Overview
1.5KE180C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 180 V breakdown voltage (VBR = 171–189 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 246 V at 6.1 A, 1.0 µA max reverse leakage at 154 V, and operates from –55 °C to +175 °C. It protects MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE180C-E3/54 datasheet, 1.5KE180C-E3/54 pinout, 1.5KE180C-E3/54 application, or 1.5KE180C-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, bidirectional clamping behavior, thermal derating curves, and direct alternatives with documented VWM/VC/IPPM differences - all critical for ESD/lightning transient design validation.
Technical Context
This device implements an avalanche-based silicon junction structure optimized for sub-nanosecond response (<1 ns) to fast-rising transients. Its bidirectional configuration enables symmetrical clamping across both polarities without external polarity management, supporting AC-coupled lines and differential buses.
It uses glass passivated chip junction technology for stable VBR tolerance (±5 %), low incremental surge resistance, and robust surge handling up to 200 A IFSM (unidirectional only; not applicable here). The 1.5KE case meets UL 94 V-0 and JESD22-B106 solderability standards, with matte tin-plated leads compliant to J-STD-002.
Key Specifications

IC Role / Device Role / Timing Role: Bidirectional TVS installed across primary DC input (48 V) to shunt common-mode surges coupled onto twisted-pair feeds. Use Value: Limits voltage excursion to 246 V during 10/1000 µs surges, preventing damage to DC/DC converters rated for 36–57 V input range. | Use Scenario: DC-link overvoltage suppression in solar microinverters where PV string voltages reach 600 V and switching transients exceed 1000 V. IC Role / Device Role / Timing Role: Secondary-level clamping device on auxiliary control rails (e.g., 150 V bias supply) to protect gate drivers and isolation amplifiers. Use Value: Provides precise 154 V standoff with 246 V clamping, enabling tighter margin design versus generic 200 V TVS devices that would compromise noise immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ180CA | VBR = 180–200 V, VC = 291 V @ 5.1 A, PPPM = 400 W, SMA package (SMT) | Lower peak power and surface-mount form factor; suited for space-constrained PCBs but insufficient for 4 kV IEC 61000-4-5 compliance. | Select when board area is critical and surge requirements are limited to IEC 61000-4-2/4-4; avoid for mains-connected or outdoor interfaces. |
| ON Semiconductor 1.5SMC180CA | VBR = 171–189 V, VC = 246 V @ 6.1 A, PPPM = 1500 W, SMC package (SMT) | Identical electrical specs but in SMC-2 surface-mount package; lacks axial lead mechanical robustness for high-vibration environments. | Choose for automated SMT production where vibration is minimal and thermal relief via copper pour is feasible; verify RθJA derating vs. DO-201AD. |
Compared with 1.5KE180C-E3/54, SMAJ180CA offers smaller footprint but sacrifices 66 % peak power capability and fails Level 4 surge testing, while 1.5SMC180CA matches electrical performance but requires requalification of board-level thermal management and mechanical mounting reliability.

FAQ
What is the breakdown voltage tolerance for 1.5KE180C-E3/54?
The 1.5KE180C-E3/54 has a specified breakdown voltage range of 171 V to 189 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 180 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports predictable system-level surge margin analysis without overspecifying downstream components.
Is 1.5KE180C-E3/54 suitable for automotive applications?
Yes, 1.5KE180C-E3/54 is qualified to AEC-Q101 when ordered with the HE3 suffix (e.g., 1.5KE180CHE3_B), but the standard 1.5KE180C-E3/54 variant is commercial-grade. For automotive body control modules or infotainment power rails, confirm qualification status via the full part number and consult Vishay's AEC-Q101 certificate for the specific revision code.
How does the clamping voltage of 1.5KE180C-E3/54 compare to its standoff voltage?
The 1.5KE180C-E3/54 has a maximum standoff voltage (VWM) of 154 V and a maximum clamping voltage (VC) of 246 V at 6.1 A. This 92 V differential provides a defined safety margin - sufficient to protect 150 V-rated components while ensuring the device remains non-conductive during normal operation and triggers only during validated surge events.
Can 1.5KE180C-E3/54 be used in bidirectional AC circuits?
Yes, 1.5KE180C-E3/54 is explicitly designed for bidirectional applications, with identical electrical characteristics in both polarities. It is commonly deployed across AC mains inputs, transformer secondaries, and differential data lines like RS-485, where polarity-independent clamping prevents misapplication and eliminates need for orientation-aware placement.
What is the thermal resistance of 1.5KE180C-E3/54 and how does it affect power handling?
The 1.5KE180C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. At 25 °C ambient, its 6.5 W steady-state power dissipation is limited by RθJA; however, during transient events, RθJL governs short-duration energy absorption - enabling full 1500 W pulse handling when leads are soldered to adequate copper area.
