Product details
Overview
SA60HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for overvoltage protection of sensitive electronics. It features a 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), clamping voltage of 96.8 V at 5.2 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA60HE3/73 datasheet, SA60HE3/73 pinout, SA60HE3/73 application, or SA60HE3/73 equivalent, this device is selected for robust ESD and surge protection on DC power rails and signal lines where fast response (<1 ns), low clamping ratio, and high surge current tolerance (70 A IFSM) are required in harsh environments.
Technical Context
The SA60HE3/73 operates as a uni-directional avalanche diode, conducting only in reverse bias above its breakdown threshold to shunt transient energy to ground. Its glass-passivated junction ensures stable VBR and low leakage (<1.0 µA at 60 V), while its 175 °C max junction temperature supports operation in under-hood automotive locations.
It delivers 500 W peak pulse power per 10/1000 µs waveform with 0.01 % duty cycle, and exhibits 96.8 V clamping voltage at rated IPPM - enabling reliable protection of 60 V-rated systems against ISO 7637-2 and IEC 61000-4-5 transients without overstressing downstream components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 60 V systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Tight breakdown window ensures predictable turn-on and avoids premature clamping. |
| VC @ IPPM | 96.8 V at 5.2 A - Clamping voltage during 10/1000 µs surge; limits stress on protected ICs to ≤97 V. |
| PPPM | 500 W - Peak transient power handling capability; supports common automotive surge test levels. |
| IFSM | 70 A - Non-repetitive forward surge rating; enables survivability during load dump events. |
| TJ max | 175 °C - High junction temperature rating allows deployment in engine control units and powertrain modules. |
| Leakage ID | <1.0 µA at 60 V - Minimal standby current draw preserves battery life in always-on automotive circuits. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads, RoHS-compliant, AEC-Q101 qualified (HE3 suffix). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to system ground or low-side reference; completes clamping loop during transient events. |
| Cathode | Reverse-biased protection node | Connected to protected line (e.g., 60 V supply rail); conducts when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable VBR and long-term reliability under thermal cycling and humidity stress. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| 500 W peak pulse power (10/1000 µs) | Meets ISO 7637-2 Pulse 1, 2a, 3a/b and IEC 61000-4-5 Level 3 surge immunity requirements. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in MOSFETs/ICs. |
| Solderable per J-STD-002/JESD 22-B102 | Compatible with standard reflow and wave soldering processes; matte tin plating prevents dewetting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60A-E3/52 | Same VWM (60 V), lower PPPM (400 W), SMA package (surface-mount), no AEC-Q101 qualification. | Preferred for space-constrained PCBs where automotive qualification is not required. | Select when board area is limited and automotive reliability certification is unnecessary. |
| 1.5KE60A | Same VWM (60 V), higher PPPM (1500 W), DO-201AD package, higher VC (100 V), no AEC-Q101. | Suitable for industrial mains-powered equipment needing higher surge margin but less stringent qualification. | Choose for non-automotive 1500 W surge protection where 100 V clamping is acceptable. |
Compared with SMA60A-E3/52 and 1.5KE60A, SA60HE3/73 uniquely combines AEC-Q101 qualification, 500 W pulse rating, and DO-15 through-hole robustness-making it optimal for automotive under-hood and chassis-mounted modules requiring proven reliability and serviceability.

FAQ
What is the breakdown voltage range of the SA60HE3/73?
The SA60HE3/73 has a specified breakdown voltage (VBR) range of 66.7 V to 73.7 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight 10.5 % tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 60 V system designs.
Is the SA60HE3/73 suitable for automotive applications?
Yes, the SA60HE3/73 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance with automotive reliability standards. Its 175 °C max junction temperature, glass-passivated junction, and qualification for temperature cycling, humidity, and mechanical shock make it suitable for engine control units, body controllers, and ADAS sensor modules.
What is the clamping voltage of SA60HE3/73 at its rated peak pulse current?
The SA60HE3/73 clamps to a maximum of 96.8 V at its rated peak pulse current (IPPM) of 5.2 A under a 10/1000 µs waveform. This value is guaranteed per datasheet Table 1 and reflects worst-case performance at TA = 25 °C, providing a firm upper bound for protected circuit voltage stress.
Does SA60HE3/73 have polarity marking, and how is it identified?
Yes, the SA60HE3/73 is a uni-directional TVS diode with polarity marking: a colored band on the cathode end. The cathode must be connected to the protected line (e.g., 60 V rail), and the anode to ground. No marking is used on bi-directional variants, but SA60HE3/73 explicitly carries the "A" suffix denoting uni-directional configuration.
What is the maximum steady-state power dissipation for SA60HE3/73?
The SA60HE3/73 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, per Figure 5 in the datasheet. In typical PCB layouts without heatsinking, derating applies - e.g., ~1.5 W at TL = 100 °C - limiting continuous leakage-related heating in high-temperature environments.
