Product details
Overview
SMA6J5.0A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 9.1 V maximum clamping voltage (VC) at 65.9 A peak pulse current (IPP), and 600 W peak pulse power (10 × 1000 μs). It protects MOSFETs and ICs in industrial power supplies against inductive switching surges.
For engineers reviewing the SMA6J5.0A-E3/5A datasheet, SMA6J5.0A-E3/5A pinout, SMA6J5.0A-E3/5A application, or SMA6J5.0A-E3/5A equivalent, key selection criteria include unidirectional polarity, 9.1 V clamping at 65.9 A, 120 °C/W junction-to-ambient thermal resistance, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered above its breakdown threshold, using avalanche breakdown to divert surge energy away from protected circuitry. Its dynamic resistance of 0.031 Ω enables low-voltage overshoot during 10/1000 μs transients, while its 150 °C maximum junction temperature supports operation in thermally constrained industrial environments.
The SMA6J5.0A-E3/5A is rated for 4 W power dissipation at TA = 50 °C and withstands 50 A non-repetitive forward surge current (8.3 ms half-sine), making it suitable for protecting DC input rails and sensor interfaces subject to load dump or ESD events. Its MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility ensure robust manufacturability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Stand-off voltage; ensures no conduction during normal 5 V rail operation |
| VBR min/max | 6.4 V / 7.07 V at IT = 10 mA - Defines precise avalanche initiation range for predictable clamping onset |
| VC at IPP | 9.1 V at 65.9 A (10 × 1000 μs) - Maximum clamped voltage seen by protected IC under standard surge test |
| PPPM | 600 W (10 × 1000 μs) - Surge energy handling capacity for long-duration transients like inductive kickback |
| ID at VWM | 150 μA max - Low leakage preserves efficiency in battery-powered or high-impedance sensor circuits |
| RθJA | 120 °C/W - Thermal resistance determines required PCB copper area for thermal management at 4 W dissipation |
| Polarity | Unidirectional - Protects only against positive-going transients; requires correct cathode orientation |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating. Cathode indicated by color band. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/5A | Lower PPPM (400 W vs. 600 W), higher VC (11.2 V at 32.4 A), same SMA package and VWM | Less robust for high-energy inductive transients; suitable only where surge amplitude is lower and layout allows tighter clamping margin | Select SMA6J5.0A-E3/5A when 600 W surge immunity and 9.1 V clamping are required for critical 5 V rail protection. |
| 1.5SMC5.0A | Higher package thermal mass (SMC/DO-214AB), 600 W PPPM, but larger footprint and 10.5 V VC at 57.1 A | Requires more PCB area; better for high-reliability industrial designs needing enhanced thermal derating margin | Choose SMA6J5.0A-E3/5A for space-constrained SMT designs where 1.2 mm height and 5.28 mm length are critical. |
Compared with SMAJ5.0A-E3/5A and 1.5SMC5.0A, the SMA6J5.0A-E3/5A delivers superior clamping performance (9.1 V vs. 11.2 V/10.5 V) in the smallest SMA footprint, making it optimal for high-density 5 V rail protection where both surge energy and board space are limiting factors.

FAQ
What is the maximum clamping voltage of the SMA6J5.0A-E3/5A under standard surge conditions?
The SMA6J5.0A-E3/5A has a maximum clamping voltage (VC) of 9.1 V when subjected to a 10 × 1000 μs waveform at 65.9 A peak pulse current (IPP). This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during a typical inductive switching transient. The SMA6J5.0A-E3/5A maintains this clamping performance across its specified operating temperature range.
Is the SMA6J5.0A-E3/5A suitable for automotive applications?
Yes, the SMA6J5.0A-E3/5A is qualified for industrial-grade operation from -55 °C to +150 °C and meets MSL Level 1 for lead-free reflow, making it suitable for under-hood and body-control module applications. While not AEC-Q200 certified out-of-box, its electrical parameters-including 50 A IFSM and 4000 W (8 × 20 μs) surge capability-align with common automotive transient immunity requirements. System-level validation is recommended for safety-critical use. The SMA6J5.0A-E3/5A is widely deployed in non-safety automotive subsystems.
What does the "E3/5A" suffix indicate in SMA6J5.0A-E3/5A?
The "E3" denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, while "5A" specifies the packaging configuration: 7500 units per 13-inch diameter plastic tape and reel. This differs from "E3/61", which uses 7-inch reels with 1800 units. The SMA6J5.0A-E3/5A is optimized for high-volume SMT assembly lines requiring large reel quantities and full RoHS compliance.
How does the thermal resistance of the SMA6J5.0A-E3/5A affect PCB layout?
The SMA6J5.0A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W. To maintain safe operation at its 4 W power dissipation limit (at TA = 50 °C), the PCB must provide adequate copper area-specifically, 5.0 mm × 5.0 mm pads per terminal as specified in the datasheet. Reducing pad size increases junction temperature and risks premature failure during repeated surges. The SMA6J5.0A-E3/5A thermal performance is validated only with this minimum layout.
Can the SMA6J5.0A-E3/5A be used in bidirectional protection circuits?
No, the SMA6J5.0A-E3/5A is unidirectional only, with polarity marked by a cathode band. It clamps only positive transients relative to ground. For bidirectional protection (e.g., AC lines or data buses with ± surges), a separate bidirectional TVS such as SMA6J5.0CA or dual-diode configurations are required. Using two SMA6J5.0A-E3/5A devices back-to-back is not recommended due to mismatched VBR and undefined behavior under reverse conduction. The SMA6J5.0A-E3/5A datasheet explicitly states unidirectional polarity only.
