Product details
Overview
SMA5J6.0-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 10.3 V clamping voltage at 48.5 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMA5J6.0-E3/5A datasheet, SMA5J6.0-E3/5A pinout, SMA5J6.0-E3/5A application, or SMA5J6.0-E3/5A equivalent, key selection criteria include clamping performance under 48.5 A surge, thermal resistance (RθJA = 80 °C/W), AEC-Q101 qualification status, RoHS compliance (E3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device-cathode-banded end connects to protected line, anode to ground-triggering when reverse voltage exceeds VBR (6.67–7.37 V). Its glass-passivated junction ensures stable leakage (<800 µA at 6.0 V) and fast response time (<1.0 ps), critical for protecting MOSFET gates and IC inputs against ESD and inductive switching transients.
Rated for -55 °C to +150 °C junction temperature, it delivers 500 W peak pulse power under standardized 10/1000 µs waveform with derating above 25 °C ambient. The DO-214AC package supports MSL Level 1 handling and meets JESD201 Class 1A whisker resistance, enabling reliable reflow soldering in automotive and industrial assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe DC bias margin for protected circuit. |
| VBR (min/max) | 6.67 V / 7.37 V - Measured at 10 mA test current; defines guaranteed conduction onset window for design margining. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| PPPM | 500 W - Peak pulse power handling per single transient; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <800 µA - Reverse leakage at rated stand-off voltage; ensures minimal quiescent power loss in battery-powered systems. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, low-profile plastic case with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Protected line connection | Reverse-biased terminal that conducts during overvoltage events; must be placed upstream of load to clamp transients. |
| Anode | Ground reference | Low-impedance return path to system ground; requires minimum 5.0 mm × 5.0 mm copper pad for thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage drift across temperature and lifetime, critical for long-term reliability in automotive ECUs. |
| AEC-Q101 qualified (HE3 variant); E3 suffix is commercial grade | SMA5J6.0-E3/5A is RoHS-compliant commercial-grade; HE3 variants are automotive-qualified-designers must select HE3 for AEC-Q101-requiring applications. |
| Low incremental surge resistance | Enables tighter clamping (VC = 10.3 V) at high IPPM (48.5 A), reducing voltage overshoot beyond protected IC absolute maximum ratings. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free reflow profiles without moisture-related popcorn failure, eliminating bake requirements pre-assembly. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0AHE3/5A | AEC-Q101 qualified; identical electrical specs but validated for automotive temperature cycling and humidity testing. | Required for under-hood, ADAS, or infotainment modules needing automotive qualification. | Select SMA5J6.0AHE3/5A when AEC-Q101 compliance is mandated; SMA5J6.0-E3/5A is suitable for commercial/industrial use only. |
| P6SMB6.0A | Same DO-214AA package, 6.0 V VWM, but lower PPPM (600 W) and higher VC (10.5 V at 48.2 A); not AEC-Q101 qualified. | Better suited for cost-sensitive consumer electronics where 600 W margin suffices and automotive qualification is unnecessary. | Choose P6SMB6.0A for non-automotive designs requiring slightly higher surge margin but no AEC-Q101 validation. |
Compared with SMA5J6.0-E3/5A, SMA5J6.0AHE3/5A adds automotive qualification without changing electrical behavior, while P6SMB6.0A trades AEC-Q101 for higher peak power but looser clamping-making each optimal for distinct reliability and performance tiers.

FAQ
What is the clamping voltage of the SMA5J6.0-E3/5A under maximum surge conditions?
The SMA5J6.0-E3/5A clamps to 10.3 V at its rated peak pulse current of 48.5 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the maximum voltage seen by downstream circuitry during a full-power transient event. The SMA5J6.0-E3/5A maintains this clamping performance across its specified junction temperature range of -55 °C to +150 °C, with minor derating above 25 °C ambient.
Is the SMA5J6.0-E3/5A suitable for automotive applications?
The SMA5J6.0-E3/5A is RoHS-compliant and built in an AEC-Q101-qualified platform, but the E3 suffix denotes commercial-grade qualification-not automotive. For automotive use, the SMA5J6.0AHE3/5A variant must be selected, as it undergoes full AEC-Q101 stress testing. The SMA5J6.0-E3/5A remains appropriate for industrial and consumer applications where AEC-Q101 is not required.
What is the meaning of the "-E3/5A" suffix in SMA5J6.0-E3/5A?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "5A" specifies the packaging format: 7500 units per 13-inch diameter plastic tape and reel. This differs from "/61", which denotes 1800 units per 7-inch reel. The SMA5J6.0-E3/5A uses matte tin-plated leads and meets J-STD-002 solderability standards.
How does the SMA5J6.0-E3/5A compare to the SMA5J6.0A part number?
SMA5J6.0-E3/5A and SMA5J6.0A share identical electrical specifications-including VWM = 6.0 V, VBR = 6.67–7.37 V, and VC = 10.3 V-but differ in packaging and compliance. SMA5J6.0A is a base part number; SMA5J6.0-E3/5A adds RoHS compliance (E3), commercial qualification, and 13″ tape-and-reel packaging (5A). No functional difference exists between them beyond these logistics and compliance attributes.
What PCB layout guidance applies to the SMA5J6.0-E3/5A for optimal thermal performance?
For optimal thermal dissipation, the SMA5J6.0-E3/5A must be mounted on minimum 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. These pads should connect to internal ground/power planes via multiple thermal vias. The SMA5J6.0-E3/5A's RθJA = 80 °C/W is validated under this layout; reducing pad size increases junction temperature and degrades surge endurance.
