and lower RθJA (50 °C/W). | Requires larger PCB footprint; preferred for high-surge industrial motor drives where 40 A IFSM is marginal. | Choose SMA5J13HE3/61 for space-constrained automotive modules; SMC5J13AHE3/61 where surge margin and thermal headroom are critical. |
Compared with SMA5J13A-E3/61, SMA5J13HE3/61 adds automotive-grade reliability validation and whisker resistance; compared with SMC5J13AHE3/61, it trades footprint and surge margin for board area efficiency and cost-making it optimal for AEC-Q101-compliant, space-limited 12 V rail protection.

FAQ
What is the polarity configuration of SMA5J13HE3/61?
SMA5J13HE3/61 is a unidirectional TVS diode, meaning it functions as a reverse-biased zener-like clamp. The cathode is marked with a band on the DO-214AC package body; anode connects to ground, cathode to the protected line. It does not conduct forward current beyond typical diode levels and is not intended for bidirectional surge suppression.
Does SMA5J13HE3/61 meet automotive qualification standards?
Yes, SMA5J13HE3/61 is AEC-Q101 qualified, as confirmed by Vishay's documentation and the "HE3" suffix designation. This qualification covers stress tests including temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-validating its suitability for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of SMA5J13HE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J13HE3/61 is 21.5 V at its rated peak pulse current (IPPM) of 23.3 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does the HE3 suffix differ from E3 in SMA5J13HE3/61?
The "HE3" suffix in SMA5J13HE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. In contrast, "E3" alone (e.g., SMA5J13A-E3/61) indicates RoHS compliance but no AEC-Q101 validation or enhanced whisker testing-making HE3 mandatory for automotive deployment.
What is the thermal resistance profile of SMA5J13HE3/61?
SMA5J13HE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured on standard 0.2" × 0.2" copper pads. These values guide thermal design for sustained surge duty cycles and ensure safe operation up to +150 °C junction temperature.
