Product details
Overview
SA150CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-15 package, rated for 150 V stand-off voltage (VWM), 184 V clamping voltage (VC) at 2.1 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform. It provides robust overvoltage protection for automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SA150CAHE3/54 datasheet, SA150CAHE3/54 pinout, SA150CAHE3/54 application, or SA150CAHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-15 mechanical data, clamping behavior under surge conditions, and direct alternatives for ESD and load-dump protection design.
Technical Context
The SA150CAHE3/54 operates as a symmetrical avalanche diode, exhibiting identical breakdown characteristics in both directions due to its bidirectional construction. Its 184 V clamping voltage at 2.1 A IPPM ensures predictable voltage limiting during transients such as ISO 7637-2 Pulse 1 and Pulse 2b.
Designed for high-reliability environments, it features glass-passivated junctions, AEC-Q101 qualification, and a maximum operating junction temperature of +175 °C. The device maintains ≤1.0 μA reverse leakage at 150 V (VWM) and exhibits a ±5 % VBR tolerance (167–185 V at 1 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 167 V / 185 V at 1 mA - Confirmed breakdown range defining turn-on threshold |
| VC @ IPPM | 184 V at 2.1 A - Clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 500 W - Peak transient energy handling capability per single 10/1000 μs pulse |
| ID @ VWM | ≤1.0 μA - Low leakage preserves signal integrity in high-impedance circuits |
| TJ max | +175 °C - Enables operation in under-hood automotive and industrial ambient conditions |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements |
Pinout & Package
SA150CAHE3/54 uses the DO-15 (DO-204AC) axial-leaded package: 3.3–3.5 mm diameter, 6.15–6.55 mm body length, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional polarity has no marking on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Leads are interchangeable; conducts identically in either direction during overvoltage events |
| Lead 1 | Connection node | Directly interfaces with protected line (e.g., CAN_H or LIN bus); no polarity dependency |
| Lead 2 | Connection node | Connects to reference plane (e.g., chassis ground or signal return); forms low-inductance clamp path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable avalanche performance and long-term reliability under repetitive surge stress |
| 500 W peak pulse power (10/1000 μs) | Withstands automotive load-dump surges (ISO 16750-2) without degradation |
| AEC-Q101 qualification | Validated for automotive-grade deployment including temperature cycling, HTRB, and ESD testing |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., EFT bursts) |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and automotive enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/5A | Same VWM (150 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs | Select when board space is constrained and automated assembly is used. |
| P6SMB150A | Same VWM (150 V), same DO-15 package, but only commercial-grade (not AEC-Q101 qualified) | Lacks automotive qualification; not recommended for vehicle-mounted systems | Select for cost-sensitive industrial applications where AEC-Q101 is not mandated. |
Compared with SA150CAHE3/54, SMAJ150A-E3/5A offers smaller footprint but reduced surge margin, while P6SMB150A matches form-factor and voltage rating but omits automotive qualification-making SA150CAHE3/54 the sole AEC-Q101-compliant DO-15 option at 150 V.

FAQ
What is the clamping voltage of SA150CAHE3/54 and how is it measured?
The SA150CAHE3/54 has a maximum clamping voltage (VC) of 184 V, measured at a peak pulse current (IPPM) of 2.1 A using the standard 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value reflects the actual voltage seen by downstream circuitry during a defined surge event and is guaranteed across the full operating temperature range.
Is SA150CAHE3/54 suitable for automotive applications?
Yes, SA150CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, UL 94 V-0 molding, and operation up to +175 °C junction temperature-meeting requirements for engine bay and chassis-mounted ECUs subject to ISO 7637-2 and ISO 16750-2 stress profiles.
Does SA150CAHE3/54 have polarity markings?
No, SA150CAHE3/54 is a bidirectional TVS diode and carries no polarity marking on the DO-15 package. Both leads are functionally identical, allowing installation in either orientation without affecting clamping performance or circuit protection functionality.
What is the maximum reverse leakage current for SA150CAHE3/54 at rated VWM?
The SA150CAHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated stand-off voltage of 150 V (VWM), tested at 25 °C. This low leakage ensures minimal power loss and signal distortion in high-impedance sensing or communication paths.
How does the HE3 suffix affect SA150CAHE3/54 compared to E3?
The HE3 suffix on SA150CAHE3/54 indicates AEC-Q101 qualification and compliance with JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. SA150CAHE3/54 is therefore validated for automotive reliability testing including temperature cycling, HTRB, and mechanical shock-unlike the non-HE3 variants.
