Product details
Overview
SA60CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor diode in DO-15 package, rated for 60 V standoff voltage (VWM), 66.7–73.7 V breakdown (VBR), 500 W peak pulse power (10/1000 µs), 5.2 A peak pulse current (IPPM), and 96.8 V clamping voltage (VC) at IPPM. It protects signal lines and power rails in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the SA60CAHE3/54 datasheet, SA60CAHE3/54 pinout, SA60CAHE3/54 application, or SA60CAHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-15 mechanical data, clamping behavior under 10/1000 µs surge, and direct alternatives with documented VBR, VC, and packaging differences.
Technical Context
The SA60CAHE3/54 operates as a symmetrical silicon avalanche diode, exhibiting identical VBR and clamping characteristics in both directions due to its bidirectional construction. Its 500 W peak pulse rating is defined per 10/1000 µs waveform with 0.01 % duty cycle, and it maintains stable performance across -55 °C to +175 °C junction temperature range.
It features glass-passivated junction technology, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60CAHE3/A | Same VWM/VBR/VC, but SMA (DO-214AC) surface-mount package; 1.5 W steady-state rating vs. 3.0 W for SA60CAHE3/54 | Requires PCB redesign for SMT assembly; lower thermal mass limits sustained surge repetition rate | Select when board space is constrained and thermal management via copper pour compensates for lower PD |
| P6KE60CA | Same VWM/VBR/VC, DO-15 package, but non-AEC-Q101; 5.0 W steady-state rating; higher IPPM (6.8 A) | Lacks automotive qualification; suitable for commercial/industrial use only; higher surge margin but larger footprint than required | Select for cost-sensitive non-automotive designs where AEC-Q101 is not mandated and higher IPPM adds safety margin |
Compared with SMA60CAHE3/A and P6KE60CA, the SA60CAHE3/54 uniquely combines AEC-Q101 qualification, 3.0 W power dissipation, and axial-leaded DO-15 form factor-making it optimal for through-hole automotive modules requiring proven reliability and serviceability.

FAQ
What is the clamping voltage of SA60CAHE3/54 at its rated peak pulse current?
The SA60CAHE3/54 has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 5.2 A under the standard 10/1000 µs waveform. This value is measured per Figure 9 in Vishay document 88378 and ensures downstream circuitry remains below safe voltage thresholds during surge events. The SA60CAHE3/54 maintains this clamping performance across its full operating temperature range.
Is SA60CAHE3/54 suitable for automotive applications?
Yes, the SA60CAHE3/54 is AEC-Q101 qualified (confirmed by the HE3 suffix), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction, and validated reliability testing meet stringent automotive environmental and lifetime requirements. The SA60CAHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "CA" suffix indicate in SA60CAHE3/54?
The "CA" suffix in SA60CAHE3/54 denotes a bidirectional transient voltage suppressor configuration, meaning the device provides symmetrical clamping in both polarities with identical VBR and VC characteristics. Unlike unidirectional "A" variants, SA60CAHE3/54 has no polarity marking and is used where AC signals, differential buses, or undefined voltage polarity require protection without orientation dependency.
How does the DO-15 package of SA60CAHE3/54 compare to SMA in thermal performance?
The DO-15 package of SA60CAHE3/54 provides 3.0 W steady-state power dissipation at TL = 75 °C (per Figure 5), exceeding the 1.5 W rating of the SMA (DO-214AC) variant. Its axial-leaded construction allows direct heatsinking via lead bending and offers superior thermal mass for handling repetitive surges. The SA60CAHE3/54's DO-15 form factor also enables easier manual rework and higher creepage distances than surface-mount alternatives.
What is the maximum reverse leakage current of SA60CAHE3/54 at its standoff voltage?
The SA60CAHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 60 V standoff voltage (VWM), as specified in Table 1 of Vishay document 88378. This low leakage ensures minimal power loss in standby mode and prevents false triggering in high-impedance sensing circuits. The value is guaranteed at TA = 25 °C and remains within acceptable limits up to +125 °C per derating curves.
