Product details
Overview
1.5SMC110CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power with 10/1000 μs waveform, 94.0 V standoff voltage (VWM), and 152 V maximum clamping voltage (VC) at 9.9 A peak pulse current - deployed for ESD and surge protection on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the 1.5SMC110CAHE3/57T datasheet, 1.5SMC110CAHE3/57T pinout, 1.5SMC110CAHE3/57T application, or 1.5SMC110CAHE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), clamping performance under transient stress, and RoHS-compliant packaging details for robust design-in decisions.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) of 105–116 V at 1 mA test current and reverse leakage current ≤1.0 μA at 94.0 V standoff. Its glass-passivated junction enables fast response time (<1.0 ns) and low incremental surge resistance, critical for suppressing lightning-induced transients and inductive switching spikes.
Designed for automotive-grade reliability, the 1.5SMC110CAHE3/57T meets AEC-Q101 qualification, supports operating junction temperatures from –65 °C to +150 °C, and is rated for repetitive 0.01% duty cycle pulses - enabling use in harsh environments where sustained surge immunity and long-term stability are required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Lower PPPM (600 W), same VWM (94 V), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for space-constrained consumer PCBs but not for automotive under-hood surge requirements | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2. |
| 1.5KE110CA | Same VWM/VC specs, axial-leaded DO-201 package, higher RθJA (100 °C/W), no AEC-Q101 qualification | Used in legacy industrial power supplies; incompatible with automated SMT assembly | Choose only for through-hole prototyping or repair where reflow compatibility is not required. |
Compared with SMBJ110CA and 1.5KE110CA, the 1.5SMC110CAHE3/57T uniquely combines 1500 W surge capacity, AEC-Q101 qualification, SMC surface-mount compatibility, and MSL Level 1 handling - making it the preferred choice for production automotive and industrial SMT designs requiring validated reliability and high-energy clamping.

FAQ
What is the clamping voltage of the 1.5SMC110CAHE3/57T at its rated peak pulse current?
The 1.5SMC110CAHE3/57T has a maximum clamping voltage (VC) of 152 V at 9.9 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC110CAHE3/57T qualified for automotive applications?
Yes, the 1.5SMC110CAHE3/57T carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and ESD per JESD22-A114, making it suitable for automotive powertrain, chassis, and ADAS systems where reliability under thermal and electrical stress is essential.
What does the "CA" suffix mean in 1.5SMC110CAHE3/57T?
The "CA" suffix in 1.5SMC110CAHE3/57T denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., 1.5SMC110A), the CA version has no cathode band marking and functions identically regardless of voltage polarity, ideal for AC signal lines and differential interfaces.
What is the thermal resistance of the 1.5SMC110CAHE3/57T, and how does it affect PCB layout?
The 1.5SMC110CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pad per terminal. This value assumes optimal thermal land pattern; reducing pad size increases RθJA and risks thermal runaway during repetitive surges - so adherence to Vishay's layout guidelines is mandatory for rated power handling.
How does the 1.5SMC110CAHE3/57T differ from the unidirectional 1.5SMC110AHE3/57T?
The 1.5SMC110CAHE3/57T is bidirectional with symmetrical VBR (105–116 V) and clamping in both directions, while the 1.5SMC110AHE3/57T is unidirectional with cathode marking and conducts only in reverse bias. The CA variant eliminates polarity-sensitive placement and supports AC-coupled protection schemes - a key distinction for differential bus and sensor output protection.
