Product details
Overview
P4KE180AHE3/54 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 180 V breakdown voltage (VBR min/max = 171–189 V), 154 V stand-off voltage (VWM), 246 V maximum clamping voltage (VC) at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE180AHE3/54 datasheet, P4KE180AHE3/54 pinout, P4KE180AHE3/54 application, or P4KE180AHE3/54 equivalent, key selection criteria include verified unidirectional polarity, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and clamping performance under 10/1000 μs surge conditions.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression in DC power rails and low-speed signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM = 154 V), while the unidirectional configuration provides cathode-marked polarity for correct orientation in series-connected protection circuits.
It delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with derating above ambient temperature per Fig. 2 and junction temperature limit of 175 °C. The 66 °C/W junction-to-lead thermal resistance supports reliable operation without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at IT = 1.0 mA - defines guaranteed avalanche onset range for design margining |
| VWM | 154 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 246 V at 1.6 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 400 W - peak transient energy absorption capability under standardized surge waveform |
| IFSM | 40 A - maximum non-repetitive forward surge current (8.3 ms half-sine), relevant for fault clearing |
| RθJL | 66 °C/W - enables thermal estimation for lead-mounted PCB layouts without heatsink |
| TJ max | +175 °C - allows operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads solderable per J-STD-002; color band denotes cathode end for unidirectional polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit; conducts during overvoltage fault in forward direction |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential rail; initiates breakdown when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable breakdown voltage and low parameter drift over lifetime and temperature |

| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3/4 surge immunity requirements in 12 V/24 V systems |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive ICs |
| UL 94 V-0 compliant molding compound | Meets flammability safety standards for enclosed industrial and automotive electronics |
Applications

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, 1000 W PPPM, lower VC = 292 V at 3.4 A, RθJA = 40 °C/W | Higher power handling but larger footprint; requires PCB re-layout | Select when higher surge immunity (IEC 61000-4-5 Level 4+) is required and space permits SMC/SMB package |
| 1.5KE180A | Same DO-41 package, 1500 W PPPM, VC = 259 V at 5.8 A, higher IFSM = 100 A | Higher clamping voltage and surge current rating; not AEC-Q101 qualified | Choose for cost-sensitive industrial applications where automotive qualification is unnecessary |
Compared with SMBJ180A and 1.5KE180A, the P4KE180AHE3/54 offers AEC-Q101 qualification and tighter thermal resistance in DO-41, making it optimal for space-constrained automotive modules requiring validated reliability - whereas alternatives trade qualification for higher power or lower cost.

FAQ
What is the breakdown voltage tolerance for P4KE180AHE3/54?
The P4KE180AHE3/54 has a specified breakdown voltage range of 171 V to 189 V at test current IT = 1.0 mA, representing ±5.6 % tolerance about the nominal 180 V rating. This tolerance is confirmed in Table 1 of Vishay document 88365 and applies to all units meeting specification limits.
Is P4KE180AHE3/54 suitable for bidirectional transient protection?
No, P4KE180AHE3/54 is a unidirectional TVS diode - its cathode is marked with a band and it conducts only in forward bias during overvoltage events. For bidirectional protection, Vishay specifies part numbers ending in "CA", such as P4KE180CA; the "A" suffix in P4KE180AHE3/54 explicitly denotes unidirectional polarity.
Does P4KE180AHE3/54 meet automotive qualification standards?
Yes, the "HE3" suffix indicates AEC-Q101 qualification per Vishay's documentation. This includes stress testing for temperature cycling, high-temperature operating life, and mechanical shock - verified for use in automotive body electronics, infotainment power supplies, and ADAS sensor interfaces.
What is the maximum clamping voltage of P4KE180AHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE180AHE3/54 is 246 V at peak pulse current IPPM = 1.6 A with a 10/1000 μs waveform, as specified in the Electrical Characteristics table of Vishay document 88365. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can P4KE180AHE3/54 be used in surface-mount designs?
No, P4KE180AHE3/54 uses the through-hole DO-41 (DO-204AL) package with axial leads and is not compatible with SMT assembly. For surface-mount equivalents, consider SMBJ180A (DO-214AA) or SMCJ180A (DO-214AB), which share similar electrical ratings but require different land patterns and reflow profiles.
