Product details
Overview
P6KE27CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 27 V breakdown voltage (VBR min/max = 25.7–28.4 V), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage at 16.0 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE27CA-E3/54 datasheet, P6KE27CA-E3/54 pinout, P6KE27CA-E3/54 application, or P6KE27CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 μA at VWM) under standby conditions.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), while low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The device complies with AEC-Q101 for automotive-grade reliability and uses matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, with maximum junction temperature rated at +175 °C and operating range from –55 °C to +175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM, 38.9 V VC @ 15.4 A; lower RθJA (50 °C/W) but higher capacitance (~200 pF) | Better suited for board space-constrained designs; less ideal for high-frequency signal lines due to higher junction capacitance | Select SMBJ24CA when footprint reduction and improved thermal dissipation on surface-mount layout are priorities over ultra-low leakage. |
| 1.5KE27CA | DO-201AD package; same VBR range (25.7–28.4 V); 600 W rating; higher IFSM (200 A vs. 100 A) but larger axial form factor | Preferred for legacy through-hole designs requiring higher surge endurance margin and compatibility with existing DO-201AD tooling | Choose 1.5KE27CA where mechanical robustness, higher single-pulse surge margin, or backward compatibility with older DO-201AD footprints is required. |
Compared with P6KE27CA-E3/54, SMBJ24CA offers smaller SMD footprint and better thermal resistance but trades off higher capacitance and slightly lower VWM; 1.5KE27CA provides identical electrical specs in a larger, more rugged axial package with double the IFSM, making it preferable for high-reliability industrial mains interfaces.

FAQ
What does the "CA" suffix indicate in P6KE27CA-E3/54?
The "CA" suffix in P6KE27CA-E3/54 denotes a bidirectional configuration, meaning the device clamps voltage transients equally in both polarities. Unlike unidirectional variants (e.g., P6KE27A), P6KE27CA-E3/54 has no cathode marking and functions identically regardless of terminal orientation - essential for protecting AC-coupled or floating signal paths where polarity is undefined.
Is P6KE27CA-E3/54 qualified for automotive applications?
Yes, P6KE27CA-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating P6KE27CA-E3/54 for use in engine control units, body control modules, and ADAS sensor interfaces where reliability under harsh environmental conditions is mandatory.
What is the maximum clamping voltage of P6KE27CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE27CA-E3/54 is 37.5 V at 16.0 A peak pulse current with a 10/1000 μs waveform. This value represents the upper voltage limit imposed on protected circuitry during worst-case transient events, ensuring downstream components such as 3.3 V or 5 V logic ICs remain within safe operating margins when P6KE27CA-E3/54 is correctly applied.
How does the DO-15 package of P6KE27CA-E3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE27CA-E3/54 delivers RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling effective heat transfer to PCB copper pads or chassis mounts. Its axial lead geometry supports manual or wave soldering, and the molded epoxy body meets UL 94 V-0 - making P6KE27CA-E3/54 suitable for thermally demanding environments up to +175 °C junction temperature.
Can P6KE27CA-E3/54 replace unidirectional TVS diodes in existing designs?
No - P6KE27CA-E3/54 cannot directly replace unidirectional TVS diodes (e.g., P6KE27A) without circuit review, because its symmetrical structure lacks polarity and conducts in both directions. Using P6KE27CA-E3/54 in place of a unidirectional part may cause unintended forward conduction in DC-biased lines. Replacement is only valid where bidirectional clamping is explicitly required and system topology supports non-polarized protection.
