Product details
Overview
SMA5J6.0AHE3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power 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. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the SMA5J6.0AHE3/5A datasheet, SMA5J6.0AHE3/5A pinout, SMA5J6.0AHE3/5A application, or SMA5J6.0AHE3/5A equivalent, key selection criteria include clamping performance under 48.5 A surge, unidirectional polarity marking (cathode band), RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging an avalanche junction to clamp reverse surges above VWM while maintaining low leakage (<800 µA at 6.0 V). Its glass-passivated chip junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device is rated for 150 °C maximum junction temperature and exhibits 25 °C/W junction-to-lead thermal resistance, enabling effective heat dissipation when mounted per recommended pad layout. It meets MSL Level 1 per J-STD-020 and supports peak forward surge current of 40 A (8.3 ms half-sine) in unidirectional configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system overvoltage threshold. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures consistent turn-on across production lots. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamped voltage during 500 W transient; defines worst-case stress on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling with 10/1000 µs waveform; validates protection against IEC 61000-4-5 Level 4 surges. |
| IFSM | 40 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush and load-dump immunity in automotive power rails. |
| TJ max. | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| Package | SMA (DO-214AC) - Surface-mount package with 5.28 mm × 4.50 mm footprint; compatible with standard SMT reflow profiles. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated. Polarity indicated by cathode band at one end.

| Low incremental surge resistance | Enables tighter VC–IPPM correlation and predictable clamping margin across production batches. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking; simplifies SMT manufacturing flow. |
| Automated placement compatibility | Standardized SMA outline and lead coplanarity support high-yield pick-and-place at >30,000 UPH. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges up to 500 W. Use Value: Limits peak rail voltage to ≤10.3 V during 48.5 A transients, preventing damage to 16 V-rated microcontrollers and CAN transceivers. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS on 0–5 V or 4–20 mA signal lines, positioned adjacent to connector entry point. Use Value: Sub-11 V clamping preserves ADC input integrity and avoids false triggering in 12-bit measurement systems. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feed Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters subjected to lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Standoff-rated TVS on +5 V or +12 V output rail, upstream of LDO regulators. Use Value: Absorbs 500 W pulses without degradation, maintaining regulated output within ±5 % during transient recovery. |
Use Scenario: DC feed protection in PoE-powered base stations where 48 V supply lines are exposed to induced surges. IC Role / Device Role / Timing Role: Unidirectional clamping device on PSE-side feed line, referenced to local ground plane. Use Value: Withstands repeated 48 V × 48.5 A surges while holding clamp voltage below 10.3 V, safeguarding Ethernet PHYs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0A-E3/5A | No AEC-Q101 qualification; commercial grade only; identical electrical specs and package. | Suitable for non-automotive industrial or consumer use where automotive reliability testing is not required. | Select when cost sensitivity outweighs automotive qualification needs and ambient temperature stays ≤125 °C. |
| SMA5J6.0CAHE3/5A | Bidirectional variant; symmetric VBR (±6.67–7.37 V); same VC, PPPM, and package. | Required for AC-coupled or floating signal lines (e.g., RS-485, audio) where polarity reversal may occur. | Choose only if bidirectional clamping is mandatory; otherwise unidirectional SMA5J6.0AHE3/5A offers lower leakage and simpler grounding. |
Compared with SMA5J6.0A-E3/5A, the HE3 suffix adds AEC-Q101 qualification and extended temperature validation; compared with SMA5J6.0CAHE3/5A, the unidirectional version provides lower reverse leakage and eliminates need for symmetrical layout, reducing PCB area and grounding complexity.

FAQ
What is the clamping voltage of the SMA5J6.0AHE3/5A under maximum rated surge current?
The SMA5J6.0AHE3/5A clamps to 10.3 V when subjected to its peak pulse current of 48.5 A using a 10/1000 µs waveform. This value is measured and guaranteed per Vishay's datasheet (Document Number: 88875, Rev. 09-Jan-2024) and defines the maximum voltage seen by downstream circuitry during transient events. The SMA5J6.0AHE3/5A maintains this clamping performance across its full operating temperature range.
Is the SMA5J6.0AHE3/5A suitable for automotive applications?
Yes, the SMA5J6.0AHE3/5A is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in Vishay's official datasheet. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and surge endurance, making it suitable for under-hood and body-control module applications. The SMA5J6.0AHE3/5A is explicitly designated for automotive use per Vishay's ordering nomenclature guide.
What does the "/5A" suffix indicate in SMA5J6.0AHE3/5A?
The "/5A" suffix denotes the packaging configuration: 7500 units per 13-inch diameter plastic tape and reel. This format supports high-volume automated assembly and is distinct from "/61", which indicates 1800 units per 7-inch reel. The SMA5J6.0AHE3/5A shares identical electrical and thermal specifications regardless of reel size.
How does the SMA5J6.0AHE3/5A differ from the SMA5J6.0A-E3/5A?
The SMA5J6.0AHE3/5A includes AEC-Q101 qualification and extended reliability validation, while the SMA5J6.0A-E3/5A is commercial-grade only. Both share identical VWM, VBR, VC, PPPM, and package. The SMA5J6.0AHE3/5A is intended for automotive and mission-critical industrial use; the E3 version suits cost-sensitive consumer or non-automotive applications.
What is the maximum junction temperature rating for the SMA5J6.0AHE3/5A?
The SMA5J6.0AHE3/5A has a maximum junction temperature (TJ) rating of +150 °C, as specified in the Thermal Characteristics table of Vishay's datasheet. This allows reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. Derating curves in Figure 2 confirm usable power capability down to 50 % of PPPM at 125 °C ambient.
