Product details
Overview
P4KE180A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 154 V stand-off voltage (VWM), 171–189 V breakdown range (VBR at 1 mA), 246 V maximum clamping voltage at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4KE180A-E3/54 datasheet, P4KE180A-E3/54 pinout, P4KE180A-E3/54 application, or P4KE180A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, thermal resistance (RθJL = 66 °C/W), AEC-Q101 qualification status, and DO-41 lead-form compatibility with manual or wave-solder assembly.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping protection device across DC rails or low-frequency signal paths. Its glass-passivated junction enables fast response (<1 ns) to ESD and surge events, while its 175 °C max junction temperature supports operation in high-ambient environments such as automotive engine control units and industrial motor drives.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity requirements when applied with appropriate series impedance. Its 1.5 W steady-state power dissipation and 66 °C/W junction-to-lead thermal resistance require attention to PCB copper area and lead length during layout to maintain reliability under repetitive transient stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for protected circuit DC bias |
| VBR min/max | 171 V / 189 V at 1 mA - guaranteed breakdown threshold range; defines minimum overvoltage level at which clamping initiates |
| VC @ IPPM | 246 V at 1.6 A - maximum clamped voltage during 10/1000 μs surge; must stay below protected device absolute maximum rating |
| PPPM | 400 W - peak pulse power handling capability; determines survivability against defined surge waveforms per IEC 61000-4-5 |
| RθJL | 66 °C/W - junction-to-lead thermal resistance; used to calculate temperature rise under sustained power dissipation or repetitive pulses |
| TJ max | +175 °C - maximum allowable junction temperature; enables use in under-hood automotive or high-temp industrial enclosures |
| IF surge | 40 A (8.3 ms half-sine) - unidirectional forward surge rating; relevant for reverse-polarity protection configurations |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and J-STD-002 solderability standard. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Reverse-biased clamping terminal | Connected to higher-potential side (e.g., VCC or signal line); blocks normal operation but avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, low-drift breakdown voltage and long-term reliability under thermal cycling and humidity exposure |
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching transients in 24 V/48 V industrial systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | DO-214AA package; 180 V VBR min/max = 180–200 V; 600 W PPPM; RθJA = 40 °C/W (surface-mount) | Higher power rating but requires SMT placement; less suitable for through-hole legacy designs or high-vibration mechanical mounting | Select SMBJ180A when board space is constrained and thermal management uses copper pour; retain P4KE180A-E3/54 for axial-leaded serviceability and wave-solder compatibility. |
| 1.5KE180A | Same DO-41 package; identical VBR and VC specs; 1500 W PPPM; higher IPPM (8.3 A); larger junction area | Designed for higher-energy surge environments (e.g., outdoor telecom cabinets); higher capacitance may affect high-speed signal integrity | Choose 1.5KE180A where IEC 61000-4-5 Level 4 compliance is mandatory; use P4KE180A-E3/54 where 400 W suffices and cost/performance balance favors standard TVS grade. |
Compared with SMBJ180A and 1.5KE180A, the P4KE180A-E3/54 offers optimal cost, proven reliability in through-hole power rails, and AEC-Q101 qualification - making it preferred for mid-tier industrial controls and automotive body electronics where 400 W surge immunity meets design requirements without over-engineering.

FAQ
What is the clamping voltage of the P4KE180A-E3/54 under a 10/1000 μs surge?
The P4KE180A-E3/54 has a maximum clamping voltage (VC) of 246 V at 1.6 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must ensure this clamping level remains below the absolute maximum ratings of downstream components like MOSFETs or ICs. The P4KE180A-E3/54 achieves this with low incremental surge resistance and a stable glass-passivated junction.
Is the P4KE180A-E3/54 suitable for automotive applications?
Yes, the P4KE180A-E3/54 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P4KE180AHE3/54), confirming its suitability for automotive body electronics, lighting control, and power distribution modules. While the E3/54 variant is commercial-grade, its 175 °C maximum junction temperature, robust DO-41 construction, and verified surge performance make it widely adopted in non-safety-critical automotive subsystems. For full qualification, confirm the HE3 suffix and review Vishay's AEC-Q101 test report for P4KE180AHE3/54.
How does the P4KE180A-E3/54 differ from the 1.5KE180A in practical design?
The P4KE180A-E3/54 and 1.5KE180A share identical voltage ratings (VBR, VWM, VC) and DO-41 packaging but differ critically in surge capacity: the 1.5KE180A delivers 1500 W PPPM vs. 400 W for the P4KE180A-E3/54. This makes the 1.5KE180A appropriate for high-energy threats like outdoor lightning surges, whereas the P4KE180A-E3/54 targets cost-sensitive, space-constrained applications where 400 W meets IEC 61000-4-5 Level 2–3 requirements. Both use the same footprint and soldering profile.
What is the thermal resistance of the P4KE180A-E3/54, and how does it affect layout?
The P4KE180A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with 10 mm lead length. This parameter governs temperature rise during repetitive surge events or sustained power dissipation. To maintain reliability, PCB layout should maximize copper area on both anode and cathode pads, keep leads ≥10 mm long if possible, and avoid thermal isolation. Exceeding 175 °C junction temperature risks parametric shift or failure - especially under >0.01% duty cycle surges.
Does the P4KE180A-E3/54 have polarity marking, and how is it oriented in circuit?
Yes, the P4KE180A-E3/54 is unidirectional and marked with a cathode band (typically black or dark stripe) on the cathode end. In circuit, the cathode connects to the higher-potential node (e.g., VCC, signal line), and the anode connects to the lower-potential reference (e.g., ground or return). This orientation allows reverse-bias clamping during overvoltage while blocking normal forward current. Incorrect polarity results in short-circuit behavior and immediate failure. Always verify band position before placement - the P4KE180A-E3/54 cannot be used bidirectionally without external circuitry.
