Overview
1.5SMC110AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at 1 mA), 94 V stand-off voltage (VWM), and clamps transients to ≤152 V at 9.9 A peak pulse current (10/1000 µs), delivering 1500 W peak pulse power. It is AEC-Q101 qualified and used in automotive power supply rail protection.
For engineers reviewing the 1.5SMC110AHE3/57T datasheet, 1.5SMC110AHE3/57T pinout, 1.5SMC110AHE3/57T application, or 1.5SMC110AHE3/57T equivalent, this page provides verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data, and validated alternative parts for design-in and BOM continuity planning.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated junction and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients. Its 1500 W peak pulse power rating is specified per 10/1000 µs waveform at TA = 25 °C with 0.01% duty cycle.
Thermal performance is defined by RθJA = 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-leads). It supports operating junction temperatures from –65 °C to +150 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 | Lower peak power (600 W), same VBR range (105–116 V), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Suitable for space-constrained consumer designs with lower surge exposure; not rated for automotive load dump | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5KE110A | Through-hole DO-201 package, identical electrical specs (VBR, VC, PPPM), but no AEC-Q101 qualification or MSL-1 rating | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is preferred | Choose only for non-automotive, non-SMT applications requiring identical clamping performance without qualification overhead |
Compared with 1.5SMC110AHE3/57T, SMBJ110A-E3/52 trades 60% lower surge capacity for 30% smaller footprint and higher thermal resistance, while 1.5KE110A retains full electrical equivalence but lacks automotive qualification and surface-mount compatibility - making 1.5SMC110AHE3/57T the sole choice for AEC-Q101-compliant SMT designs demanding 1500 W clamping.

FAQ
What is the clamping voltage of the 1.5SMC110AHE3/57T under a 10/1000 µs surge?
The 1.5SMC110AHE3/57T clamps to a maximum of 152 V when subjected to its rated peak pulse current of 9.9 A (10/1000 µs waveform). This value is measured at TA = 25 °C on standard 8.0 mm × 8.0 mm copper pads and represents the upper limit of voltage seen by downstream circuitry during surge events - a critical parameter for ensuring protected ICs remain within their absolute maximum ratings. The 1.5SMC110AHE3/57T maintains this clamping performance across its qualified temperature range.
Is the 1.5SMC110AHE3/57T AEC-Q101 qualified?
Yes, the 1.5SMC110AHE3/57T is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation (Document Number 88303, Revision 09-Mar-2026). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and surge endurance - validating its suitability for automotive powertrain, chassis, and body electronics applications. The 1.5SMC110AHE3/57T is not a commercial-grade variant; it is manufactured and tested to automotive reliability standards.
What does the "HE3/57T" suffix mean in 1.5SMC110AHE3/57T?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "57T" specifies packaging: 7-inch diameter plastic tape-and-reel with 850 units per reel. This format ensures compatibility with high-speed SMT pick-and-place equipment and supports automated manufacturing. The 1.5SMC110AHE3/57T is not supplied in bulk, cut tape, or tray - only in this standardized reel configuration for production-line use.
Can the 1.5SMC110AHE3/57T be used in bidirectional configurations?
No, the 1.5SMC110AHE3/57T is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Its electrical characteristics - including breakdown voltage, clamping, and leakage - are specified only for reverse-bias operation (cathode positive relative to anode). For bidirectional protection, Vishay offers the 1.5SMC110CA variant, which has symmetrical characteristics in both polarities and no polarity marking. Using 1.5SMC110AHE3/57T in bidirectional roles risks failure during positive-going transients.
What is the thermal resistance of the 1.5SMC110AHE3/57T, and how does it affect layout?
The 1.5SMC110AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes no additional heatsinking; reducing pad size or omitting thermal vias increases RθJA, accelerating junction temperature rise during repetitive surges. To maintain reliability, PCB layout must replicate Vishay's specified pad geometry and use internal copper planes or thermal vias if operating near PPPM limits. The 1.5SMC110AHE3/57T's RθJL of 15 °C/W further emphasizes the importance of low-impedance lead-to-plane connections.
