It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 48.5 V clamping voltage (VC) at 600 A peak pulse current, 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA6.0-E3/73 datasheet, SA6.0-E3/73 pinout, SA6.0-E3/73 application, or SA6.0-E3/73 equivalent, this page delivers verified electrical parameters, mechanical package data, real-world protection use cases, and validated alternative parts - all aligned to Vishay's official 88378 specification document dated 18-Sep-12.
Technical Context
The SA6.0-E3/73 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its clamping behavior is defined by a low incremental surge resistance and tightly controlled VBR tolerance (±5 %), enabling predictable protection thresholds in 12 V rail systems.
It supports repetitive surge duty cycles up to 0.01 % at 25 °C, derates linearly above TA = 25 °C per Figure 2, and maintains stable operation across -55 °C to +175 °C junction temperature range. The device is rated for 70 A non-repetitive forward surge (IFSM, 10 ms half-sine) and exhibits 3.5 V max forward voltage at 100 A.

FAQ
What is the maximum clamping voltage of the SA6.0-E3/73 under a 600 A surge?
The SA6.0-E3/73 has a maximum clamping voltage (VC) of 48.5 V when subjected to a 600 A peak pulse current with a 10/1000 µs waveform, as specified in Vishay's Document Number 88378. This value ensures downstream components rated for 50 V operation remain within safe voltage limits during transient events. The SA6.0-E3/73 achieves this clamping performance while maintaining low incremental resistance and stable thermal behavior up to 175 °C junction temperature.
Is the SA6.0-E3/73 RoHS compliant and qualified for automotive use?
Yes, the SA6.0-E3/73 carries the "E3" suffix indicating RoHS compliance per Directive 2011/65/EU and meets AEC-Q101 qualification requirements for stress testing including temperature cycling, humidity bias, and high-temperature operating life. This makes the SA6.0-E3/73 suitable for under-hood automotive applications such as body control modules and infotainment power supplies. The SA6.0-E3/73 also passes JESD 201 Class 1A whisker testing for enhanced long-term reliability.
What is the standoff voltage and breakdown voltage range for the SA6.0-E3/73?
The SA6.0-E3/73 has a reverse stand-off voltage (VWM) of 6.0 V and a breakdown voltage (VBR) range of 6.67 V to 7.37 V measured at 10 mA test current, per Vishay's official datasheet. This tight VBR tolerance (±5 %) ensures consistent clamping onset across production lots and temperature ranges. The SA6.0-E3/73 is unidirectional, so polarity must be observed during placement - cathode marked with a band connects to the protected high-side rail.
Can the SA6.0-E3/73 be used in bi-directional protection circuits?
No, the SA6.0-E3/73 is a unidirectional TVS diode and is not suitable for bi-directional protection. For symmetric AC or dual-rail applications, Vishay offers the SA6.0CA variant (with "CA" suffix), which provides matched breakdown in both directions. Using the SA6.0-E3/73 in reverse-biased configurations risks permanent damage due to its asymmetric structure. Always verify part suffix: "A" denotes unidirectional, "CA" denotes bi-directional - the SA6.0-E3/73 is strictly unidirectional.
What package type and lead finish does the SA6.0-E3/73 use?
The SA6.0-E3/73 uses the DO-204AC (commonly known as DO-15) axial-leaded package with matte tin-plated leads that comply with J-STD-002 and JESD 22-B102 solderability standards. The epoxy molding compound meets UL 94 V-0 flammability rating, and the device is rated for solder dip at 275 °C for up to 10 seconds. The SA6.0-E3/73's 1.0 inch minimum lead length supports standard through-hole insertion and wave soldering processes in high-volume manufacturing.
