Product details
Overview
SMA6J5.0A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping ESD and surge transients on 5.0 V signal/power lines. It delivers 600 W peak pulse power (10/1000 μs), 9.1 V maximum clamping voltage at 65.9 A IPP, and 6.4–7.07 V breakdown voltage at 10 mA, with 150 μA reverse leakage at 5.0 V stand-off voltage. Used to protect MOSFET gates, sensor I/O, and USB/UART lines in industrial control systems.
For engineers reviewing the SMA6J5.0A-E3/61 datasheet, SMA6J5.0A-E3/61 pinout, SMA6J5.0A-E3/61 application, or SMA6J5.0A-E3/61 equivalent, key selection criteria include clamping voltage vs. surge current, unidirectional polarity constraint, SMA package thermal resistance (RθJA = 120 °C/W), and compatibility with automated SMT placement per J-STD-020 MSL level 1.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias (≤5.0 V), it presents high impedance (<150 μA leakage); during transients exceeding VBR (6.4–7.07 V), it avalanches rapidly to clamp voltage to ≤9.1 V at 65.9 A. Its dynamic resistance is 0.031 Ω, enabling low-voltage overshoot suppression.
Designed for PCB-level protection of low-voltage IC interfaces, it requires no external biasing or control logic. Thermal performance is defined by junction-to-ambient resistance (120 °C/W) and max operating temperature (150 °C), with derating above TA = 25 °C per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse voltage before leakage exceeds 150 μA; sets upper limit for protected line DC operation. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Breakdown onset range; ensures reliable triggering above nominal 5.0 V rail without false conduction. |
| VC @ IPP | 9.1 V at 65.9 A (10/1000 μs) - Clamped voltage seen by downstream circuitry during worst-case surge; defines protection margin. |
| PPPM | 600 W (10/1000 μs) - Peak transient energy handling capacity; determines survivability against lightning-induced surges. |
| ID @ VWM | 150 μA - Reverse leakage at rated stand-off; low enough to avoid loading 5 V logic or sensor reference rails. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; dictates required copper pad area (5.0 mm × 5.0 mm per terminal) for thermal management. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional, cathode indicated by color band. Matte tin-plated leads, RoHS-compliant (E3), MSL level 1, 260 °C reflow compatible.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/61 | 400 W PPPM (10/1000 μs), higher clamping voltage (9.2 V @ 43.4 A), same SMA package and VWM. | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance where 600 W rating is mandatory. | Select SMA6J5.0A-E3/61 when surge immunity requirements exceed 400 W, especially in industrial PLC backplanes. |
| SMCJ5.0A-E3/73 | 1500 W PPPM (10/1000 μs), larger SMC (DO-214AB) package, same VWM and polarity. | Requires larger PCB footprint and higher thermal mass; better suited for primary AC/DC input stage protection than board-level signal lines. | Choose SMA6J5.0A-E3/61 for space-constrained 5 V signal path protection where SMC footprint is prohibitive. |

FAQ
What is the maximum clamping voltage of the SMA6J5.0A-E3/61 at its rated peak pulse current?
The SMA6J5.0A-E3/61 has a maximum clamping voltage (VC) of 9.1 V at 65.9 A peak pulse current (IPP) under a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 89460) and defines the upper voltage limit imposed on protected circuits during surge events. The SMA6J5.0A-E3/61 maintains this clamping performance across its specified operating temperature range.
Is the SMA6J5.0A-E3/61 suitable for bidirectional signal line protection?
No, the SMA6J5.0A-E3/61 is unidirectional only, as confirmed in the Vishay datasheet features section and electrical characteristics table. It must be oriented with cathode toward ground to function correctly. For bidirectional protection (e.g., RS-485 or Ethernet), a different device such as the SMBJ5.0CA-E3/52 is required. The SMA6J5.0A-E3/61 polarity is marked by a cathode band on the SMA package body.
What is the thermal resistance and recommended PCB layout for the SMA6J5.0A-E3/61?
The SMA6J5.0A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, measured with 5.0 mm × 5.0 mm copper pads per terminal per datasheet note (2). This layout is mandatory to achieve rated power dissipation and prevent thermal runaway during repetitive surges. The SMA6J5.0A-E3/61 must not be used on minimal copper land patterns without derating.
Does the SMA6J5.0A-E3/61 meet RoHS and lead-free assembly requirements?
Yes, the SMA6J5.0A-E3/61 is RoHS-compliant and qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL level 1. The "E3" suffix explicitly denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads that comply with J-STD-002 and JESD 22-B102 solderability standards. The SMA6J5.0A-E3/61 is also whisker-tested per JESD 201 class 2.
How does the breakdown voltage tolerance of the SMA6J5.0A-E3/61 affect circuit design?
The SMA6J5.0A-E3/61 has a specified VBR range of 6.4 V to 7.07 V at 10 mA, meaning actual units may trigger anywhere within that window. Designers must ensure the protected circuit's absolute maximum input voltage exceeds 7.07 V to avoid false triggering, while maintaining sufficient margin below the clamping voltage (9.1 V). This tolerance is inherent to avalanche diode physics and is documented in the Vishay SMA6J5.0A-E3/61 datasheet Table 1.
