Product details
Overview
SA10HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for circuit-level ESD and surge protection. 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 reliability.
For engineers reviewing the SA10HE3/54 datasheet, SA10HE3/54 pinout, SA10HE3/54 application, or SA10HE3/54 equivalent, this device is selected for robust overvoltage protection on DC power rails and low-speed signal lines where fast response (<1 ns), low clamping ratio, and high surge immunity are required in automotive body electronics, industrial sensors, and power supply inputs.
Technical Context
The SA10HE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling precise breakdown triggering and stable clamping under repetitive transients. Its uni-directional polarity uses a cathode band marking and supports forward conduction only during reverse overvoltage events - not intended for rectification.
It delivers 500 W peak pulse power per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, with maximum junction temperature of +175 °C and 70 A non-repetitive forward surge capability (IFSM). Clamping performance is validated at IPPM = 29.4 A, yielding VC = 17.0 V - a clamping ratio (VC/VWM) of 1.70.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 11.1–12.3 V at IT = 1 mA - precise avalanche initiation range ensuring predictable turn-on during transients |
| VC (Clamping Voltage) | 17.0 V at IPPM = 29.4 A - limits downstream voltage stress during 500 W surge, critical for IC-level protection |
| PPPM (Peak Pulse Power) | 500 W (10/1000 μs) - sustains high-energy lightning or inductive-switching surges without failure |
| ID (Reverse Leakage) | 1.0 μA at VWM = 10 V - negligible standby power loss and minimal impact on high-impedance circuits |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and thermally constrained enclosures |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
Pinout & Package
SA10HE3/54 is housed in a DO-204AC (DO-15) molded epoxy package with matte tin-plated leads. The cathode is marked by a color band on the case; the anode is unmarked. Leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode (unmarked end) | Reference / return path | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 500 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 (4 kV) surges on 2 Ω source impedance without degradation |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, chassis, and body control modules requiring zero-failure field performance |
| Low incremental surge resistance | Enables tight clamping (VC − VBR = 5.7 V) - reduces voltage overshoot seen by protected ICs |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance - suitable for lead-free reflow and high-reliability assembly |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |

Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load-dump and jump-start transients in door modules and lighting controllers. IC Role / Device Role / Timing Role: Uni-directional TVS placed between LIN line and ground, clamping spikes within nanoseconds to prevent latch-up or gate oxide damage. Use Value: With VWM = 10 V and VC = 17.0 V, it safeguards 12 V nominal systems while staying below the 20 V absolute maximum rating of common LIN ICs. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop drivers) from ESD and inductive kickback in factory automation sensors. IC Role / Device Role / Timing Role: Mounted directly at connector entry point, acting as first-line transient shunt before signal conditioning circuitry. Use Value: 1.0 μA leakage at 10 V ensures no measurable error in precision current-loop accuracy; 500 W rating handles relay-coil energy discharge. |
| DC Power Supply Input | Consumer Appliance Motor Drive |
|
Use Scenario: Input-stage protection for 12 V wall adapters and PoE-powered devices against AC line surges and hot-plug transients. IC Role / Device Role / Timing Role: Placed across input capacitor, clamping overvoltage before it reaches DC-DC controller ICs and MOSFETs. Use Value: 175 °C max junction temperature allows placement near heat-generating components; DO-15 footprint enables compact layout with minimal trace inductance. |
Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in smart home appliances (e.g., vacuum cleaners, blenders). IC Role / Device Role / Timing Role: Connected across motor terminals in parallel with flyback diode, absorbing energy faster than standard rectifiers. Use Value: 70 A IFSM rating accommodates repeated motor stall currents; glass passivation prevents parameter drift after thousands of surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/52 (Vishay) | Same VWM (10 V), but SMA package (DO-214AC); 400 W PPPM vs. 500 W; VF = 3.5 V at 100 A | Lower profile, surface-mount; less thermal mass - suited for space-constrained PCBs but lower surge endurance | Select SMAJ10A-E3/52 when board area is limited and surge duty cycle is light; SA10HE3/54 preferred for high-reliability through-hole mounting and full 500 W compliance. |
| P6SMB10A (Littelfuse) | Identical VWM (10 V), VBR (11.1–12.3 V), and DO-214AA package; same 500 W rating but rated for 175 °C TJ only in specific variants | Requires verification of AEC-Q101 status per batch; JEDEC DO-214AA footprint differs slightly from DO-204AC mechanical envelope | Choose P6SMB10A only if existing design uses SMB package and AEC-Q101 is not mandatory; SA10HE3/54 guarantees automotive qualification and DO-15 compatibility. |
Compared with SMAJ10A-E3/52 and P6SMB10A, SA10HE3/54 uniquely combines AEC-Q101 certification, DO-204AC through-hole robustness, and guaranteed 500 W surge handling - making it optimal for automotive and industrial applications demanding proven long-term reliability under thermal and mechanical stress.

FAQ
What is the clamping voltage of SA10HE3/54 and how is it measured?
The SA10HE3/54 has a maximum clamping voltage (VC) of 17.0 V, measured at a peak pulse current (IPPM) of 29.4 A using a 10/1000 μs waveform per IEC 61000-4-5. This value reflects the actual voltage imposed on the protected circuit during worst-case surge conditions and is specified in the Vishay datasheet Document Number 88378, page 2. The SA10HE3/54 maintains this clamping performance across its qualified temperature range.
Is SA10HE3/54 suitable for automotive applications?
Yes, SA10HE3/54 is AEC-Q101 qualified per note (1) on page 3 of the Vishay datasheet, confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. Its DO-204AC package, 175 °C max junction temperature, and HE3 suffix (JESD 201 Class 2 whisker resistance) make SA10HE3/54 appropriate for under-hood and body-control automotive modules.
What does the "HE3/54" suffix mean in SA10HE3/54?
The "HE3" suffix indicates RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while "/54" denotes the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel. This matches the ordering information example on page 3 of the Vishay datasheet, confirming SA10HE3/54 is supplied in industry-standard automated assembly format.
How does SA10HE3/54 differ from bi-directional TVS diodes like SA10CA?
SA10HE3/54 is uni-directional, with a cathode band marking and asymmetric conduction: it clamps only in reverse bias and conducts forward current up to 70 A (IFSM). In contrast, SA10CA is bi-directional, has no polarity marking, and clamps identically in both directions - making SA10HE3/54 ideal for DC power rail protection where polarity is fixed, while SA10CA suits AC or floating signal lines.
Can SA10HE3/54 replace SA10A in existing designs?
Yes - SA10HE3/54 is a direct replacement for SA10A with identical electrical specifications (VWM = 10 V, VBR = 11.1–12.3 V, VC = 17.0 V), same DO-204AC package, and enhanced reliability via AEC-Q101 qualification and HE3 whisker-resistant plating. No PCB or schematic changes are needed; SA10HE3/54 improves field reliability without altering design intent.
