Product details
Overview
1.5KE180AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 171 V to 189 V breakdown voltage (VBR), 154 V maximum working voltage (VWM), 1500 W peak pulse power (10/1000 µs), clamping voltage of 246 V at 6.1 A, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE180AHE3_B/C datasheet, 1.5KE180AHE3_B/C pinout, 1.5KE180AHE3_B/C application, or 1.5KE180AHE3_B/C equivalent, this part delivers verified surge immunity for industrial power supplies, automotive body electronics, and telecom line cards - with AEC-Q101 qualification, RoHS compliance, and JESD 201 Class 2 whisker resistance.
Technical Context
The 1.5KE180AHE3_B/C employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental clamping resistance. Its unidirectional polarity uses a cathode band marking and supports DC-biased protection paths where reverse conduction must be blocked.
It is rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, derates linearly above 25 °C ambient per Fig. 2, and exhibits 15.4 °C/W junction-to-lead thermal resistance - enabling direct PCB trace heat sinking without external heatsinks in moderate-power applications.
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 |
|---|---|---|---|
| SMBJ180A | DO-214AA package, 1000 W PPPM, 200 V VBR min, 170 V VWM, 291 V VC @ 3.4 A | Lower power rating and higher clamping voltage; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ180A when board area is limited and surge energy is ≤1000 W; verify thermal margin due to higher RθJA. |
| 1.5KE180A-E3/54 | Same electrical specs and DO-201AD package, but commercial-grade (non-AEC-Q101), JESD 201 Class 1A whisker rating | Approved for industrial/commercial use only; not qualified for automotive or high-reliability deployments | Choose 1.5KE180A-E3/54 for cost-sensitive consumer or computing applications where AEC-Q101 is unnecessary. |
Compared with 1.5KE180AHE3_B/C, SMBJ180A offers smaller footprint but reduced surge capacity and higher clamping, while 1.5KE180A-E3/54 matches performance but lacks automotive qualification - making 1.5KE180AHE3_B/C the sole option for AEC-Q101-compliant designs requiring full 1500 W immunity.
