Product details
Overview
P6KE180C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 180V nominal breakdown voltage (VBR min/max: 162V–198V), 600W peak pulse power rating at 10/1000μs, clamping voltage of 258V at 2.4A peak surge current, and low dynamic impedance for effective overvoltage suppression in automotive and industrial control systems.
For engineers reviewing the P6KE180C datasheet, P6KE180C pinout, P6KE180C application, or P6KE180C equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification (H-suffix variant), 175°C junction temperature rating, and compliance with IEC 61000-4-2/4-4/4-5 ESD/EFT/surge immunity standards.
Technical Context
The P6KE180C operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior-no polarity marking required-and exhibits fast response time (<5.0ns from 0V to VBR). Its junction capacitance is not specified in the provided documentation, but typical values for P6KE-series devices at 1MHz/0V are below 100pF.
It is rated for non-repetitive 10/1000μs surge waveforms up to 600W, derates linearly above 25°C ambient per Fig.2, and supports steady-state power dissipation of 5W at 75°C with 9.5mm lead length copper pads. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ180A | Unidirectional; 180V VBR (171–189V); DO-214AC package; 400W rating | Requires polarity-aware layout; lower surge rating; smaller footprint | Select when board space is constrained and unidirectional protection suffices |
| ON Semiconductor 1.5KE180C | Bidirectional; 180V VBR (162–198V); DO-201AD package; 1500W rating | Larger DO-201AD package; higher surge capacity; same clamping voltage | Select when system-level surge threat exceeds 600W and PCB real estate permits larger body |
Compared with P6KE180C, SMAJ180A offers compactness but sacrifices surge rating and bidirectionality, while 1.5KE180C delivers triple the power handling in a larger package-making P6KE180C the optimal balance of DO-15 legacy compatibility, AEC-Q101 readiness, and 600W protection for cost-sensitive automotive and industrial designs.

FAQ
What does the 'C' suffix indicate in P6KE180C?
The 'C' suffix in P6KE180C denotes bidirectional configuration-meaning the device provides symmetrical clamping in both polarities without cathode marking. This distinguishes it from unidirectional variants like P6KE180A (which has anode/cathode polarity and a band marking). P6KE180C is functionally identical to P6KE180CA in electrical specs, and both share the same 162–198V VBR range and 258V clamping voltage.
Is P6KE180C AEC-Q101 qualified?
P6KE180C itself is not AEC-Q101 qualified; only the 'H' suffix variant-P6KE180CH-is officially AEC-Q101 certified per the ordering information table. The base P6KE180C meets all electrical and mechanical specifications of the series but lacks the extended stress testing required for automotive qualification. For automotive applications, P6KE180CH must be specified to ensure compliance.
What is the maximum clamping voltage of P6KE180C and at what current is it measured?
The maximum clamping voltage of P6KE180C is 258V, measured at a peak pulse current (IPP) of 2.4A under the standard 10/1000μs waveform. This value is guaranteed across temperature and process variation per the Electrical Specifications table and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event.
Can P6KE180C replace P6KE180A in a design?
No-P6KE180C cannot directly replace P6KE180A without layout review. P6KE180A is unidirectional (cathode-banded) with 171–189V VBR and 246V clamping, while P6KE180C is bidirectional (no band) with 162–198V VBR and 258V clamping. Substituting introduces polarity ambiguity and higher clamping, risking inadequate protection in DC-coupled circuits. Use only if the application explicitly requires bidirectional behavior.
What packaging options are available for P6KE180C?
P6KE180C is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (ordering code P6KE180C) and 1,500 units per ammo box (ordering code P6KE180CA0G). Both use pure tin-plated leads compliant with J-STD-002 solderability requirements and meet JESD201 Class 2 whisker resistance standards.
