Product details
Overview
1.5SMC110CA-E3/57T from Vishay General Semiconductor is a bidirectional 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 min = 105 V, max = 116 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 152 V at 9.9 A, and operates across -65 °C to +150 °C junction temperature range - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC110CA-E3/57T datasheet, 1.5SMC110CA-E3/57T pinout, 1.5SMC110CA-E3/57T application, or 1.5SMC110CA-E3/57T equivalent, this page delivers verified electrical specs, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), and AEC-Q101-qualified alternatives for automotive-grade ESD and lightning transient suppression.
Technical Context
The 1.5SMC110CA-E3/57T implements an avalanche-based silicon junction structure optimized for fast response (<1 ps) to transient overvoltages. Its bidirectional symmetry enables identical clamping performance in both polarities, with VWM = 94.0 V and maximum reverse leakage ID = 1.0 µA at VWM.
It is rated for 1500 W peak pulse power under standardized 10/1000 µs waveform, derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surge duty cycle ≤ 0.01 %. The device meets J-STD-020 MSL Level 1 and is RoHS-compliant with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at IT = 1.0 mA - defines reliable avalanche initiation threshold for bidirectional clamping |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 9.9 A - clamped voltage during full 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity for lightning and inductive switching events |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8.0 mm × 8.0 mm copper pads |
| TJ Range | -65 °C to +150 °C - enables use in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount outline with 0.320" length, compatible with automated placement |
Pinout & Package
1.5SMC110CA-E3/57T uses the SMC (DO-214AB) package: molded plastic case with matte tin-plated leads, UL 94 V-0 rated, no polarity marking (bidirectional). Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per datasheet Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VBR (105–116 V), lower PPPM = 600 W, SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5 or IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤ 600 W (e.g., consumer USB ports). |
| 1.5KE110CA | Same VBR and PPPM, but axial DO-201 package - not surface-mountable, higher inductance, manual assembly only | Not compatible with automated SMT lines; introduces parasitic inductance that degrades high-speed clamping | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ110CA and 1.5KE110CA, the 1.5SMC110CA-E3/57T uniquely balances 1500 W surge capability, SMC's low-inductance SMT form factor, and automotive-grade reliability - making it optimal for production-grade automotive and industrial PCBs requiring automated assembly and high-energy immunity.

FAQ
What is the clamping voltage of the 1.5SMC110CA-E3/57T at its rated peak pulse current?
The 1.5SMC110CA-E3/57T has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 9.9 A, measured under the standard 10/1000 µs waveform. This value ensures predictable voltage limiting during surge events and is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88303. The 1.5SMC110CA-E3/57T maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is the 1.5SMC110CA-E3/57T RoHS-compliant and halogen-free?
Yes, the 1.5SMC110CA-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant and commercial-grade per Vishay's ordering nomenclature. It is not halogen-free - that designation applies to "M3" variants (e.g., 1.5SMC110CA-M3/57T). The E3 version uses standard molding compound meeting UL 94 V-0 and is qualified to JESD201 Class 2 for whisker resistance, with matte tin-plated leads solderable per J-STD-002.
Does the 1.5SMC110CA-E3/57T have AEC-Q101 qualification?
The base 1.5SMC110CA-E3/57T is not AEC-Q101 qualified; qualification requires the "HE3" or "HM3" suffix (e.g., 1.5SMC110CAHE3_A/H). Per Vishay documentation, AEC-Q101 variants are available for the 1.5SMC110CA family but must be explicitly ordered with the HE3/HM3 prefix and revision code. The 1.5SMC110CA-E3/57T remains commercial-grade with full specification compliance, including MSL Level 1 and 1500 W surge rating.
What is the thermal resistance of the 1.5SMC110CA-E3/57T, and how does it affect layout?
The 1.5SMC110CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table. To maintain safe operation at full 1500 W surge duty, PCB layout must replicate this pad area - undersized pads increase junction temperature and risk thermal runaway during repetitive transients. The 1.5SMC110CA-E3/57T does not require a heatsink but relies on adequate copper pour for thermal dissipation.
How does the bidirectional nature of the 1.5SMC110CA-E3/57T impact circuit design?
The 1.5SMC110CA-E3/57T has no polarity marking and delivers identical electrical performance in both directions - VBR, VC, and IPPM are symmetric. This eliminates orientation constraints during placement and simplifies protection of AC-coupled signals, differential buses (e.g., RS-485), or dual-supply rails. Unlike unidirectional TVS diodes, the 1.5SMC110CA-E3/57T avoids forward conduction issues on negative transients, making it ideal for telecom and sensor interfaces where voltage polarity is undefined or alternating.
