Product details
Overview
SA60CHE3/54 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 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), 5.2 A peak pulse current (IPPM), and 96.8 V maximum clamping voltage (VC) - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SA60CHE3/54 datasheet, SA60CHE3/54 pinout, SA60CHE3/54 application, or SA60CHE3/54 equivalent, this part is evaluated for bi-directional overvoltage protection in automotive-grade (AEC-Q101 qualified), industrial, and telecom systems where low-leakage (<1.0 µA at VWM), fast response (<1 ns), and stable clamping under repetitive surge conditions are required.
Technical Context
The SA60CHE3/54 operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping across temperature (–55 °C to +175 °C).
It delivers 500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C per Vishay's Fig. 2, and supports steady-state dissipation up to 3.0 W on an infinite heatsink at TL = 75 °C. The device exhibits no polarity marking - consistent with bi-directional TVS construction - and meets JESD 22-B106 solderability (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 60 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 66.7–73.7 V at 1 mA - Avalanche onset range; ensures reliable triggering during transient events without premature conduction. |
| VC (Clamping) | 96.8 V at IPPM - Maximum voltage seen by downstream components during 5.2 A transient; determines minimum IC withstand rating. |
| IPPM | 5.2 A (10/1000 µs) - Peak surge current capability; sets protection margin against common lightning/inductive-spike waveforms. |
| PPPM | 500 W - Peak pulse power handling; enables robust suppression of high-energy transients without thermal runaway. |
| ID (Leakage) | <1.0 µA at 60 V - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |

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), identical DO-214AC (SMA) package; slightly higher VC (98.0 V) and lower IPPM (4.9 A); RoHS/AEC-Q101 compliant. | Surface-mount alternative for space-constrained PCBs; requires rework of footprint and thermal pad design. | Select SMA60CAHE3/A when board real estate is limited and SMT assembly is preferred over through-hole DO-15. |
| P6KE60CA | Same VWM (60 V), larger DO-204AL (DO-15) variant; identical 500 W rating but higher VC (100 V) and lower TJ max. (150 °C); not AEC-Q101 qualified. | General-purpose industrial use only; unsuitable for automotive due to lack of AEC-Q101 validation and reduced thermal margin. | Choose P6KE60CA only for cost-sensitive non-automotive applications where extended temperature operation is not required. |
