Product details
Overview
SMA5J6.5CHE3/61 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 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 44.6 A peak pulse current (IPPM), and clamps to 11.2 V at rated surge. It is AEC-Q101 qualified and used in automotive power rail protection.
For engineers reviewing the SMA5J6.5CHE3/61 datasheet, SMA5J6.5CHE3/61 pinout, SMA5J6.5CHE3/61 application, or SMA5J6.5CHE3/61 equivalent, key selection criteria include unidirectional polarity, 11.2 V clamping voltage at 44.6 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 protection device in series with DC power rails or parallel to sensitive inputs. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients induced by inductive switching or load dump.
Designed for surface-mount automated assembly, it uses a DO-214AC case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, supporting automotive-grade reliability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5AHE3/61 | Same electrical specs; identical HE3 suffix (AEC-Q101, Class 2 whisker); differs only in packaging code notation | No functional difference; both intended for automotive use | Select SMA5J6.5CHE3/61 when ordering from distributors using /61 reel code with "CH" variant marking convention |
| SMC5J6.5AHE3/61 | Same VWM/VBR/VC but in larger DO-214AB (SMC) package; RθJA = 35 °C/W vs. 80 °C/W; 1500 W PPPM | Better thermal performance and higher surge rating; requires larger PCB area | Choose SMC5J6.5AHE3/61 where board space permits and >500 W surge margin is required |
Compared with SMA5J6.5AHE3/61 (identical spec), SMA5J6.5CHE3/61 offers identical protection performance in the same DO-214AC footprint; versus SMC5J6.5AHE3/61, it trades lower surge capacity and higher thermal resistance for compact size-ideal for space-constrained automotive modules.

FAQ
What is the clamping voltage of the SMA5J6.5CHE3/61 under full-rated surge conditions?
The SMA5J6.5CHE3/61 clamps to 11.2 V at its rated peak pulse current of 44.6 A under a 10/1000 µs waveform. This value is measured per standard test conditions in the Vishay datasheet and defines the maximum voltage imposed on protected circuitry during a worst-case transient event. The clamping behavior is repeatable due to the device's glass-passivated junction and low incremental resistance.
Is SMA5J6.5CHE3/61 suitable for automotive applications?
Yes, SMA5J6.5CHE3/61 is AEC-Q101 qualified and carries the HE3 suffix, confirming compliance with automotive stress testing including temperature cycling, humidity bias, and mechanical shock. Its 150 °C maximum junction temperature, MSL Level 1 rating, and JESD 201 Class 2 whisker resistance make it appropriate for engine control units, body electronics, and ADAS power domains.
What does the "HE3" suffix mean in SMA5J6.5CHE3/61?
The "HE3" suffix in SMA5J6.5CHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial "E3" variants and confirms suitability for automotive production. The "CH" segment reflects Vishay's internal variant coding for tape-and-reel packaging with specific reel diameter and quantity configuration.
How does SMA5J6.5CHE3/61 differ from SMA5J6.5A-E3/61?
SMA5J6.5CHE3/61 and SMA5J6.5A-E3/61 share identical electrical parameters and DO-214AC packaging, but differ in qualification level: SMA5J6.5CHE3/61 is AEC-Q101 qualified (HE3), while SMA5J6.5A-E3/61 is commercial-grade (E3). The "CH" vs. "A" marking reflects Vishay's internal product segmentation for automotive vs. general-purpose use cases.
What is the thermal resistance of SMA5J6.5CHE3/61, and how does it affect layout design?
SMA5J6.5CHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides PCB copper pour sizing: reducing thermal resistance requires increasing pad area or adding thermal vias. For sustained surge duty, designers should verify junction temperature stays below 150 °C using actual ambient and power dissipation data.
