Product details
Overview
P6KE180A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails 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 2.4 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and DO-15 package with matte tin-plated leads. It protects MOSFETs and ICs against inductive switching transients in industrial motor drives.
For engineers reviewing the P6KE180A-E3/54 datasheet, P6KE180A-E3/54 pinout, P6KE180A-E3/54 application, or P6KE180A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS(max), thermal resistance (RθJL = 20 °C/W), surge current capability (IPPM = 2.4 A), and AEC-Q101 qualification status for automotive-adjacent designs.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA leakage at 154 V, then avalanches sharply above 171 V to clamp transients within 1 ns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.108 %/°C).
It delivers 600 W peak pulse power per 10/1000 µs waveform with 0.01% duty cycle, derating linearly above 25 °C ambient - full power available up to 75 °C lead temperature. The DO-15 package supports manual or wave soldering (275 °C, 10 s max) and meets UL 94 V-0 flammability.
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 rail. |
| VBR (min/max) | 171 V / 189 V at 1 mA - tight 5% tolerance ensures predictable turn-on; critical for margining against MOSFET VDS(max). |
| VC @ IPPM | 246 V at 2.4 A - clamping voltage during 10/1000 µs surge; defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 600 W - peak transient energy handling capacity; enables protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω). |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; determines steady-state power dissipation limit (5.0 W at TL = 75 °C). |
| TJ(max) | +175 °C - maximum junction temperature; supports operation in high-ambient environments like engine control units. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suitable for under-hood applications. |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; cathode indicated by color band on body; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; completes conduction path during reverse-biased avalanche. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 150 V DC rail); absorbs surge energy by clamping to VC when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures ±5% VBR tolerance and stable long-term leakage performance across -55 °C to +175 °C. |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 combination wave surges up to 1 kV open-circuit / 500 A short-circuit without degradation. |
| 246 V clamping at 2.4 A | Provides 12% overvoltage margin below typical 270 V MOSFET VDS(max), enabling robust gate driver protection. |
| AEC-Q101 qualified | Validated for automotive electronics use including temperature cycling, highly accelerated life testing, and ESD immunity. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation prevents flame propagation in safety-critical industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | DO-214AA package; 170 V VWM; 274 V VC @ 2.2 A; same 600 W rating but higher clamping voltage. | Suitable for surface-mount designs where board space is constrained; requires rework of footprint and stencil. | Select SMBJ170A only if SMT assembly is mandatory and 28 V higher clamping voltage is acceptable for protected devices. |
| 1.5KE180A | Same DO-15 package; identical VWM/VBR/VC specs; 1.5 kW peak power (10/1000 µs) but larger physical size and 1.1 g weight. | Used where higher single-pulse energy absorption is required, e.g., utility meter surge protection with >2 kV line-to-ground threats. | Choose 1.5KE180A only when 1.5× surge margin is needed and PCB pad layout allows larger body dimensions (4.5 mm vs. 3.5 mm diameter). |
Compared with SMBJ170A and 1.5KE180A, P6KE180A-E3/54 offers optimal balance of compact DO-15 form factor, precise 154 V stand-off, and verified AEC-Q101 qualification - making it preferred for cost-sensitive, space-constrained, and automotive-qualified through-hole TVS deployments.

FAQ
What is the maximum clamping voltage of the P6KE180A-E3/54 under standard test conditions?
The P6KE180A-E3/54 has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.4 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and represents the worst-case voltage imposed on protected circuitry during a transient event. The P6KE180A-E3/54 maintains this clamping performance across its full operating temperature range of -55 °C to +175 °C.
Is the P6KE180A-E3/54 suitable for automotive applications?
Yes, the P6KE180A-E3/54 is AEC-Q101 qualified, having passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD immunity. Its DO-15 package with matte tin-plated leads and UL 94 V-0 molding compound meet automotive environmental requirements. While not intended for safety-critical airbag or braking systems, the P6KE180A-E3/54 is approved for use in body control modules, lighting drivers, and infotainment power supplies.
How does the P6KE180A-E3/54 differ from bidirectional TVS diodes like P6KE180CA?
The P6KE180A-E3/54 is unidirectional and features a cathode band for polarity identification, while P6KE180CA is bidirectional with no marking and symmetrical clamping in both directions. The P6KE180A-E3/54 provides lower forward voltage drop (5.0 V at 50 A) and is optimized for DC rail protection where polarity is fixed. In contrast, P6KE180CA suits AC-coupled signal lines or floating buses where voltage reversals occur. Their VWM and VBR values also differ due to internal construction.
What is the thermal resistance specification for the P6KE180A-E3/54, and how does it affect power handling?
The P6KE180A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling 5.0 W continuous power dissipation when lead temperature is maintained at 75 °C. This parameter directly governs safe steady-state operation: for example, at 25 °C ambient with minimal heatsinking, the device can sustain ~2.5 W continuously. The P6KE180A-E3/54 relies on PCB copper pour and lead length for heat transfer, not external heatsinks.
Can the P6KE180A-E3/54 be used in parallel to increase surge current capacity?
No, the P6KE180A-E3/54 should not be paralleled without individual current-sharing resistors, due to VBR mismatch (±5%) causing uneven current division and premature failure of the lower-breakdown unit. For higher surge ratings, Vishay recommends selecting a single higher-power device such as 1.5KE180A instead. The P6KE180A-E3/54 is characterized and tested as a standalone component; parallel operation voids AEC-Q101 qualification and violates JEDEC derating guidelines.
