Product details
Overview
SAC10-E3/54 from Vishay General Semiconductor is a unidirectional low-capacitance TRANSZORB® transient voltage suppressor (TVS) diode in DO-15 package, designed for clamping fast voltage transients on signal and power lines. It features a 10 V working peak inverse voltage (VWM), 11.1 V minimum breakdown voltage (VBR) at 1 mA, 16.3 V maximum clamping voltage at 5 A (VC), 500 W peak pulse power (10/1000 μs), and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the SAC10-E3/54 datasheet, SAC10-E3/54 pinout, SAC10-E3/54 application, or SAC10-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, unidirectional polarity for DC-biased lines, DO-15 thermal derating behavior, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
The SAC10-E3/54 employs a glass-passivated silicon junction optimized for rapid response (<1 ns) to ESD and lightning-induced surges. Its low incremental surge resistance ensures stable clamping under high di/dt conditions, while its 50 pF junction capacitance (at 0 V) enables use on moderate-speed signal lines without signal integrity degradation.
It is rated for 500 W non-repetitive peak pulse power per 10/1000 μs waveform with 0.01 % duty cycle, and dissipates up to 3.0 W continuously on an infinite heatsink at TL = 75 °C. The device is unidirectional, cathode-marked, and RoHS-compliant with matte tin-plated leads meeting J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for DC bias on protected line |
| VBR (min) | 11.1 V at IT = 1 mA - Confirmed breakdown initiation threshold; ensures reliable turn-on above normal operating voltage |
| VC (max) | 16.3 V at IPP = 5.0 A - Clamped voltage during surge; must remain below protected IC's absolute maximum rating |
| PPPM | 500 W (10/1000 μs) - Surge energy handling capacity; defines protection level against IEC 61000-4-5 2 Ω/12 Ω coupling network pulses |
| CJ (0 V) | 50 pF - Junction capacitance at zero bias; limits usable frequency range on high-speed data lines (e.g., RS-485, CAN) |
| TJ max. | +175 °C - Maximum junction temperature; supports operation in under-hood automotive or industrial motor drive environments |
| Polarity | Unidirectional - Requires correct orientation on DC-biased lines; not suitable for AC line protection without back-to-back configuration |
Pinout & Package
Package: DO-15 (DO-204AC), axial leaded, epoxy-molded case with cathode band marking. Dimensions: 3.3–3.5 mm diameter × 6.15–6.55 mm body length, 25.4 mm minimum lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential rail; current flows from cathode to anode during clamping |
| Cathode | High-side connection point | Marked by color band; connected to protected line; absorbs surge energy into ground path |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable breakdown characteristics and long-term reliability under repeated surge stress |
| 500 W peak pulse power (10/1000 μs) | Supports Level 4 IEC 61000-4-5 surge immunity (4 kV line-to-earth, 2 kV line-to-line) in properly designed circuits |
| 16.3 V clamping voltage at 5 A | Provides ≥2.7 V margin below typical 18 V absolute maximum rating of 12 V logic ICs and microcontrollers |
| 50 pF junction capacitance | Permits use on RS-485, CAN FD, and industrial analog sensor lines without measurable signal rise-time degradation |

| Consumer Appliance Motor Drive Control | Telecom Power Supply Input Stage |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers connected to MCU GPIOs and relay drivers. IC Role / Device Role / Timing Role: Low-leakage (5.0 μA max at VWM) TVS across motor coil terminals and control signal lines to prevent false triggering or latch-up.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same DO-214AC package; 10 V VWM, 11.1 V VBR min, 16.7 V VC at 5 A; 600 W PPPM; 100 pF CJ | Higher capacitance limits use on >1 Mbps data lines; better suited for power rail vs. signal line protection | Select SMAJ10A when higher surge rating is required and layout allows larger footprint; verify thermal pad clearance for SMA package |
| P6KE10A | DO-15 package; 10 V VWM, 11.1 V VBR min, 17.0 V VC at 5.3 A; 600 W PPPM; 110 pF CJ | Higher clamping voltage and capacitance reduce suitability for sensitive analog or high-speed digital interfaces | Choose P6KE10A only for cost-sensitive, non-critical power rail protection where PCB space is constrained and signal integrity is not a concern |
Compared with SAC10-E3/54, SMAJ10A offers higher surge rating but doubles junction capacitance, limiting high-frequency use; P6KE10A matches the DO-15 form factor but increases clamping voltage and capacitance, reducing margin for modern low-voltage ICs.

FAQ
What is the maximum clamping voltage of the SAC10-E3/54 under a 5 A transient?
The SAC10-E3/54 has a maximum clamping voltage (VC) of 16.3 V when subjected to a 5.0 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed across temperature and represents the upper voltage limit seen by downstream circuitry during surge events, ensuring compatibility with 12 V and 15 V logic systems.
Is SAC10-E3/54 suitable for bidirectional signal line protection like RS-485?
No, SAC10-E3/54 is unidirectional and cannot protect AC or bidirectional signals alone. For RS-485 or other differential lines, two SAC10-E3/54 devices must be used in back-to-back configuration (anode-to-anode), or a dedicated bidirectional TVS such as SMBJ10CA should be selected instead.
What is the junction capacitance of SAC10-E3/54 and how does it affect high-speed signal lines?
The SAC10-E3/54 exhibits 50 pF junction capacitance at 0 V bias. At typical operating voltages near VWM (10 V), capacitance drops further. This enables use on signal lines up to ~10 Mbps (e.g., CAN FD, RS-485) without significant edge distortion, though it is not recommended for USB 2.0 or HDMI interfaces.
Does SAC10-E3/54 meet automotive qualification standards such as AEC-Q200?
The SAC10-E3/54 is not AEC-Q200 qualified. While it operates from –55 °C to +175 °C and is widely used in automotive subsystems, Vishay specifies it for commercial and industrial grades. For AEC-Q200-compliant designs, consider the automotive-grade SAC10AHE3/54 variant or equivalent AEC-Q200-certified TVS devices.
How is the polarity marked on SAC10-E3/54 and why does it matter for circuit placement?
SAC10-E3/54 uses a cathode band (colored stripe) to identify the cathode terminal. Correct orientation is critical: cathode connects to the protected line, anode to ground. Reversal results in forward conduction during normal operation, causing excessive leakage, overheating, and potential failure-especially damaging in DC-biased applications.
