Product details
Overview
1.5SMC110AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 94.0 V maximum stand-off voltage (VWM), 152 V clamping voltage (VC) at 9.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1.5SMC110AHE3_A/H datasheet, 1.5SMC110AHE3_A/H pinout, 1.5SMC110AHE3_A/H application, or 1.5SMC110AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 μA leakage at 94.0 V), then rapidly avalanches to clamp transients above VBR. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package provides robust thermal dissipation (RθJA = 75 °C/W).
Rated for repetitive 10/1000 μs surges at 0.01% duty cycle, it delivers 9.9 A peak pulse current (IPPM) at 152 V clamping, with 0.107 %/°C temperature coefficient of VBR. The cathode-band marking identifies polarity, and it meets J-STD-020 MSL Level 1 (260 °C reflow peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche onset for reliable overvoltage triggering |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 9.9 A - clamping voltage limiting protected circuit stress during 10/1000 μs surge |
| PPPM | 1500 W - peak transient power handling capability under standardized surge waveform |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush tolerance |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | SMC (DO-214AB) - surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height for high-power density |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line | Enables unidirectional clamping - conducts only when cathode is > anode by ≥VBR |
| Cathode | Current exit terminal in forward bias; marked with band, connected to higher-potential rail or signal line | Defines polarity-sensitive placement - must be oriented toward supply or signal source for correct clamping action |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| 1500 W peak pulse power | Withstands high-energy lightning-induced surges (IEC 61000-4-5 Level 4) without degradation |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal stress |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot during clamping - critical for protecting 100 V-rated MOSFETs and controllers |
| MSL Level 1, 260 °C peak | Compatible with standard lead-free reflow profiles without preconditioning or baking |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VBR range but higher VC (187 V @ 3.2 A) | Limited to lower-energy surges; unsuitable for ISO 16750-2 load dump compliance | Select when board space is constrained and surge energy does not exceed 600 W |
| 1.5KE110A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 qualification or MSL Level 1 rating | Not suitable for automated SMT production or automotive under-hood use due to packaging and qualification gaps | Choose only for legacy through-hole designs or non-automotive industrial prototypes |
Compared with SMBJ110A-E3/52 and 1.5KE110A, the 1.5SMC110AHE3_A/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC package thermal performance - making it the only option qualified for volume automotive SMT production requiring full ISO 16750-2 compliance.

FAQ
What is the clamping voltage of the 1.5SMC110AHE3_A/H under a 10/1000 μs surge?
The 1.5SMC110AHE3_A/H has a maximum clamping voltage (VC) of 152 V at 9.9 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC110AHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC110AHE3_A/H qualified for automotive applications?
Yes, the 1.5SMC110AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in revision 09-Mar-2026 of datasheet 88303. It is specifically intended for automotive use cases including engine control modules, body electronics, and ADAS power supplies where reliability under thermal cycling, humidity, and surge stress is required. The 1.5SMC110AHE3_A/H meets all applicable AEC-Q101 test conditions including HTGB, HTRB, and TCT.
What is the maximum operating temperature for the 1.5SMC110AHE3_A/H?
The 1.5SMC110AHE3_A/H has a maximum junction temperature (TJ) of +150 °C, as specified in the "Maximum Ratings" table of Vishay document 88303. This allows continuous operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in Figure 2 show that power dissipation must be reduced linearly above 25 °C ambient, with RθJA = 75 °C/W defining the thermal path to ambient air on standard 8.0 mm × 8.0 mm copper pads.
How does the 1.5SMC110AHE3_A/H differ from bidirectional variants like 1.5SMC110CA?
The 1.5SMC110AHE3_A/H is unidirectional, meaning it conducts only when cathode voltage exceeds anode by ≥VBR; it features a cathode band marking and is suited for DC rail protection. In contrast, 1.5SMC110CA is bidirectional - symmetrical conduction in both polarities, no polarity marking, and intended for AC lines or differential signal pairs. Their VBR, VC, and PPPM values differ slightly due to internal structure, and the 1.5SMC110AHE3_A/H is AEC-Q101 qualified while 1.5SMC110CA may carry different qualification codes.
What is the reverse leakage current of the 1.5SMC110AHE3_A/H at its stand-off voltage?
At the maximum stand-off voltage (VWM) of 94.0 V and ambient temperature of 25 °C, the 1.5SMC110AHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 μA, as stated in the Electrical Characteristics table of Vishay document 88303. This low leakage ensures minimal power loss and signal interference in always-on circuits such as automotive wake-up lines or sensor bias networks.
