Product details
Overview
1.5SMC110AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power 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), and clamps transients to ≤152 V at 9.9 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial DC bus protection.
For engineers reviewing the 1.5SMC110AHM3_A/I datasheet, 1.5SMC110AHM3_A/I pinout, 1.5SMC110AHM3_A/I application, or 1.5SMC110AHM3_A/I equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, AEC-Q101 qualification status, and 1500 W peak pulse power rating with <0.1% duty cycle.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events exceeding its reverse stand-off voltage (94.0 V). Its glass-passivated junction enables fast response time (<1.0 ns) and low incremental surge resistance, ensuring robust protection against lightning-induced surges and inductive switching spikes.
The device is rated for 1500 W peak pulse power (10/1000 µs), 200 A non-repetitive forward surge current (8.3 ms half-sine), and operates across -65 °C to +150 °C junction temperature range. It meets J-STD-020 MSL Level 1 and is halogen-free, RoHS-compliant, and AEC-Q101 qualified per ordering suffix HM3_A/I.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise voltage threshold at which clamping begins |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | ≤152 V at 9.9 A - clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W - peak transient energy absorption capability with 10/1000 µs waveform |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), critical for motor drive or relay coil suppression |
| TJ max | +150 °C - enables reliable operation in under-hood automotive or high-temperature industrial environments |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal requirement |

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-E3/57T | Same VBR range (105–116 V), but SMB package (DO-214AA); 600 W PPPM, lower IPPM (5.5 A) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when board space is constrained and surge threat level is ≤1 kV/42 Ω |
| 1.5KE110A | Through-hole TO-204AE (DO-201AE); identical electrical specs but larger footprint and manual assembly requirement | Used in legacy industrial power supplies where automated SMT is unavailable or thermal mass is prioritized | Choose only if existing PCB layout lacks SMC pads or requires higher mechanical robustness in vibration-prone environments |
Compared with SMBJ110A-E3/57T and 1.5KE110A, the 1.5SMC110AHM3_A/I delivers full 1500 W surge handling in an AEC-Q101-qualified SMC package - making it the optimal choice for new automotive and high-reliability industrial designs requiring automated assembly and validated automotive stress performance.

FAQ
What is the clamping voltage of the 1.5SMC110AHM3_A/I under maximum rated surge current?
The 1.5SMC110AHM3_A/I 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 per standard test conditions defined in the Vishay datasheet (Document Number: 88303), with the device mounted on 8.0 mm × 8.0 mm copper pads. The clamping voltage directly determines the maximum stress imposed on downstream components during surge events.
Is the 1.5SMC110AHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC110AHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3_A/I suffix and documentation in Vishay's 1.5SMC Series datasheet. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation - making it approved for use in engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is critical.
What does the "HM3_A/I" suffix indicate in 1.5SMC110AHM3_A/I?
The "HM3" denotes halogen-free, RoHS-compliant construction; "A" specifies AEC-Q101 qualification for the 6.8 V to 220 V voltage range; and "I" indicates packaging in 13-inch diameter tape-and-reel (3500 units per reel). This full suffix confirms the 1.5SMC110AHM3_A/I meets automotive-grade material, reliability, and logistics requirements per Vishay's ordering nomenclature.
How does the 1.5SMC110AHM3_A/I compare to bidirectional TVS diodes like 1.5SMC110CA?
The 1.5SMC110AHM3_A/I is unidirectional and intended for DC circuits with defined polarity (e.g., 12 V supply to ground), offering lower leakage and tighter VBR tolerance. In contrast, 1.5SMC110CA is bidirectional and used in AC or differential signal paths (e.g., RS-485, CAN bus). They are not interchangeable without circuit redesign due to polarity and leakage differences - the 1.5SMC110AHM3_A/I must be oriented with cathode toward the protected line.
What thermal considerations apply when using the 1.5SMC110AHM3_A/I in high-ambient environments?
The 1.5SMC110AHM3_A/I has a maximum junction temperature of +150 °C and a thermal resistance of 75 °C/W (junction-to-ambient) when mounted per recommended 8.0 mm × 8.0 mm copper pads. At 70 °C ambient, its power dissipation must remain below 6.5 W continuous (per datasheet PD rating); for repetitive surges, derating curves in Figure 2 of Document 88303 must be applied to ensure TJ stays within limit.
