Product details
Overview
1.5KE180CA-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 across –55 °C to +175 °C. It protects MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE180CA-E3/54 datasheet, 1.5KE180CA-E3/54 pinout, 1.5KE180CA-E3/54 application, or 1.5KE180CA-E3/54 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, JEDEC 1.5KE package dimensions, thermal derating curves, and direct alternatives with documented VBR, VC, and IPPM differences - critical for ESD/lightning transient design validation.
Technical Context
This device implements a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) to transient overvoltages. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints, and its 1500 W peak pulse rating is validated under standardized 10/1000 µs waveform per R.E.A. definitions.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation up to TJ = 175 °C. The 1.5KE180CA-E3/54 uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V - Ensures reliable conduction onset above normal operating voltage while avoiding false triggering during transients. |
| VWM | 154 V - Maximum continuous working voltage; defines safe standoff level before clamping initiates. |
| VC @ IPPM | 246 V at 6.1 A - Clamped voltage during full 1500 W surge; determines maximum stress on downstream components. |
| IPPM | 6.1 A - Peak pulse current capability under 10/1000 µs waveform; used to size series impedance and verify margin. |
| PPPM | 1500 W - Peak pulse power handling; validates suitability for lightning-induced surges per IEC 61000-4-5 Level 4. |
| TJ range | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Leakage @ VWM | 1.0 µA - Low standby current preserves efficiency in always-on circuits and battery-backed systems. |
Pinout & Package
Package: JEDEC-standard Case Style 1.5KE - axial-leaded, molded epoxy body (UL 94 V-0), 0.375" (9.5 mm) lead length, 0.210" (5.3 mm) body diameter. RoHS-compliant matte tin plating per J-STD-002.

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 = 171–189 V, VC = 274 V @ 5.5 A, PPPM = 400 W, DO-214AC package | Lower peak power and higher clamping voltage reduce margin in high-energy lightning scenarios. | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 2. |
| ON Semiconductor 1.5SMC180CA | VBR = 171–189 V, VC = 246 V @ 6.1 A, PPPM = 1500 W, SMC (DO-214AB) surface-mount package | Same electrical specs but SMD footprint requires PCB redesign; no axial-leaded drop-in replacement. | Choose for automated assembly where through-hole mounting is not feasible and thermal pad layout supports RθJA ≤ 75 °C/W. |
Compared with 1.5KE180CA-E3/54, the SMAJ180CA offers space savings but sacrifices 65% peak power handling and increases clamping stress by 28 V; the 1.5SMC180CA matches all key electrical parameters but mandates re-layout due to SMD packaging and different thermal path characteristics.

FAQ
What is the breakdown voltage tolerance for 1.5KE180CA-E3/54?
The 1.5KE180CA-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 calculations in designs using 1.5KE180CA-E3/54.
Is 1.5KE180CA-E3/54 RoHS compliant and halogen-free?
Yes, the 1.5KE180CA-E3/54 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per IEC 61249-2-21. The device uses matte tin-plated leads and UL 94 V-0 epoxy molding compound, with no brominated flame retardants or chlorine-based additives - confirmed in Vishay's material declaration for 1.5KE180CA-E3/54.
Does 1.5KE180CA-E3/54 meet AEC-Q101 for automotive use?
No, the 1.5KE180CA-E3/54 is commercial-grade only. Per Vishay documentation, AEC-Q101 qualification applies only to variants with the "HE3" suffix (e.g., 1.5KE180CAHE3_B). The 1.5KE180CA-E3/54 lacks the required stress test reporting and lot traceability for automotive qualification, though it remains suitable for non-safety-critical industrial and telecom applications.
What is the maximum clamping voltage of 1.5KE180CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE180CA-E3/54 is 246 V, measured at its peak pulse current (IPPM) of 6.1 A under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for verifying that downstream components remain within their absolute maximum ratings when 1.5KE180CA-E3/54 is deployed.
Can 1.5KE180CA-E3/54 be used in parallel for higher surge capacity?
While 1.5KE180CA-E3/54 devices may be placed in parallel, Vishay does not recommend it without external balancing resistors due to VBR mismatch (±5%), which causes uneven current sharing and potential thermal runaway. For higher surge capacity, select a single higher-rated device such as 1.5KE200CA or consult Vishay's application note AN1001 on parallel TVS implementation for 1.5KE180CA-E3/54.
