Product details
Overview
P6KE180-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 171 V to 189 V breakdown voltage (VBR), 154 V stand-off voltage (VWM), 246 V clamping voltage (VC) at 2.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6KE180-E3/54 datasheet, P6KE180-E3/54 pinout, P6KE180-E3/54 application, or P6KE180-E3/54 equivalent, key selection criteria include its unidirectional polarity, 1.0 mA test current, 1.0 µA max reverse leakage at VWM, -55 °C to +175 °C operating junction temperature, and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
The P6KE180-E3/54 operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs double-exponential transient waveform, with thermal derating governed by RθJL = 20 °C/W (junction-to-lead) and maximum TJ = 175 °C.
It is rated for non-repetitive peak forward surge current (IFSM) of 100 A (8.3 ms half-sine), exhibits 0.108 %/°C temperature coefficient of VBR, and maintains stable performance under repetitive 0.01 % duty cycle pulses - making it suitable for infrequent but high-energy transients like inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1.0 mA test current - defines reliable avalanche initiation threshold under DC bias |
| VWM | 154 V - maximum continuous working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 246 V at 2.4 A peak pulse current - limits downstream voltage stress during 10/1000 µs transients |
| PPPM | 600 W - peak transient energy absorption capability without failure |
| IFSM | 100 A - withstands 8.3 ms half-sine surge without bond wire fusing |
| TJ range | -55 °C to +175 °C - supports operation in under-hood automotive and industrial ambient environments |
| Package | DO-204AC (DO-15) - axial-leaded, UL 94 V-0 molded epoxy case with 0.300" lead spacing |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, glass-passivated silicon junction in flame-retardant epoxy case. Cathode indicated by color band on one end; anode is unmarked lead. Leads are matte tin-plated, solderable per J-STD-002, rated for 275 °C / 10 s solder dip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side return path | Enables unidirectional clamping - conducts only when cathode voltage exceeds anode by >VBR |
| Cathode | Current exit point in forward bias; connected to line being protected (e.g., +12 V rail) | Clamps transients to VC by shunting surge current to ground when line voltage exceeds VBR |
Key Features
| Feature | Design Value |

| 600 W peak pulse power (10/1000 µs) | Protects against high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in 12 V automotive systems |
| AEC-Q101 qualified variant available (HE3 suffix) | P6KE180HE3/54 meets stress testing for automotive electronics - not applicable to E3 commercial grade |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage margin required for downstream component safe operating area (SOA) |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Meets IPC/JEDEC standards for lead-free assembly and long-term interconnect integrity |

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; 180 V VBR min/max = 171–189 V; same VC = 246 V but lower IPPM = 2.4 A | Surface-mount footprint; requires PCB rework vs. through-hole P6KE180-E3/54 | Select SMBJ180A for space-constrained designs where automated SMT assembly is preferred. |
| 1.5KE180A | Higher 1500 W PPPM; same DO-204AC package; VBR = 171–189 V; VC = 246 V; IPPM = 6.1 A | Supports higher surge repetition rates and longer pulse durations due to greater thermal mass | Choose 1.5KE180A when protecting against repeated 10/1000 µs transients exceeding 2×/minute duty cycle. |
Compared with SMBJ180A and 1.5KE180A, the P6KE180-E3/54 offers optimal balance of cost, axial-leaded ease-of-rework, and 600 W surge handling for low-to-moderate duty-cycle protection - ideal for prototyping, industrial field service, and legacy through-hole designs.

FAQ
What is the breakdown voltage range of the P6KE180-E3/54?
The P6KE180-E3/54 has a guaranteed breakdown voltage (VBR) range of 171 V to 189 V measured at 1.0 mA test current. This range ensures consistent avalanche initiation across production lots and temperature extremes, enabling predictable clamping behavior in overvoltage protection circuits. The P6KE180-E3/54 achieves this specification using a glass-passivated silicon junction optimized for stability under thermal stress.
Is the P6KE180-E3/54 suitable for automotive applications?
The P6KE180-E3/54 is rated for commercial temperature range (-55 °C to +175 °C) and is RoHS-compliant, but it is not AEC-Q101 qualified. For automotive use, Vishay offers the P6KE180HE3/54 variant with full AEC-Q101 qualification. The P6KE180-E3/54 may be used in non-safety-critical aftermarket or industrial-adjacent automotive systems where formal qualification is not mandated.
What is the clamping voltage of the P6KE180-E3/54 at its rated peak pulse current?
The P6KE180-E3/54 clamps to a maximum of 246 V at its specified peak pulse current (IPPM) of 2.4 A under a 10/1000 µs waveform. This clamping voltage defines the upper voltage limit imposed on protected circuitry during transient events and is critical for ensuring downstream components remain within their absolute maximum ratings. The P6KE180-E3/54 achieves this with low incremental surge resistance inherent to its glass-passivated junction design.
How does the P6KE180-E3/54 differ from the 1.5KE180A?
The P6KE180-E3/54 and 1.5KE180A share identical VBR (171–189 V), VC (246 V), and DO-204AC packaging, but differ in peak pulse power: P6KE180-E3/54 is rated at 600 W, while 1.5KE180A delivers 1500 W with higher IPPM (6.1 A). The 1.5KE180A also has greater thermal mass, supporting higher surge repetition rates. The P6KE180-E3/54 remains preferred for cost-sensitive, low-duty-cycle applications where 600 W suffices.
What is the maximum reverse leakage current of the P6KE180-E3/54 at its stand-off voltage?
The P6KE180-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its stand-off voltage (VWM) of 154 V and TA = 25 °C. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. The value is confirmed per Vishay's Electrical Characteristics table and applies across the full commercial temperature range.
