Product details
Overview
SA36CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 8.6 A peak pulse current (IPPM), and 58.1 V maximum clamping voltage (VC) - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SA36CHE3/54 datasheet, SA36CHE3/54 pinout, SA36CHE3/54 application, or SA36CHE3/54 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-15 mechanical data, clamping performance under 10/1000 μs surge, and direct alternatives for automotive and industrial transient protection design.
Technical Context
The SA36CHE3/54 operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<1.0 μA at VWM), while the 175 °C max junction temperature supports operation in under-hood automotive environments.
It complies with AEC-Q101 stress testing for automotive-grade reliability and uses matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The device exhibits low incremental surge resistance and fast response time (<1 ns), critical for suppressing sub-microsecond ESD events per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 24 V nominal systems. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - guaranteed avalanche onset range; ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 58.1 V at 8.6 A (10/1000 μs) - clamped voltage seen by protected circuit; limits downstream stress to <60 V during 500 W surge. |
| PPPM | 500 W - peak pulse power handling capability; sustains standardized lightning/surge waveforms without failure. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage at rated stand-off; avoids signal distortion or bias shift in high-impedance sensor lines. |
| TJ max | +175 °C - extended thermal rating enables use in engine control units and motor drive PCBs near heat sources. |
| Qualification | AEC-Q101 qualified - validated for automotive applications including powertrain and body electronics per stress test requirements. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | Same VWM (36 V), same DO-214AC package; lower PPPM (400 W), higher VC (60.0 V), non-AEC-Q101. | Limited to commercial-grade industrial and consumer applications; not qualified for automotive under-hood deployment. | Select SMAJ36CA only when AEC-Q101 is not required and board space allows larger SMA footprint. |
| 1.5KE36CA | Same VWM (36 V), higher PPPM (1500 W), axial DO-201AD package; larger size, higher clamping (63.0 V), AEC-Q101 not claimed. | Better suited for high-energy surge zones (e.g., AC mains entry); incompatible with DO-15 footprint and automated assembly reels. | Choose 1.5KE36CA where energy absorption >500 W is mandatory and manual placement or through-hole assembly is acceptable. |
Compared with SMAJ36CA and 1.5KE36CA, SA36CHE3/54 uniquely combines AEC-Q101 qualification, DO-15 form factor, 500 W surge rating, and 58.1 V clamping in a RoHS-compliant, reel-ready (54 tape code) configuration - making it optimal for automotive Tier-1 production and space-constrained industrial PCBs requiring zero-layout redesign.

FAQ
What is the clamping voltage of SA36CHE3/54 at its rated peak pulse current?
The SA36CHE3/54 has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 8.6 A under the standard 10/1000 μs waveform. This value is measured per the test conditions defined in Vishay document 88378 and reflects the upper limit of voltage imposed on protected circuitry during a full-power transient event. The SA36CHE3/54 maintains this clamping performance consistently across its qualified temperature range.
Is SA36CHE3/54 suitable for automotive applications?
Yes, SA36CHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction, and validation across temperature cycling, HTRB, and ESD stress tests confirm suitability for engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade E3 variants.
What does the "HE3/54" suffix mean in SA36CHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" specifies the preferred packaging code - 13-inch paper tape and reel with 4000 units per reel. This format enables automated SMT placement and supports high-volume automotive production traceability requirements. The SA36CHE3/54 part number fully identifies both reliability grade and logistics configuration.
How does SA36CHE3/54 differ from uni-directional SA36A variants?
SA36CHE3/54 is bi-directional with symmetrical breakdown and clamping in both polarities, while SA36A is uni-directional and features a cathode band. The SA36CHE3/54 has no polarity marking and can protect AC signals or differential pairs without orientation concerns; SA36A requires correct anode/cathode placement and is limited to DC-biased lines. Their VBR and VC values also differ slightly due to structural asymmetry in uni-directional devices.
What is the maximum reverse leakage current for SA36CHE3/54 at its stand-off voltage?
The SA36CHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 36 V and TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power loss in battery-powered systems. Leakage remains well below 10 μA even at elevated temperatures up to 125 °C, as confirmed by Vishay's derating curves.
