Product details
Overview
SMA5J5.0-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 54.3 V clamping voltage at 9.2 A peak surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J5.0-E3/5A datasheet, SMA5J5.0-E3/5A pinout, SMA5J5.0-E3/5A application, or SMA5J5.0-E3/5A equivalent, key selection criteria include unidirectional polarity, 800 µA max reverse leakage at VWM, 150 °C max junction temperature, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The SMA5J5.0-E3/5A operates as a silicon avalanche diode that enters controlled breakdown above its VBR threshold to clamp transient surges. Its glass-passivated junction ensures stable leakage and long-term reliability under repetitive stress.
It delivers 500 W peak pulse power per 10/1000 µs waveform with 54.3 V clamping voltage at 9.2 A, and exhibits low incremental surge resistance for minimal voltage overshoot during fast transients such as ESD or inductive switching events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0AHE3/5A | AEC-Q101 qualified; identical electrical specs; HE3 denotes enhanced whisker test (JESD 201 Class 2) | Required for automotive safety-critical modules where whisker growth risk must be minimized beyond Class 1A | Select SMA5J5.0AHE3/5A when full AEC-Q101 compliance documentation and extended whisker resistance are mandated. |
| SMCJ5.0A-E3/57T | Higher 1500 W PPPM; DO-214AB (SMC) package; 2.5× larger footprint; same VWM/VBR range | Suitable for higher-energy transients (e.g., 10/1000 µs surges >20 A) where board space allows larger package | Choose SMCJ5.0A-E3/57T only if system-level testing confirms need for >500 W surge handling and layout accommodates SMC outline. |
Compared with SMA5J5.0AHE3/5A, the SMA5J5.0-E3/5A offers identical clamping and surge performance but with Class 1A whisker resistance-sufficient for most commercial and non-safety automotive uses. Versus SMCJ5.0A-E3/57T, it trades lower power rating for compact DO-214AC size, enabling tighter routing in space-constrained 5 V rail protection.

FAQ
What is the polarity configuration of the SMA5J5.0-E3/5A?
The SMA5J5.0-E3/5A is a unidirectional transient voltage suppressor. Its cathode is marked by a band on the DO-214AC package body; it blocks reverse current up to 5.0 V and avalanches in the forward direction when voltage exceeds 6.4 V. This configuration suits DC power rail protection where polarity is fixed and reverse conduction is not required.
Does the SMA5J5.0-E3/5A meet automotive reliability standards?
Yes, the SMA5J5.0-E3/5A is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While the base E3 suffix is not AEC-Q101 qualified, the identical SMA5J5.0AHE3/5A variant carries full AEC-Q101 certification. The SMA5J5.0-E3/5A shares all electrical and thermal specs with the HE3 version and is widely used in non-safety automotive applications such as infotainment and body control modules.
What is the maximum clamping voltage of the SMA5J5.0-E3/5A during a surge event?
The SMA5J5.0-E3/5A has a maximum clamping voltage (VC) of 54.3 V at its rated peak pulse current (IPPM) of 9.2 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the highest voltage imposed on the protected circuit during worst-case transient conditions and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
Can the SMA5J5.0-E3/5A be used in bidirectional applications?
No-the SMA5J5.0-E3/5A is strictly unidirectional. For bidirectional protection, Vishay specifies the SMA5J5.0CA variant (with "CA" suffix), which lacks polarity marking and provides symmetrical clamping in both directions. Using the SMA5J5.0-E3/5A in AC or floating signal paths risks failure due to unintended forward conduction during negative half-cycles.
What PCB pad layout is recommended for optimal thermal performance of the SMA5J5.0-E3/5A?
Vishay specifies mounting the SMA5J5.0-E3/5A on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 500 W pulse power. Smaller pads reduce heat dissipation, derating peak power significantly-e.g., at 75 °C ambient, power must be reduced per Figure 2 in the datasheet. Thermal vias under pads further improve junction-to-board conduction for sustained surge duty cycles.
