Product details
Overview
1.5SMC110AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 1500 W peak pulse power (10/1000 μs), and clamping voltage of 152 V at 9.9 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against lightning-induced surges and inductive switching transients in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC110AHE3_A/I datasheet, 1.5SMC110AHE3_A/I pinout, 1.5SMC110AHE3_A/I application, or 1.5SMC110AHE3_A/I equivalent, this device delivers AEC-Q101 qualification, low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive electronics and ruggedized industrial interfaces.
Technical Context
This unidirectional TVS operates with a reverse stand-off voltage (VWM) of 94.0 V and maximum reverse leakage (ID) ≤ 1.0 μA at VWM, enabling reliable blocking during normal operation while triggering rapidly under overvoltage events. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device features a thermal resistance of RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), supporting robust thermal performance on standard 8.0 mm × 8.0 mm copper pads. It is rated for junction temperatures from –65 °C to +150 °C and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications

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 | Same VBR range (105–116 V), but SMB package (smaller footprint, lower PPPM = 600 W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5KE110A | Through-hole DO-201 package, identical electrical specs but higher RθJA (~100 °C/W) and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive production; requires wave soldering | Choose only for legacy through-hole designs or prototyping where RoHS-compliant SMT is unavailable |
Compared with SMBJ110A-E3/52 and 1.5KE110A, the 1.5SMC110AHE3_A/I uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC package compatibility with high-volume SMT assembly - making it the preferred choice for new automotive and industrial designs requiring certified reliability and robust transient immunity.

FAQ
What is the clamping voltage of the 1.5SMC110AHE3_A/I under maximum surge conditions?
The 1.5SMC110AHE3_A/I has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 9.9 A, measured using the standardized 10/1000 μs double-exponential waveform. This value ensures protected downstream components experience no more than 152 V during a full 1500 W transient event, provided the device is mounted per the recommended 8.0 mm × 8.0 mm copper pad layout specified in the Vishay datasheet.
Is the 1.5SMC110AHE3_A/I qualified for automotive use?
Yes, the 1.5SMC110AHE3_A/I carries AEC-Q101 qualification, confirmed by the "HE3" suffix and documented in Vishay's ordering information table. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and surge endurance validation specifically for automotive powertrain and chassis applications - making it suitable for deployment in ECUs, ADAS modules, and body electronics.
How does the 1.5SMC110AHE3_A/I differ from the standard 1.5SMC110A part?
The 1.5SMC110AHE3_A/I differs from the base 1.5SMC110A in three key ways: it includes the HE3 suffix indicating AEC-Q101 qualification, uses RoHS-compliant matte tin plating, and ships in 13-inch tape-and-reel format (I suffix). The core electrical parameters - VBR, VWM, VC, and PPPM - remain identical to the non-automotive variant, ensuring drop-in compatibility where qualification and packaging are required.
What is the maximum operating temperature for the 1.5SMC110AHE3_A/I?
The 1.5SMC110AHE3_A/I is rated for an operating junction temperature range of –65 °C to +150 °C. Its thermal resistance values - RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.) - allow sustained operation at +150 °C junction temperature when mounted on minimum recommended copper pads, supporting use in under-hood automotive locations and sealed industrial enclosures.
Does the 1.5SMC110AHE3_A/I have polarity marking, and how is it identified?
Yes, the 1.5SMC110AHE3_A/I is unidirectional and features a visible cathode band on the SMC (DO-214AB) package body. This band identifies the cathode terminal, which must be connected toward the line being protected (e.g., battery rail or signal line), while the anode is tied to ground or reference potential. No marking appears on bidirectional variants, but the 1.5SMC110AHE3_A/I is explicitly unidirectional per its "A" suffix and datasheet designation.
