Product details
Overview
SA24C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for surge protection on signal and power lines. It features a 24 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), clamping voltage of 38.9 V at 12.9 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA24C-E3/54 datasheet, SA24C-E3/54 pinout, SA24C-E3/54 application, or SA24C-E3/54 equivalent, this page delivers verified electrical parameters, bi-directional clamping behavior, DO-15 mechanical data, automotive-grade reliability evidence, and real-world ESD/lightning transient protection context - all critical for robust circuit hardening in industrial and automotive electronics.
Technical Context
The SA24C-E3/54 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 and low leakage (<1.0 μA at 24 V), while its 175 °C max junction temperature supports high-ambient deployments.
It delivers 500 W peak pulse power per 10/1000 μs waveform with 0.01 % duty cycle, and exhibits low incremental surge resistance - key for limiting let-through energy during fast transients like ISO 7637-2 pulses or IEC 61000-4-5 surges. No marking indicates bi-directional polarity per Vishay specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected line. |
| VBR (min/max) | 26.7 V / 29.5 V at 1 mA - tight breakdown window ensures predictable turn-on and avoids false triggering near VWM. |
| VC @ IPPM | 38.9 V at 12.9 A - clamping voltage under full-rated surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W (10/1000 μs) - surge handling capacity sufficient for automotive load-dump and telecom lightning events. |
| ID @ VWM | ≤1.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | +175 °C - enables placement near hot components (e.g., power MOSFETs, DC/DC converters) without derating. |
| AEC-Q101 | Qualified - validated for automotive under-hood and infotainment applications per stress test requirements. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads, solderable per J-STD-002/JESD 22-B102. Bi-directional - no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts bidirectionally above ±VBR - no orientation required during placement. |
| Leads (anode & cathode) | PCB interface and thermal path | Lead length ≥0.375" (9.5 mm) required for rated PD = 3.0 W; shorter leads reduce power dissipation capability. |
Key Features
| Feature | Design Value |

| AEC-Q101 qualification | Validated for automotive grade-2 (-40 °C to +125 °C ambient) operation with extended reliability testing. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes let-through voltage overshoot - critical for protecting 3.3 V or 5 V logic interfaces behind series impedance. |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance - ensures long-term solder joint integrity in vibration-prone systems. |
Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping device placed across differential or single-ended sensor lines to shunt transients before they reach ADC input or op-amp front-end. Use Value: Prevents latch-up or permanent damage to precision signal conditioning ICs by limiting voltage to ≤38.9 V during 10/1000 μs surges up to 12.9 A. | Use Scenario: Safeguarding CANH/CANL bus lines in factory automation nodes subjected to EFT and surge coupling from adjacent motor drives. IC Role / Device Role / Timing Role: Low-capacitance TVS pair (one per line) suppressing common-mode transients while preserving signal edge integrity up to 1 Mbps. Use Value: Maintains CAN physical layer compliance by clamping surges without adding >100 pF parasitic capacitance - verified via Fig. 6 in datasheet. |
| Telecom DSL Line Surge Protection | Consumer Appliance Motor Control Feedback |
Use Scenario: Shielding ADSL/VDSL line drivers and receivers from lightning-induced surges entering via telephone wiring. IC Role / Device Role / Timing Role: Primary-level protector mounted at board edge, ahead of gas discharge tube (GDT) secondary stage, absorbing initial fast-rising energy. Use Value: Fast response time (<1 ns) and 500 W rating enable it to clamp 1 kV/500 A surges (per IEC 61000-4-5) before GDT fires - reducing overall let-through voltage. | Use Scenario: Securing hall-effect sensor feedback paths in washing machine motor inverters subject to commutation spikes. IC Role / Device Role / Timing Role: Bi-directional suppressor across sensor supply and output lines, absorbing repetitive 100–200 V spikes generated by BLDC phase switching. Use Value: Withstands 70 A non-repetitive forward surge (IFSM) and 175 °C TJ max, ensuring survival in thermally constrained appliance enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24CA | Same VWM (24 V), same DO-214AC package; lower PPPM (400 W), higher VC (43.5 V @ 11.4 A). | Less robust for high-energy surges; better suited for space-constrained PCBs where SMA footprint is preferred. | Select SMAJ24CA only if board layout mandates SMD and surge threat level is limited to IEC 61000-4-2 ESD (±8 kV contact). |
| P6KE27CA | Higher VWM (27 V), larger DO-15 package; identical 500 W rating but looser VBR tolerance (29.9–33.1 V). | Marginally higher clamping voltage reduces protection margin for 24 V systems; requires revalidation of downstream IC withstand. | Choose P6KE27CA only when system VWM tolerance allows 27 V standoff and legacy DO-15 footprint compatibility is mandatory. |
Compared with SMAJ24CA and P6KE27CA, the SA24C-E3/54 offers optimal balance of precise 24 V standoff, lowest clamping voltage (38.9 V), and AEC-Q101 qualification - making it the preferred choice for new automotive and industrial designs demanding verified reliability and minimal let-through voltage.

FAQ
What is the polarity configuration of the SA24C-E3/54?
The SA24C-E3/54 is a bi-directional TVS diode with symmetrical terminal behavior - neither lead is marked as anode or cathode. It clamps transients equally in both directions above ±26.7 V, making it ideal for AC-coupled or floating signal lines. This eliminates orientation errors during assembly and simplifies design for differential or ungrounded interfaces.
Does the SA24C-E3/54 meet automotive qualification standards?
Yes, the SA24C-E3/54 is AEC-Q101 qualified, as confirmed in Vishay document 88378 (Rev. 18-Sep-12). This certification covers stress tests including HTSL, TCT, UHAST, and mechanical shock - validating its suitability for automotive powertrain, chassis, and body electronics where ambient temperatures reach 125 °C and reliability over 15+ years is required.
What is the maximum clamping voltage of the SA24C-E3/54 under rated surge conditions?
The SA24C-E3/54 has a maximum clamping voltage (VC) of 38.9 V at 12.9 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is guaranteed across temperature and represents the highest voltage seen by protected circuitry during worst-case surge events - critical for verifying compatibility with 3.3 V, 5 V, or 24 V ICs downstream.
Can the SA24C-E3/54 be used in place of a uni-directional TVS like SA24A-E3/54?
No - the SA24C-E3/54 is bi-directional and lacks polarity marking, while SA24A-E3/54 is uni-directional with a cathode band. Substituting them requires circuit review: SA24C-E3/54 may be used on AC or floating lines, but will not protect DC-biased lines where reverse blocking is needed. Always verify signal topology and biasing before replacement.
What is the RoHS and whisker resistance status of the SA24C-E3/54?
The SA24C-E3/54 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU and JESD 201 Class 1A whisker resistance. Its matte tin-plated leads resist tin whisker growth under thermal cycling and humidity, supporting long-term reliability in automotive and industrial applications where solder joint integrity is mission-critical.
