Product details
Overview
P6KE16CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of DC power rails and signal lines. It features a 13.6V reverse standoff voltage (VRWM), 15.2V minimum breakdown voltage (VBR), 22.5V maximum clamping voltage (VC) at 27A peak pulse current, and fast response time for ESD and surge suppression in industrial power supplies and automotive electronics.
For engineers reviewing the P6KE16CA-T datasheet, P6KE16CA-T pinout, P6KE16CA-T application, or P6KE16CA-T equivalent, this page delivers verified electrical parameters, DO-15 terminal configuration, bidirectional clamping behavior, thermal derating curves, and direct alternatives with documented clamping voltage and peak pulse current differences.
Technical Context
The P6KE16CA-T is a glass-passivated, bidirectional TVS diode optimized for unidirectional and bidirectional surge protection without polarity sensitivity. Its 1.0ms 10/1000μs waveform-rated 600W peak pulse power and 27A IPP at 22.5V VC enable robust protection against IEC 61000-4-5 Level 3 surges.
It operates across –55°C to +175°C junction temperature range with 75°C/W junction-to-ambient thermal resistance and 15°C/W junction-to-lead resistance. The device exhibits ≤5.0μA max reverse leakage at VRWM and is RoHS-compliant with lead-free plating per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W @ 1.0ms 10/1000μs waveform - sustains high-energy transients without failure |
| Reverse Standoff Voltage (VRWM) | 13.6V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 15.2V min @ 1.0mA - onset of avalanche conduction under controlled test current |
| Clamping Voltage (VC) | 22.5V max @ 27A IPP - limits protected circuit voltage during surge event |
| Peak Pulse Current (IPP) | 27A @ 1.0ms waveform - maximum surge current the device safely clamps |
| Thermal Resistance (RθJA) | 75°C/W - defines ambient temperature rise per watt dissipated in PCB-mounted condition |
| Operating Temperature | –55°C to +175°C - supports under-hood automotive and industrial environments |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), 0.4g weight, 9.5mm lead length, with bidirectional marking (no cathode band). Leads are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity distinction - either terminal serves as anode or cathode depending on transient polarity |
| Lead 1 / Lead 2 | Current path terminals | Direct connection to protected line and ground; no internal biasing or control logic |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables single-device protection against IEC 61000-4-5 1kV/2Ω surge (Level 3) |
| Glass-passivated die construction | Improves long-term reliability and moisture resistance vs. epoxy-passivated alternatives |
| Bidirectional configuration | Eliminates need for polarity-aware layout; protects AC-coupled or floating signal lines |
| Fast response time (<1ps) | Clamps transients before downstream ICs experience overstress |
| RoHS-compliant lead finish | Meets global environmental compliance requirements without sacrificing solderability |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 12V DC input rail in programmable logic controller (PLC) power stage exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input and bulk capacitor, operating in parallel with system ground. Use Value: Limits transient voltage to ≤22.5V during 27A surges, preventing damage to 24V-rated DC-DC controllers and microcontrollers. |
Use Scenario: LIN bus interface in door module subjected to ISO 7637-2 Pulse 1 and Pulse 2a transients. IC Role / Device Role / Timing Role: Bidirectional shunt protector across LIN data line and chassis ground, responding within picoseconds. Use Value: Maintains signal integrity by clamping negative-going pulses to ≥–22.5V and positive-going to ≤+22.5V without forward conduction loss. |
| Telecom DC Feeder Line Protection | Smart Meter Power Input Stage |
Use Scenario: –48V DC telecom power feed line vulnerable to lightning-induced surges on outdoor copper pairs. IC Role / Device Role / Timing Role: Series-connected TVS pair (positive/negative rail) referenced to common ground, handling bidirectional energy. Use Value: Absorbs up to 600W for 1ms without degradation, meeting Telcordia GR-1089-CORE Level 3 surge immunity. |
Use Scenario: 230VAC-derived 12V auxiliary supply in electricity meter exposed to mains-borne surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Secondary-stage clamp after bridge rectifier and bulk capacitor, protecting low-voltage regulator inputs. Use Value: Withstands repeated 27A surges while maintaining VRWM margin above 12V nominal rail, ensuring no false triggering. |
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 VRWM (13.6V) and VC (22.5V), but 600W rating in smaller SMB package; 0.055Ω typical dynamic resistance vs. 0.33Ω for P6KE16CA-T | Higher power density enables compact PCB layouts; lower dynamic resistance improves clamping precision under fast-rising transients | Select SMBJ16CA when board space is constrained and thermal management allows SMB footprint |
| 1.5KE16CA | Same DO-15 package and bidirectional function, but 1500W peak power (2.5× higher); VC = 24.4V @ 61.5A IPP | Supports higher-energy threats (e.g., automotive load dump) but requires larger trace widths and heatsinking | Choose 1.5KE16CA where legacy DO-15 compatibility is required and surge threat level exceeds 600W |
Compared with SMBJ16CA, P6KE16CA-T offers proven thermal stability in leaded through-hole mounting but lower power density; versus 1.5KE16CA, it provides tighter clamping at lower surge energy, reducing stress on downstream regulators in cost-sensitive industrial designs.

FAQ
Is P6KE16CA-T still in active production?
No, Diodes Incorporated has officially discontinued the P6KE16CA-T and marked it as obsolete per DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock with full traceability and supports transition planning to qualified alternatives like SMBJ16CA or 1.5KE16CA.
What is the difference between P6KE16A-T and P6KE16CA-T?
P6KE16A-T is unidirectional (cathode-banded), clamping only positive transients to ground, while P6KE16CA-T is bidirectional with symmetrical clamping for both polarities. Their VRWM (13.6V), VBR (15.2V min), and VC (22.5V) are identical, but bidirectional operation eliminates polarity-dependent layout constraints.
Can P6KE16CA-T be used in place of P6KE15CA-T?
Yes, with design review: P6KE16CA-T has 13.6V VRWM vs. 12.8V for P6KE15CA-T, offering higher standoff margin. Clamping voltage rises slightly (22.5V vs. 21.2V), and peak pulse current drops (27A vs. 28A). Verify that the protected circuit's absolute maximum ratings accommodate the higher VC and reduced IPP.
Does P6KE16CA-T meet AEC-Q101 qualification?
No - the P6KE16CA-T is not AEC-Q101 qualified. Diodes offers AEC-Q101-qualified alternatives (e.g., D3SB16CA) for automotive applications requiring PPAP documentation and IATF 16949 manufacturing. This part is rated for industrial and commercial use only.
