Product details
Overview
SA36CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR at 1 mA), 58.1 V maximum clamping voltage (VC) at 8.6 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SA36CAHE3/54 datasheet, SA36CAHE3/54 pinout, SA36CAHE3/54 application, or SA36CAHE3/54 equivalent, this AEC-Q101 qualified TVS provides validated bidirectional clamping performance, DO-15 mechanical compatibility, and traceable RoHS-compliant sourcing for production-grade ESD and surge protection design.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) transient voltage exceeds VBR, it avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability automotive and industrial environments. The HE3 suffix confirms AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected line. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - precise avalanche onset threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 58.1 V at 8.6 A - clamped voltage under 10/1000 µs surge; limits stress on downstream ICs like microcontrollers or transceivers. |
| PPPM | 500 W - peak pulse power handling capability; sustains short-duration transients without failure. |
| ID @ VWM | <1.0 µA - ultra-low reverse leakage at rated standoff; avoids signal distortion or power loss in high-impedance circuits. |
| TJ max. | +175 °C - extended thermal operating limit; enables placement near heat sources or in under-hood automotive locations. |
| AEC-Q101 | Qualified - validated reliability for automotive electronics per stress test requirements including HTOL, TC, UHAST. |
Pinout & Package
Package: DO-15 (DO-204AC), axial lead, molded epoxy case with UL 94 V-0 flammability rating. Matte tin-plated leads; no polarity marking (bidirectional device).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No cathode band; terminals interchangeable - enables single-component protection of AC-coupled or differential signal lines. |
| Lead 1 | Terminal connection | Matte tin-plated, solderable per J-STD-002; supports wave/solder dip (275 °C max, 10 s) and reflow processes. |
| Lead 2 | Terminal connection | Identical to Lead 1; symmetric construction eliminates orientation concerns during PCB assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| 500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without degradation when properly mounted. |
| AEC-Q101 qualification | Validated for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes let-through energy to sensitive components such as CAN transceivers or analog front-ends. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and automotive material compliance (Vishay Doc. 99912). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | DO-214AA package (SMB), 600 W PPPM, VC = 58.1 V @ 8.8 A; higher surge rating but larger footprint. | Preferred where board space allows larger SMT package and higher IEC 61000-4-5 margin is required. | Select SMBJ36CA for surface-mount designs needing higher power density and automated assembly compatibility. |
| 1.5KE36CA | DO-201AD package, 1500 W PPPM, VC = 58.1 V @ 25.4 A; through-hole, higher surge capacity, same VWM/VBR. | Used in legacy through-hole power supply inputs or high-energy industrial mains protection. | Choose 1.5KE36CA when replacing older designs or when >1 kW surge handling is mandated by system-level testing. |
Compared with SA36CAHE3/54, SMBJ36CA offers superior SMT manufacturability and slightly higher surge rating in a smaller outline, while 1.5KE36CA delivers triple the peak power in a legacy axial package - both retain identical 36 V standoff and clamping behavior but differ in thermal mass, mounting method, and PCB layout impact.

FAQ
What is the standoff voltage rating of the SA36CAHE3/54?
The SA36CAHE3/54 has a rated standoff voltage (VWM) of 36 V, meaning it remains non-conductive up to this DC or RMS voltage level under normal operation. This value is confirmed in the Vishay datasheet Document Number 88378, Table "ELECTRICAL CHARACTERISTICS", row SA36A/SA36CA. Exceeding 36 V triggers avalanche conduction to protect downstream circuitry.
Is the SA36CAHE3/54 suitable for automotive applications?
Yes, the SA36CAHE3/54 is AEC-Q101 qualified (per datasheet note on page 3), making it suitable for automotive applications including body electronics, sensor interfaces, and infotainment systems. Its DO-15 package, -55 °C to +175 °C operating range, and validated surge performance align with ISO 7637-2 and ISO 16750-2 requirements - all verified in the official Vishay qualification report referenced in Document 88378.
What does the 'HE3' suffix indicate on SA36CAHE3/54?
The 'HE3' suffix on SA36CAHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Per Vishay's ordering information (page 3), HE3 devices use matte tin-plated leads, meet UL 94 V-0 flammability, and undergo enhanced reliability screening - distinguishing them from commercial-grade E3 variants which lack automotive qualification.
How does the bidirectional configuration of SA36CAHE3/54 affect its usage?
The SA36CAHE3/54 is inherently bidirectional, with no polarity marking and symmetrical VBR in both directions (40.0–44.2 V). This allows direct placement across AC signal lines, differential buses (e.g., RS-485), or ungrounded power rails without orientation concerns. Its clamping action activates identically for positive or negative transients - a key advantage over unidirectional types like SA36A that require correct cathode alignment.
What is the maximum clamping voltage of SA36CAHE3/54 under surge conditions?
The SA36CAHE3/54 exhibits a maximum clamping voltage (VC) of 58.1 V at 8.6 A peak pulse current (IPPM) with a 10/1000 µs waveform, as specified in the "ELECTRICAL CHARACTERISTICS" table (page 2) of Vishay Document 88378. This value represents the upper voltage limit imposed on protected circuitry during standardized surge events and is critical for ensuring compatibility with 3.3 V or 5 V logic interfaces downstream.
