Product details
Overview
SA10C-E3/73 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 500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), 12.9 V maximum clamping voltage at 29.4 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA10C-E3/73 datasheet, SA10C-E3/73 pinout, SA10C-E3/73 application, or SA10C-E3/73 equivalent, key selection criteria include bi-directional clamping capability, low clamping ratio (VC/VWM = 1.29), junction temperature range (–55 °C to +175 °C), RoHS compliance (E3 suffix), and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified at 11.1 V (min) to 12.3 V (max) under 10 mA test current. Its bi-directional architecture eliminates polarity dependency, enabling direct placement across AC-coupled or floating signal paths without orientation constraints.
The device uses glass-passivated chip junction technology for stable avalanche characteristics and low incremental surge resistance. Clamping performance is validated per 10/1000 μs waveform with 0.01 % duty cycle, and thermal derating follows a defined curve up to 175 °C junction temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and PPPM (400 W); lower peak pulse current (24.7 A) and higher clamping voltage (17.0 V) | Less effective clamping margin for 3.3 V/5 V systems due to VC/VWM = 1.70 vs. SA10C-E3/73's 1.29 | Select SMAJ10CA only when board space requires SMC (DO-214AB) surface-mount package and 400 W rating suffices |
| P6KE10CA | Higher PPPM (600 W); same VWM (10 V); larger DO-204AL (DO-15) package with longer leads and higher thermal mass | Better sustained surge handling but slower response due to higher junction capacitance (~1000 pF vs. ~500 pF for SA10C-E3/73) | Prefer P6KE10CA for high-energy lightning protection where response time is secondary to energy absorption |
Compared with SMAJ10CA and P6KE10CA, SA10C-E3/73 delivers superior clamping efficiency (lower VC/VWM), tighter VBR tolerance (±5.5 %), and AEC-Q101 validation - making it optimal for automotive and high-speed signal line protection where precision and qualification matter.

FAQ
What is the polarity configuration of SA10C-E3/73?
SA10C-E3/73 is a bi-directional TVS diode with no polarity marking on the DO-204AC package. Its symmetrical avalanche structure allows either terminal to serve as anode or cathode, enabling flexible placement across AC-coupled or floating signal paths without orientation constraints - a key advantage over uni-directional variants like SA10A-E3/73.
Does SA10C-E3/73 meet automotive qualification standards?
Yes, SA10C-E3/73 carries the HE3 suffix variant for AEC-Q101 qualification, and the E3 suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance. While SA10C-E3/73 itself is commercial-grade (E3), its identical die and construction are validated under AEC-Q101 in the SA10CHE3/73 variant - confirming suitability for automotive applications when sourced with appropriate traceability.
What is the maximum clamping voltage of SA10C-E3/73 under standard test conditions?
The maximum clamping voltage (VC) of SA10C-E3/73 is 12.9 V, measured at 29.4 A peak pulse current using the 10/1000 μs waveform. This value reflects worst-case clamping performance across temperature and process variation, ensuring protected circuitry remains within safe overvoltage margins - especially critical for 5 V logic interfaces paired with SA10C-E3/73.
Can SA10C-E3/73 be used in place of a uni-directional TVS like SA10A-E3/73?
SA10C-E3/73 can replace SA10A-E3/73 only in circuits where polarity independence is acceptable and forward conduction is not required. Unlike SA10A-E3/73, SA10C-E3/73 lacks a defined cathode band and conducts symmetrically - making it unsuitable for DC-biased lines needing unidirectional blocking. Always verify signal topology before substitution.
What packaging format is used for SA10C-E3/73?
SA10C-E3/73 is supplied in 13" diameter paper tape and reel packaging with a base quantity of 4000 units per reel (package code 73). The DO-204AC (DO-15) axial-leaded form factor supports both automated through-hole insertion and manual prototyping, with matte tin-plated leads compliant with J-STD-002 solderability requirements.
