Product details
Overview
P6KE16CA-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 a 16 V breakdown voltage (VBR min/max = 15.2–16.8 V), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 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 P6KE16CA-E3/54 datasheet, P6KE16CA-E3/54 pinout, P6KE16CA-E3/54 application, or P6KE16CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status (not applicable to this E3 commercial-grade variant), thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 μA at VWM).
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche behavior in both directions, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.
The P6KE16CA-E3/54 exhibits a temperature coefficient of +0.086 %/°C for VBR, indicating predictable voltage drift over operating temperature (−55 °C to +175 °C). Its 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation up to 5.0 W under defined lead temperature conditions (TL = 75 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA test current - defines guaranteed avalanche initiation range for bidirectional clamping |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.5 V at 26.7 A - clamped voltage during 600 W transient, limiting downstream stress |
| IPPM | 26.7 A with 10/1000 μs waveform - peak surge current handling capacity under standard test condition |
| PPPM | 600 W - peak pulse power rating defining transient energy absorption capability |
| TJ max. | +175 °C - maximum junction temperature enabling operation in under-hood or high-ambient industrial environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either end functions identically - no directional installation required on PCB |
| Lead 1 / Lead 2 | Current path into/out of junction | Leads serve as both electrical connection and primary thermal conduction path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable breakdown voltage and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching spikes in 24 V industrial buses |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage exposure to protected ICs - e.g., keeps 3.3 V logic inputs below absolute maximum ratings |
| −55 °C to +175 °C operating range | Enables deployment in engine control units, motor drives, and outdoor telecom equipment without derating |
| RoHS-compliant (E3 suffix) | Meets global environmental compliance requirements for commercial-grade electronics manufacturing |
Applications
| Automotive Sensor Protection | Industrial PLC I/O 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 |
|---|---|---|---|
| SMBJ16CA | Same VWM (13.6 V) and VC (26.0 V), but SMC package (higher IPPM = 32.9 A, lower RθJA) | Requires PCB footprint change; better suited for higher-power 24 V systems with >30 A surge requirement | Select SMBJ16CA when board space allows larger SMC package and higher surge margin is needed. |
| 1.5KE16CA | Same DO-15 package and VBR range, but 1500 W PPPM rating (IPPM = 62.9 A) and higher VC (28.5 V) | Higher clamping voltage reduces protection margin for low-voltage ICs but handles more energy per event | Choose 1.5KE16CA only if system-level surge tests require >600 W capability and downstream devices tolerate 28.5 V clamping. |
Compared with SMBJ16CA and 1.5KE16CA, the P6KE16CA-E3/54 offers optimal balance of DO-15 footprint compatibility, 22.5 V clamping headroom for 3.3 V/5 V logic, and proven cost-performance for mid-tier industrial and automotive applications where 600 W surge immunity suffices.

FAQ
What is the clamping voltage of P6KE16CA-E3/54 at its rated peak pulse current?
The P6KE16CA-E3/54 has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured using the standard 10/1000 μs double-exponential waveform. This value ensures protected circuitry remains within safe operating limits during transient events, and it is verified per the Vishay datasheet revision dated 27-Sep-2021. The P6KE16CA-E3/54 maintains this performance across its full operating temperature range.
Is P6KE16CA-E3/54 AEC-Q101 qualified?
No, the P6KE16CA-E3/54 is not AEC-Q101 qualified. It carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, the HE3 suffix variant (e.g., P6KE16CAHE3/54) must be selected - confirmed in the Vishay ordering information table and mechanical notes. The P6KE16CA-E3/54 remains suitable for non-automotive-critical industrial and consumer applications where qualification is not mandated.
What does the "CA" suffix mean in P6KE16CA-E3/54?
The "CA" suffix in P6KE16CA-E3/54 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse directions. This eliminates polarity sensitivity during placement and enables use on AC signal lines, differential buses, or ungrounded power rails. The "CA" designation is explicitly defined in the Vishay datasheet's "Devices for Bidirectional Applications" section and applies uniformly across the P6KE family.
What is the maximum steady-state power dissipation for P6KE16CA-E3/54?
The P6KE16CA-E3/54 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C, as specified in the Vishay datasheet's "Maximum Ratings" table. This rating assumes ideal thermal conduction through the leads and is derated linearly above 25 °C ambient per the published thermal curve. Continuous DC power dissipation must remain well below this limit to avoid junction overheating.
How does P6KE16CA-E3/54 differ from unidirectional P6KE16A-E3/54?
The P6KE16CA-E3/54 is bidirectional with symmetrical VBR and VC in both directions, while the unidirectional P6KE16A-E3/54 has a marked cathode band and conducts only in reverse bias - forward conduction follows standard diode behavior. Their VBR, VWM, and VC values are identical, but the CA version lacks polarity marking and supports AC-coupled protection schemes. Both share DO-15 packaging and RoHS-compliant E3 termination.
