Product details
Overview
SA60CHE3/73 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 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 5.2 A peak pulse current (IPPM), and clamps to ≤96.8 V at rated surge. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the SA60CHE3/73 datasheet, SA60CHE3/73 pinout, SA60CHE3/73 application, or SA60CHE3/73 equivalent, this page delivers verified electrical specs, package dimensions, clamping behavior under surge, AEC-Q101 qualification status, and direct alternatives for automotive-grade transient suppression.
Technical Context
The SA60CHE3/73 operates as a bi-directional avalanche diode, symmetrically clamping positive and negative transients above its breakdown threshold. Its glass-passivated junction ensures stable VBR and low leakage (<1.0 μA at VWM), while its 175 °C max junction temperature supports under-hood automotive deployment.
It delivers 500 W peak pulse power per 10/1000 μs waveform with 0.01 % duty cycle, and exhibits low incremental clamping resistance-evidenced by VC − VBR = 23.1–30.1 V across IPPM-enabling effective energy diversion without overstressing downstream ICs or MOSFETs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for 48 V or 60 V nominal systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures reliable turn-on within spec; critical for timing of clamping response. |
| IPPM | 5.2 A (10/1000 μs) - Peak surge current it safely shunts without failure; determines minimum series impedance needed in protected circuit. |
| VC | ≤96.8 V - Clamped voltage at IPPM; sets upper bound on stress seen by protected device (e.g., MCU I/O or CAN transceiver). |
| PPPM | 500 W - Surge energy handling capacity; validates suitability for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3/4 tests. |
| Leakage (ID) | ≤1.0 μA at 60 V - Ultra-low reverse leakage preserves signal integrity and battery drain budget in always-on circuits. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 7.6 mm min. lead length; compatible with legacy through-hole assembly and manual repair. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case meeting UL 94 V-0; no polarity marking (bi-directional); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction terminals | No functional distinction-either lead connects to protected line; enables single-component placement across AC or differential signals. |
| Lead 1 | Terminal for PCB mounting and thermal conduction | Provides mechanical anchoring and limited heat dissipation path; requires ≥0.375" (9.5 mm) lead length for rated PD derating. |
| Lead 2 | Terminal for PCB mounting and thermal conduction | Identical to Lead 1; symmetric layout simplifies routing and eliminates orientation errors during assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces per stress test requirements. |
| Glass passivated junction | Ensures long-term VBR stability and low parameter drift over temperature and lifetime-critical for safety-critical protection functions. |
| 500 W peak pulse power (10/1000 μs) | Supports robust immunity to load dump, inductive switching spikes, and ESD events without degradation after repeated surges. |
| Low clamping ratio (VC/VBR ≈ 1.3–1.45) | Minimizes overvoltage overshoot during transient events-reducing risk of latch-up or gate oxide damage in protected MOSFETs or ICs. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-ensuring reliability in high-vibration, high-temperature automotive environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60CAHE3/A | Same VWM (60 V), same DO-204AC package, but lower PPPM (400 W vs. 500 W); slightly higher VC (103 V vs. 96.8 V). | Marginally lower surge capability; suitable where IEC 61000-4-5 Level 2 suffices but not Level 4. | Select SMA60CAHE3/A only if board space or cost constraints outweigh need for full 500 W rating. |
| 1.5KE60CA | Higher PPPM (1500 W), larger DO-201AD package, same VWM and bi-directionality; clamps at 96.8 V but with higher junction capacitance (~100 pF vs. ~30 pF). | Better energy absorption but unsuitable for high-speed data lines due to higher capacitance; requires PCB layout revision. | Choose 1.5KE60CA when protecting power rails with high-energy transients and no signal integrity constraints. |
Compared with SMA60CAHE3/A and 1.5KE60CA, SA60CHE3/73 uniquely balances 500 W surge rating, low clamping voltage, DO-204AC footprint, and AEC-Q101 qualification-making it optimal for space-constrained, automotive-grade signal line protection where both reliability and form factor matter.

FAQ
What is the maximum clamping voltage of SA60CHE3/73 at its rated peak pulse current?
The SA60CHE3/73 clamps to a maximum of 96.8 V at its specified peak pulse current (IPPM) of 5.2 A under a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88378) and defines the upper voltage limit imposed on protected circuitry during surge events. Maintaining VC below 100 V ensures compatibility with 75 V-rated interface ICs commonly used in automotive and industrial designs.
Is SA60CHE3/73 suitable for bi-directional signal line protection?
Yes, SA60CHE3/73 is explicitly designed for bi-directional applications, as indicated by the "CA" suffix and confirmed in Vishay's documentation. Its symmetrical avalanche structure provides identical clamping behavior for both polarities, making it ideal for protecting differential buses (e.g., RS-485, LIN), AC-coupled sensors, or any line subject to reversible transients. No polarity marking is present on the DO-204AC package, reinforcing its bidirectional functionality.
Does SA60CHE3/73 meet automotive reliability standards?
Yes, SA60CHE3/73 carries the HE3 suffix, which denotes AEC-Q101 qualification per Vishay's ordering information and mechanical data section. It has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-validating its use in engine compartments, transmission control units, and other automotive domains where ambient temperatures reach 125 °C and beyond.
What is the reverse leakage current of SA60CHE3/73 at its stand-off voltage?
The reverse leakage current (ID) of SA60CHE3/73 is guaranteed at ≤1.0 μA when biased at its 60 V stand-off voltage (VWM) and tested at 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes quiescent current draw in battery-powered systems-critical for always-on automotive modules such as door handle proximity sensors or tire pressure monitors.
Can SA60CHE3/73 be used in place of uni-directional TVS diodes like SA60A?
No-SA60CHE3/73 is bi-directional and must not replace uni-directional types like SA60A in DC-biased circuits. While both share VWM = 60 V, SA60A conducts forward current during positive transients only and blocks reverse voltage entirely, whereas SA60CHE3/73 clamps in both directions. Substituting them risks unintended conduction or inadequate protection in circuits with defined polarity, such as 12 V supply rail protection.
