Product details
Overview
SA10-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 29.4 A peak pulse current, 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA10-E3/54 datasheet, SA10-E3/54 pinout, SA10-E3/54 application, or SA10-E3/54 equivalent, this device is selected for robust ESD and surge protection in automotive body electronics, industrial sensor interfaces, and DC power input stages where fast response (<1 ps), low clamping ratio (VC/VBR ≈ 1.53), and 175 °C junction temperature capability are critical.
Technical Context
The SA10-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling precise VBR tolerance (±5 %) and stable thermal coefficient (10 %/°C). Its unidirectional polarity uses a cathode band marking and supports reverse-biased clamping only - forward conduction is limited to 3.5 V at 100 A surge.
It delivers 500 W peak pulse power under standardized 10/1000 µs waveform conditions, with derating above 25 °C ambient per Fig. 2 and 3.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature, validated per JESD 22-B102 solderability and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V systems. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Tight breakdown window ensures predictable turn-on during transients without premature leakage. |
| VC @ IPPM | 17.0 V at 29.4 A - Clamps induced surges to safe levels for downstream ICs like MCUs and CAN transceivers. |
| PPPM | 500 W - Sustains high-energy lightning-induced surges (IEC 61000-4-5 Level 4) without failure. |
| IFSM | 70 A - Withstands 10 ms half-sine surge events common in automotive load-dump scenarios. |
| TJ max | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal derating. |
| Package | DO-204AC (DO-15) - Industry-standard through-hole package with 0.432 g unit weight, RoHS-compliant matte tin leads. |
Pinout & Package
SA10-E3/54 is a two-terminal unidirectional TVS diode in DO-204AC (DO-15) molded epoxy package. The cathode is marked by a color band on the body; anode is unmarked. Leads are matte tin-plated and compliant with J-STD-002 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to system ground or low-side return path; establishes reference for clamping action. |
| Cathode | Clamping output / Surge sink node | Connected to protected line (e.g., 12 V rail); conducts transient energy to ground when VIN exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| 500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive applications without external series impedance. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and board-level reliability per stress test plan. |
| Low incremental clamping resistance | Enables tight VC – VBR margin (5.9 V), minimizing voltage overshoot during fast transients. |
| JESD 201 Class 1A whisker resistance | Prevents tin whisker growth under thermal cycling, ensuring long-term solder joint integrity in safety-critical systems. |

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-E3/57 (Vishay) | Same VWM (10 V), but SMA package (DO-214AC); lower PPPM = 400 W; 1000x smaller footprint. | Preferred for space-constrained PCBs; not suitable for through-hole assembly or high-reliability mechanical retention. | Select SMAJ10A-E3/57 only if surface-mount layout and thermal management via copper pour are feasible. |
| 1N6105A (ON Semiconductor) | Identical DO-204AC package and VWM/VBR specs; same 500 W rating; but not AEC-Q101 qualified and higher VC = 17.5 V. | Limited to commercial/industrial use; unsuitable for automotive qualification programs requiring traceable AEC-Q101 test reports. | Choose 1N6105A only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMAJ10A-E3/57 and 1N6105A, SA10-E3/54 uniquely combines AEC-Q101 qualification, through-hole mechanical robustness, and 17.0 V clamping in a legacy-compatible DO-15 footprint - making it the preferred choice for automotive Tier-1 production and industrial field-replaceable modules.

FAQ
What is the clamping voltage of SA10-E3/54 at its rated peak pulse current?
The SA10-E3/54 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 29.4 A under the standard 10/1000 µs waveform. This value is measured per Figure 7 in the Vishay datasheet 88378 and reflects worst-case performance at TA = 25 °C. The SA10-E3/54 maintains this clamping performance across its full operating temperature range due to its stable avalanche junction design.
Is SA10-E3/54 suitable for automotive applications?
Yes, SA10-E3/54 is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade product documentation. It meets stress test requirements including temperature cycling, mechanical shock, and board-level reliability validation. Its 175 °C maximum junction temperature and DO-204AC package with JESD 201 Class 1A whisker resistance make SA10-E3/54 appropriate for under-hood and body-control module deployments.
What does the "E3/54" suffix indicate in SA10-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/54" indicates the preferred package code for 13-inch paper tape and reel packaging, with a base quantity of 4000 units per reel. This ordering format is confirmed in the Vishay datasheet 88378 Section "ORDERING INFORMATION".
How does SA10-E3/54 differ from bi-directional variants like SA10CA?
SA10-E3/54 is unidirectional with cathode marking and clamps only in reverse bias; SA10CA is bi-directional with no polarity marking and clamps symmetrically in both directions. SA10-E3/54 has lower leakage at VWM (1.0 µA vs. 5.0 µA for SA10CA) and is used where DC polarity is fixed, such as 12 V power rails. SA10-E3/54 cannot replace SA10CA in AC-coupled or bidirectional signal line protection without circuit redesign.
What is the maximum steady-state power dissipation for SA10-E3/54?
The SA10-E3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C, as specified in the "MAXIMUM RATINGS" table of Vishay datasheet 88378. Derating is required above 75 °C per Figure 5, reaching zero dissipation at 175 °C junction temperature. This rating applies only to continuous DC or low-frequency operation - not to transient surge conditions.
