Product details
Overview
P6KE27CA-E3/73 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 a 27 V breakdown voltage (VBR min/max = 25.7–28.4 V at 1.0 mA), 23.1 V standoff voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, 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-E3/73 datasheet, P6KE27CA-E3/73 pinout, P6KE27CA-E3/73 application, or P6KE27CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status (not applicable to this E3 suffix variant), thermal resistance (RθJA = 75 °C/W), and leakage current ≤1.0 μA at VWM.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1.0 μA leakage at 23.1 V), but switches to low-impedance conduction within picoseconds when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and repeatable clamping performance across temperature.
The P6KE27CA-E3/73 is rated for 600 W peak pulse power (10/1000 μs), supports 16.0 A peak pulse current (IPPM), and maintains clamping voltage ≤37.5 V under that stress - enabling robust protection of 24 V nominal systems against ISO 7637-2 or IEC 61000-4-5 level 3 surges. Its DO-15 package provides industry-standard lead spacing and solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines reliable turn-on threshold for transient suppression |
| VWM | 23.1 V - maximum continuous working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 37.5 V at 16.0 A - clamping voltage seen by protected circuit during 600 W surge |
| PPPM | 600 W (10/1000 μs) - peak transient energy handling capacity without failure |
| IPPM | 16.0 A - maximum non-repetitive surge current the device safely clamps |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB layout heat dissipation planning |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads. Compliant with UL 94 V-0 flammability rating and RoHS (E3 suffix). No polarity marking - bidirectional operation confirmed by CA suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | No cathode band; either lead serves as input/output - enables placement without orientation check |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads carry full IPPM (16.0 A) during clamping; require ≥0.5 mm trace width for reliability |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports protection against severe load dump and inductive switching events in 24 V systems |
| Clamping ratio VC/VBR ≈ 1.35 | Low overvoltage margin preserves safe operating area of protected MOSFETs and logic ICs |
| Response time < 1.0 ps | Fast enough to suppress ESD and fast-rising transients before damage occurs to sensitive inputs |
| Low incremental surge resistance | Minimizes VC rise under high di/dt, improving clamping predictability in real-world surge events |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

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; lower 400 W PPPM; VC = 38.9 V @ 10.3 A; RθJA = 50 °C/W | Suitable for space-constrained PCBs but requires higher board thermal mass for same power handling | Select when footprint size is prioritized over peak surge rating and thermal derating margin is acceptable |
| 1.5KE27CA | Same DO-15 package; higher 1500 W PPPM; VC = 45.4 V @ 33.0 A; VWM = 23.1 V identical | Better for high-energy transients (e.g., lightning-induced surges), but larger VC margin may compromise sensitive ICs | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and clamping voltage margin allows |
Compared with SMBJ24CA and 1.5KE27CA, the P6KE27CA-E3/73 delivers optimal balance of 600 W surge capability, 37.5 V clamping, and DO-15 legacy compatibility - making it ideal for cost-sensitive, thermally managed 24 V industrial and automotive subsystems where precise voltage limiting is critical.

FAQ
What is the polarity configuration of P6KE27CA-E3/73?
The P6KE27CA-E3/73 is a bidirectional TVS diode, indicated by the "CA" suffix. It has no polarity marking on the DO-15 package and conducts symmetrically in both directions - making it suitable for AC-coupled lines or differential signal protection where voltage transients can occur with either polarity. This eliminates orientation concerns during automated assembly.
Does P6KE27CA-E3/73 meet AEC-Q101 qualification?
No - the P6KE27CA-E3/73 carries the E3 suffix, denoting RoHS-compliant commercial grade per JESD 201 Class 1A whisker testing. AEC-Q101 qualification applies only to HE3-suffixed variants (e.g., P6KE27CAHE3/73). For automotive under-hood applications requiring AEC-Q101, the HE3 version must be specified; the E3 variant is intended for industrial and consumer use cases.
What is the maximum clamping voltage of P6KE27CA-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE27CA-E3/73 is 37.5 V, measured at its rated peak pulse current (IPPM) of 16.0 A using a 10/1000 μs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events - critical for ensuring downstream components remain within their absolute maximum ratings.
How does P6KE27CA-E3/73 compare to unidirectional P6KE27A-E3/73 in circuit implementation?
Unlike the unidirectional P6KE27A-E3/73 (which has a cathode band and conducts only in reverse bias), the P6KE27CA-E3/73 provides symmetrical clamping for both positive and negative transients. This allows single-device protection of AC signals, transformer-coupled interfaces, or floating buses - eliminating need for dual-diode configurations or polarity-aware layout routing required by unidirectional variants.
What is the thermal resistance and power derating behavior of P6KE27CA-E3/73?
P6KE27CA-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W. Its power dissipation (PD) is rated at 5.0 W on an infinite heatsink at TL = 75 °C, and derates linearly above 25 °C ambient per Figure 2 in the datasheet. At 100 °C ambient, usable PD drops to ~2.5 W - requiring careful PCB copper area allocation for sustained surge duty cycles.
