Product details
Overview
SMA5J6.0HE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) 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), 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive power rail protection.
For engineers reviewing the SMA5J6.0HE3/61 datasheet, SMA5J6.0HE3/61 pinout, SMA5J6.0HE3/61 application, or SMA5J6.0HE3/61 equivalent, key selection criteria include unidirectional polarity, 10.3 V clamping voltage at 48.5 A, DO-214AC thermal resistance (RθJA = 80 °C/W), RoHS-compliant AEC-Q101 qualification, and 150 °C max junction temperature.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protector with avalanche breakdown behavior. Its glass-passivated junction ensures stable leakage (<800 µA at 6.0 V) and fast response (<1 ns), while the low incremental surge resistance enables effective energy diversion during transients like ISO 7637-2 pulses.
The device is rated for non-repetitive 10/1000 µs surges up to 500 W when mounted on 5.0 mm × 5.0 mm copper pads. Thermal performance is defined by RθJA = 80 °C/W and RθJL = 25 °C/W, supporting reliable operation in automotive under-hood environments up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Ensures reliable turn-on above normal operating voltage with margin |
| VC @ IPPM | ≤10.3 V at 48.5 A - Clamping voltage limits downstream IC stress during 500 W surge events |
| PPPM | 500 W (10/1000 µs) - Sustains high-energy transients common in automotive load-dump and inductive switching |
| IFSM | 40 A (8.3 ms half-sine) - Withstands single-event forward surge without degradation |
| TJ max | +150 °C - Enables use in engine control units and other high-temperature automotive locations |
| Leakage ID | ≤800 µA at VWM - Minimizes standby power loss in always-on circuits |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 6.0 V.

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-E3/61 | Same electrical specs (VWM, VBR, PPPM, VC), but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; not suitable for under-hood or safety-critical systems | Select SMA5J6.0HE3/61 for automotive designs requiring AEC-Q101; use SMA5J6.0A-E3/61 for cost-sensitive consumer applications. |
| SMBJ6.0AHE3/52 | Same VWM/VC, but SMB package (DO-214AA); 600 W PPPM, higher IPPM (53.3 A), RθJA = 65 °C/W | Higher power handling and better thermal dissipation, but larger footprint (4.58 mm × 3.94 mm vs. 4.50 mm × 2.79 mm) | Choose SMBJ6.0AHE3/52 when board space allows and >500 W surge margin is required; retain SMA5J6.0HE3/61 for compact automotive modules. |
Compared with SMA5J6.0A-E3/61, the SMA5J6.0HE3/61 adds AEC-Q101 qualification for automotive use; compared with SMBJ6.0AHE3/52, it trades 100 W peak power and thermal margin for 30 % smaller PCB area-critical in dense ECU layouts.

FAQ
What is the clamping voltage of the SMA5J6.0HE3/61 under full-rated surge current?
The SMA5J6.0HE3/61 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured at the device terminals under standardized test conditions with 5.0 mm × 5.0 mm copper pads per lead. The clamping voltage directly determines the maximum stress imposed on downstream circuitry during surge events, making it a critical parameter for system-level overvoltage design margins.
Is the SMA5J6.0HE3/61 suitable for bi-directional transient protection?
No, the SMA5J6.0HE3/61 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). It conducts only in reverse bias and must be oriented with the cathode band toward the protected line's higher potential. For bi-directional protection-such as AC signal lines or differential buses-devices like SMA5J6.0CA would be required. Using SMA5J6.0HE3/61 in bi-directional configurations risks forward conduction and failure during positive transients.
What does the "HE3" suffix signify in SMA5J6.0HE3/61?
The "HE3" suffix in SMA5J6.0HE3/61 denotes two key attributes: "H" indicates AEC-Q101 qualification for automotive applications, and "E3" confirms RoHS compliance and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial-grade "E3" variant (e.g., SMA5J6.0A-E3/61), which lacks automotive qualification. The "61" refers to the 7-inch tape-and-reel packaging format containing 1800 units.
How does the thermal performance of SMA5J6.0HE3/61 affect PCB layout?
The SMA5J6.0HE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per lead. To maintain TJ ≤150 °C during repeated surges, PCB layout must provide adequate copper area and minimize trace length to ground. Reducing pad size or using thinner copper increases thermal resistance, potentially causing premature thermal runaway during high-duty-cycle transients-especially in automotive under-hood environments.
Can SMA5J6.0HE3/61 replace SMAJ6.0A in existing designs?
The SMA5J6.0HE3/61 is not a direct replacement for SMAJ6.0A due to differences in surge rating: SMAJ6.0A is rated for 400 W (10/1000 µs), while SMA5J6.0HE3/61 delivers 500 W. Though both use DO-214AC packages and share identical pinout and VWM/VC specs, the higher power rating of SMA5J6.0HE3/61 may alter thermal decay profiles and system-level surge margin calculations. Requalification per IEC 61000-4-5 or ISO 7637-2 is recommended before substitution.
