Product details
Overview
SA11C-E3/54 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 500 W peak pulse power (10/1000 μs), 18.2 V maximum clamping voltage at 27.5 A peak pulse current, and 11 V stand-off voltage with ≤1.0 μA reverse leakage. It is AEC-Q101 qualified and used in automotive sensor interface protection.
For engineers reviewing the SA11C-E3/54 datasheet, SA11C-E3/54 pinout, SA11C-E3/54 application, or SA11C-E3/54 equivalent, this page delivers verified electrical parameters, polarity behavior, clamping performance under standardized surge waveforms, and validated alternatives for ESD and load-switching transient suppression in industrial and automotive systems.
Technical Context
The SA11C-E3/54 operates as a bi-directional avalanche diode, symmetrically clamping both positive and negative transients above its breakdown voltage range of 12.2 V to 13.5 V at 1.0 mA test current. Its low incremental clamping voltage (VC = 18.2 V at IPPM = 27.5 A) ensures tight voltage limiting during 10/1000 μs surges.
It exhibits no polarity marking per datasheet, confirming true bi-directional symmetry, and maintains stable operation across -55 °C to +175 °C junction temperature. The device's 500 W peak pulse rating is derated linearly above 25 °C ambient per Figure 2, and it supports repetitive surge duty cycles up to 0.01 %.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11CA | Same VWM (11 V), identical DO-214AC package; lower PPPM (400 W), higher VC (18.5 V at 24.9 A) | Less robust for high-energy surges; suitable where space constraints favor SMC footprint over DO-15 leaded form factor | Select SMAJ11CA only when board area is constrained and surge threat level is limited to IEC 61000-4-2 Level 4 ESD or low-duty-cycle transients |
| P6KE11CA | Same VWM (11 V), DO-204AC package; lower PPPM (600 W nominal but derated to 500 W at TA > 25 °C); higher VC (18.2 V at 27.5 A same) | Higher junction capacitance (~200 pF vs. ~100 pF for SA11C-E3/54), limiting use in >1 MHz signal lines | Prefer P6KE11CA only if legacy design reuse mandates identical pinout and thermal profile, accepting higher parasitic capacitance |
Compared with SMAJ11CA and P6KE11CA, SA11C-E3/54 delivers optimal balance of low clamping voltage, AEC-Q101 qualification, and DO-204AC manufacturability-making it preferred for new automotive and industrial designs requiring proven reliability and consistent surge response.

FAQ
What is the polarity configuration of SA11C-E3/54?
The SA11C-E3/54 is a bi-directional TVS diode with no polarity marking on the DO-204AC package. Both terminals behave identically under positive or negative transients, enabling flexible PCB placement without orientation constraints. This symmetry is confirmed in the Vishay datasheet section "Polarity: no marking on bi-directional types" and validated by identical VBR and VC specifications in both directions.
Does SA11C-E3/54 meet automotive qualification standards?
Yes, SA11C-E3/54 is explicitly AEC-Q101 qualified per the Vishay datasheet revision 18-Sep-12, footnote (1) on page 3. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making SA11C-E3/54 suitable for automotive body electronics, powertrain sensors, and ADAS modules where field reliability is critical.
What is the maximum clamping voltage of SA11C-E3/54 under surge conditions?
The maximum clamping voltage of SA11C-E3/54 is 18.2 V, measured at 27.5 A peak pulse current using the standardized 10/1000 μs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table on page 2 of the Vishay datasheet and represents the upper bound of voltage seen by protected circuitry during worst-case transient events.
Can SA11C-E3/54 be used in place of a unidirectional TVS like SA11A-E3/54?
No-SA11C-E3/54 is bi-directional and lacks a defined cathode, while SA11A-E3/54 is unidirectional with a marked cathode band and forward voltage drop (VF = 3.5 V at 100 A). Substituting SA11C-E3/54 for SA11A-E3/54 in DC-biased circuits may cause unintended conduction; always verify circuit topology and polarity requirements before interchange.
What is the lead finish and soldering compatibility of SA11C-E3/54?
SA11C-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. It supports solder dip at 275 °C for up to 10 seconds per JESD 22-B106, and the E3 suffix confirms compliance with JESD 201 Class 1A whisker testing-ensuring long-term interconnect reliability in automated assembly processes.
