Product details
Overview
SA60HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. 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-grade reliability.
For engineers reviewing the SA60HE3/54 datasheet, SA60HE3/54 pinout, SA60HE3/54 application, or SA60HE3/54 equivalent, this device is selected for robust ESD and surge protection in 12 V/24 V automotive subsystems, industrial I/O interfaces, and DC power input stages where fast response (<1 ns), low clamping ratio, and high surge current tolerance are critical.
Technical Context
The SA60HE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling stable reverse-biased clamping behavior under transient stress. Its uni-directional polarity uses a cathode band marking, and it conducts only during reverse overvoltage events-forward conduction is limited to 3.5 V at 100 A surge.
It is rated for 70 A non-repetitive forward surge current (IFSM, 10 ms half-sine), 3.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and operates across –55 °C to +175 °C junction temperature range-making it suitable for under-hood and industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; sets safe DC rail margin for 12 V/24 V systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 96.8 V at 5.2 A (10/1000 µs) - Clamping voltage defines worst-case protected-circuit stress during 500 W surge event. |
| IPPM | 5.2 A - Peak pulse current capability directly supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity testing. |
| PPPM | 500 W - Peak pulse power rating enables protection against repetitive lightning-induced surges with 0.01% duty cycle. |
| TJ max | +175 °C - High junction temperature rating allows placement near heat sources in engine control units and motor drives. |
| AEC-Q101 | Qualified - Meets automotive stress-test requirements for temperature cycling, HTRB, and surge endurance per JESD47. |
Pinout & Package
SA60HE3/54 is housed in a DO-204AC (DO-15) molded epoxy package with axial leads. The cathode is marked by a color band on the body; anode and cathode terminals are unambiguous for PCB layout and polarity-sensitive placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward bias; tied to lower-potential side of protected circuit | Connects to ground or low-side return path in uni-directional TVS configuration; must be routed with low-inductance trace. |
| Cathode (banded end) | Clamping node; connected to line under protection | Placed between protected signal/power line and system ground; absorbs surge energy by avalanching into low-impedance state. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| 500 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 surge immunity up to 1 kV open-circuit / 0.5 kA short-circuit test levels. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules requiring zero-defect field performance. |
| Matte tin-plated leads | Guarantees solderability per J-STD-002 and JESD 22-B102; compatible with lead-free reflow and wave soldering. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving clamping precision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60A-E3/52 (Vishay) | Same VWM/VBR/VC specs but in SMA (DO-214AC) surface-mount package; 1.0 W lower PD (2.0 W vs. 3.0 W). | Preferred for space-constrained PCBs; less suited for high-temperature through-hole mounting near heat sources. | Select SMA60A-E3/52 when board real estate is limited and thermal management via copper pour is feasible. |
| 1.5KE60A (ON Semiconductor) | Same VWM and PPPM, but larger DO-201AD package; higher IFSM (100 A vs. 70 A); no AEC-Q101 qualification. | Better for high-energy industrial surges; not validated for automotive qualification requirements. | Choose 1.5KE60A for cost-sensitive industrial power supplies where AEC-Q101 is not mandated. |
Compared with SMA60A-E3/52 and 1.5KE60A, SA60HE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole robustness, and 3.0 W steady-state dissipation-making it optimal for automotive and harsh-environment designs requiring proven reliability and mechanical stability.

FAQ
What is the maximum clamping voltage of SA60HE3/54 under standard surge conditions?
The SA60HE3/54 exhibits a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 5.2 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during a 500 W transient event. Designers use this parameter to verify that downstream ICs remain within absolute maximum ratings during surge stress.
Is SA60HE3/54 suitable for bi-directional signal line protection?
No, SA60HE3/54 is a uni-directional TVS diode and is not rated for bi-directional operation. Its cathode band indicates polarity, and it only clamps in reverse bias. For bi-directional protection-such as AC lines or differential data buses-Vishay's SA60CA or equivalent bi-directional variants must be used. Using SA60HE3/54 on bidirectional signals risks forward conduction and failure during positive half-cycles.
Does SA60HE3/54 meet RoHS and lead-free soldering requirements?
Yes, SA60HE3/54 carries the HE3 suffix, indicating RoHS-compliant construction and matte tin-plated leads qualified for lead-free soldering per J-STD-002 and JESD 22-B102. It also meets JESD 201 Class 2 whisker resistance, ensuring long-term reliability in high-vibration automotive applications where tin whisker growth could cause latent shorts.
What is the significance of the "/54" in SA60HE3/54?
The "/54" in SA60HE3/54 denotes the preferred package code per Vishay's ordering nomenclature, specifying 13-inch diameter paper tape and reel packaging with a base quantity of 4000 units. This format enables automated pick-and-place assembly and is standard for high-volume manufacturing. The "HE3" portion confirms AEC-Q101 qualification and RoHS compliance.
How does SA60HE3/54 perform under elevated ambient temperatures?
SA60HE3/54 maintains specified electrical characteristics up to +175 °C junction temperature, with derating applied above 25 °C ambient per Figure 2 in the datasheet. At 100 °C case temperature, its peak pulse power drops to ~65% of rated 500 W, and VBR shifts predictably (+0.071%/°C). This behavior is fully characterized and supports thermal design in under-hood automotive modules.
