Product details
Overview
SA110AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for circuit protection against ESD and surge transients. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 μs), 2.8 A peak pulse current (IPPM), and clamps to ≤177 V at rated surge. Used in automotive power line and industrial sensor interface protection.
For engineers reviewing the SA110AHE3/54 datasheet, SA110AHE3/54 pinout, SA110AHE3/54 application, or SA110AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, DO-15 mechanical compatibility, 175 °C max junction temperature, and 3.0 W steady-state power dissipation under heatsink conditions.
Technical Context
The SA110AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages. Its unidirectional configuration provides cathode-anode conduction only during reverse-biased surges, with forward voltage limited to 3.5 V at 100 A.
It complies with AEC-Q101 stress testing for automotive reliability and supports repetitive surge duty cycles up to 0.01 % at 500 W. Thermal derating follows a linear curve above 25 °C ambient, maintaining safe operation up to TJ = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 122 V / 135 V at 1 mA - Confirmed avalanche onset range for reliable overvoltage triggering |
| VC @ IPPM | ≤177 V at 2.8 A - Clamped voltage during full-rated 10/1000 μs surge, limiting downstream stress |
| PPPM | 500 W - Peak transient energy absorption capability per single 10/1000 μs waveform |
| IFSM | 70 A - Non-repetitive forward surge rating (10 ms half-sine), critical for inrush tolerance |
| TJ max | +175 °C - Maximum junction temperature enabling use in under-hood or high-ambient industrial environments |
| ID @ VWM | 1.0 μA - Low leakage ensures minimal standby power loss in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/5A | Same VWM (110 V), same DO-214AC package, but lower PPPM (400 W) and higher VC (187 V) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 500 W headroom |
| 1.5KE110A | Higher VWM (110 V), same unidirectional DO-204AL package, but larger form factor and 1.5 kW PPPM (10/1000 μs) | Requires more PCB area; suited for higher-energy industrial mains protection | Choose when surge energy exceeds 500 W and board space allows axial-leaded package |
Compared with SMAJ110A-E3/5A and 1.5KE110A, the SA110AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 compactness, and 500 W capability-making it optimal for space-constrained automotive modules where reliability and standardized footprint are critical.

FAQ
What is the maximum clamping voltage of the SA110AHE3/54 under full-rated surge conditions?
The SA110AHE3/54 exhibits a maximum clamping voltage (VC) of 177 V when subjected to its rated peak pulse current (IPPM) of 2.8 A using the 10/1000 μs waveform. This value is measured per Figure 7 in the Vishay datasheet 88378 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. Maintaining VC below 177 V ensures compatibility with 150 V-rated downstream components.
Is the SA110AHE3/54 suitable for automotive applications?
Yes, the SA110AHE3/54 is AEC-Q101 qualified, confirming compliance with stress tests for temperature cycling, high-temperature reverse bias, and ESD robustness required in automotive electronics. Its DO-15 package, 175 °C max junction temperature, and unidirectional configuration make it appropriate for engine control units, body electronics, and infotainment power rails where ISO 7637-2 transient immunity is mandated.
What does the "HE3" suffix indicate in SA110AHE3/54?
The "HE3" suffix in SA110AHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms enhanced reliability for automotive and industrial use. The "54" indicates packaging in 13-inch paper tape and reel, with 4000 units per reel.
How does the SA110AHE3/54 differ from bidirectional TVS diodes like SA110CA?
The SA110AHE3/54 is unidirectional and functions only during reverse-biased overvoltage events, with forward conduction limited to 3.5 V at 100 A. In contrast, SA110CA is bidirectional and clamps symmetrically in both polarities-making it suitable for AC lines or differential data signals. SA110AHE3/54 is preferred for DC power rails where polarity is fixed and forward conduction must be controlled.
Can the SA110AHE3/54 replace the SA100AHE3/54 in an existing design?
Yes, the SA110AHE3/54 can replace SA100AHE3/54 if the system requires higher stand-off voltage (110 V vs. 100 V) and tighter VBR tolerance (122–135 V vs. 111–123 V), provided layout accommodates identical DO-15 footprint and thermal constraints remain within limits. Both share AEC-Q101 qualification, 500 W PPPM, and same pinout-enabling drop-in substitution where voltage margin is prioritized.
