Product details
Overview
SA36CAHE3/53 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 stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 58.1 V maximum clamping voltage at 8.6 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA36CAHE3/53 datasheet, SA36CAHE3/53 pinout, SA36CAHE3/53 application, or SA36CAHE3/53 equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and telecom DC power rails where bidirectional clamping, low leakage (<1.0 μA at VWM), and high surge current tolerance are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (40.0–44.2 V), clamping behavior (VC = 58.1 V @ 8.6 A), and temperature coefficient (+41 mV/°C). Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns) to transient events.
The device complies with AEC-Q101 stress testing for automotive reliability and uses matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its DO-15 package supports manual or wave soldering up to 275 °C for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 36 V nominal systems. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - Confirmed breakdown range ensures reliable triggering without premature conduction under normal operation. |
| VC @ IPPM | 58.1 V at 8.6 A - Clamping voltage during 10/1000 μs surge; limits downstream voltage stress to ≤58.1 V under rated 500 W pulse. |
| PPPM | 500 W - Peak pulse power handling per 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω). |
| ID @ VWM | <1.0 μA - Reverse leakage at 36 V; minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and mechanical shock per AEC standard. |
Pinout & Package
SA36CAHE3/53 is housed in a DO-15 (DO-204AC) axial-leaded package with no polarity marking-consistent with bidirectional TVS construction. Leads are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional avalanche junction | Either lead serves as anode or cathode depending on transient polarity; symmetrical clamping eliminates orientation constraints during PCB placement. |
| Lead 1 / Lead 2 | Current-carrying terminals | Both leads conduct surge current equally in either direction; no internal series resistance or directional bias-enables direct line-to-line or line-to-ground protection. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature, critical for consistent clamping in safety-critical systems. |
| 500 W peak pulse power (10/1000 μs) | Withstands repetitive surge events up to 0.01% duty cycle-supports protection in motor drive feedback loops and relay coil snubbing. |
| AEC-Q101 qualified | Validated for automotive electronics including engine control units, ADAS sensors, and body control modules requiring long-term field reliability. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving protection margin for sensitive ICs. |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical encapsulation suitable for enclosed industrial and automotive harness assemblies. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

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 | Same VWM (36 V), higher PPPM (600 W), SMB package (surface-mount), lower VC (58.1 V vs. 59.0 V) | Preferred for space-constrained PCBs; requires reflow-compatible layout and lacks axial-leaded mechanical robustness. | Select SMBJ36CA when board area is limited and automated assembly is used; verify thermal relief for 600 W pulses. |
| P6KE36CA | Same VWM (36 V), same DO-15 package, lower PPPM (600 W), higher VC (64.0 V), no AEC-Q101 qualification | Acceptable for commercial/industrial use but not validated for automotive temperature cycling or humidity testing. | Choose P6KE36CA for cost-sensitive non-automotive designs where AEC-Q101 is not mandated and 64.0 V clamping is acceptable. |
Compared with SA36CAHE3/53, SMBJ36CA offers higher surge rating in a compact SMT form but sacrifices mechanical mounting flexibility, while P6KE36CA provides legacy DO-15 compatibility without automotive qualification or optimized clamping performance.

FAQ
What is the clamping voltage of SA36CAHE3/53 and how is it measured?
The SA36CAHE3/53 has a maximum clamping voltage (VC) of 58.1 V at 8.6 A peak pulse current (IPPM), tested with a 10/1000 μs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during a standardized surge event and is confirmed in the Vishay datasheet Document Number 88378, page 2.
Is SA36CAHE3/53 suitable for automotive applications?
Yes, SA36CAHE3/53 is AEC-Q101 qualified (note on page 3 of datasheet 88378), meaning it has passed stress tests for high-temperature operating life, temperature cycling, unbiased HAST, and mechanical shock-making it appropriate for under-hood and cabin electronics such as body control modules and sensor interfaces where SA36CAHE3/53 is deployed.
Does SA36CAHE3/53 have polarity markings?
No, SA36CAHE3/53 is a bidirectional TVS diode and carries no color band or marking-its symmetrical construction means either lead functions identically regardless of applied transient polarity. This simplifies PCB layout and eliminates orientation errors during assembly of SA36CAHE3/53.
What is the maximum operating temperature for SA36CAHE3/53?
The SA36CAHE3/53 has a maximum junction temperature (TJ) of +175 °C, enabling reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. Derating curves in Figure 2 of datasheet 88378 define safe power dissipation limits above 25 °C ambient.
How does SA36CAHE3/53 differ from unidirectional SA36AHE3/53?
SA36CAHE3/53 is bidirectional with symmetrical VBR (40.0–44.2 V) and clamping in both directions, while SA36AHE3/53 is unidirectional with cathode marking and conducts only in reverse bias. SA36CAHE3/53 is used where AC-coupled or floating lines require protection without polarity constraints-unlike SA36AHE3/53 which suits DC rails with defined ground reference.
