Product details
Overview
SMA5J6.0A-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 10.3 V clamping voltage (VC) at 48.5 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J6.0A-E3/5A datasheet, SMA5J6.0A-E3/5A pinout, SMA5J6.0A-E3/5A application, or SMA5J6.0A-E3/5A equivalent, key selection criteria include unidirectional polarity, RoHS-compliant matte tin-plated leads, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification availability via HE3 suffix variants - critical for automotive-grade ESD/surge resilience in harsh environments.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 6.0 V and rapidly transitions to low-impedance conduction above VBR ≥ 6.67 V to limit transient energy. Its glass-passivated junction ensures stable leakage (<800 μA at VWM) and fast response time (<1 ns), enabling protection against ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges (IEC 61000-4-5).
Thermal performance is defined by RθJA = 80 °C/W and RθJL = 25 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device is rated for non-repetitive 40 A forward surge (8.3 ms half-sine) and meets J-STD-020 reflow profile (260 °C peak), making it suitable for automated SMT assembly on standard PCB pad layouts.
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 |
|---|---|---|---|
| SMAJ6.0A-E3/5A | Lower PPPM (400 W vs. 500 W); identical VWM, VBR, and package; higher VC (10.5 V at 38.9 A). | Less robust for high-energy transients (e.g., ISO 7637-2 Pulse 5a); suitable only where surge energy is limited to ≤400 W. | Select SMA5J6.0A-E3/5A when full 500 W IEC 61000-4-5 Level 4 compliance is required; choose SMAJ6.0A-E3/5A only for cost-sensitive, lower-energy applications. |

FAQ
What is the polarity configuration of the SMA5J6.0A-E3/5A?
The SMA5J6.0A-E3/5A is a unidirectional transient voltage suppressor diode, with the cathode identified by a visible band on the SMA (DO-214AC) package body. This polarity enables clamping only during positive transients relative to ground, making it suitable for protecting DC power rails and single-ended signal lines where reverse conduction is not required.
Does the SMA5J6.0A-E3/5A meet automotive qualification standards?
The base SMA5J6.0A-E3/5A is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified variant is available as SMA5J6.0AHE3_A/I (halogen-free, RoHS-compliant, and AEC-Q101 qualified). This qualified version undergoes stress testing per AEC-Q101 Rev D and is approved for use in automotive powertrain, body, and ADAS systems.
What is the maximum clamping voltage of the SMA5J6.0A-E3/5A under surge conditions?
The SMA5J6.0A-E3/5A has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 48.5 A, measured using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 500 W transient event.
Can the SMA5J6.0A-E3/5A be used in bidirectional protection applications?
No - the SMA5J6.0A-E3/5A is strictly unidirectional. For bidirectional transient suppression, Vishay specifies the CA-suffixed variant (e.g., SMA5J6.0CA), which exhibits symmetrical clamping in both polarities and uses no polarity marking. Using SMA5J6.0A-E3/5A in bidirectional configurations risks catastrophic failure during negative transients.
What is the moisture sensitivity level (MSL) rating for the SMA5J6.0A-E3/5A?
The SMA5J6.0A-E3/5A is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard reflow soldering profiles without preconditioning or baking. Its peak reflow temperature tolerance is 260 °C, fully compatible with lead-free assembly processes.
