Product details
Overview
P6KE180CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 154V reverse standoff voltage (VRWM), 171V minimum breakdown voltage (VBR), 246V maximum clamping voltage (VC) at 2.4A peak pulse current (IPP), and DO-15 package with glass-passivated junction - used in industrial power supply input stages to absorb lightning-induced surges.
For engineers reviewing the P6KE180CA-T datasheet, P6KE180CA-T pinout, P6KE180CA-T application, or P6KE180CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC rails, unidirectional vs. bidirectional polarity requirements for AC-coupled or floating lines, thermal derating above +25°C ambient, and compatibility with DO-15 footprint reflow profiles.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC signals or floating differential buses without polarity constraints. Its glass-passivated die ensures stable VBR tolerance (±5% typical) and low leakage (<5µA @ VRWM) under steady-state conditions.
The device responds to transients within <1.0ns, clamping 8/20µs surge currents up to 2.4A while maintaining VC ≤ 246V. Thermal resistance from junction to ambient is 75°C/W, requiring PCB copper area management for sustained surge duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 1.0ms non-repetitive surge without failure |
| Reverse Standoff Voltage (VRWM) | 154V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 171V min @ 1mA - onset of avalanche conduction under transient stress |
| Clamping Voltage (VC) | 246V max @ 2.4A IPP - limits downstream voltage during surge event |
| Package | DO-15 - axial-leaded through-hole package with 9.5mm lead length, UL 94V-0 rated |
| Operating Temperature | –55°C to +175°C - supports industrial and under-hood automotive environments |
| RoHS Compliance | Lead-free, halogen-free, compliant with EU Directive 2011/65/EU |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body, cathode band not marked on bidirectional version (P6KE180CA-T); leads are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with cathode in bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to anode due to bidirectional structure |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Enables single-device protection of AC lines or floating differential pairs without polarity biasing |
| 600W peak pulse rating | Handles IEC 61000-4-5 Level 4 (4kV/2Ω) surges with margin when mounted on adequate copper |
| Glass-passivated junction | Ensures stable VBR over temperature and long-term reliability in humid or contaminated environments |
| Fast response time <1.0ns | Activates before sensitive downstream circuitry (e.g., microcontroller I/O, RS-485 transceivers) sustains damage |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of input filter and DC-DC converter. Use Value: Limits transient voltage to ≤246V, protecting 28V-rated input capacitors and MOSFET gate drivers from breakdown. | Use Scenario: 12V battery-supplied BCM module subjected to alternator load dump events per ISO 16750-2. IC Role / Device Role / Timing Role: Bidirectional TVS across main power rail to suppress both positive and negative spikes. Use Value: Clamps 120V load dump peaks to 246V within 1ns, preventing latch-up in CAN transceivers and microcontrollers. |
| RS-485 Data Line Surge Suppression | AC-DC Adapter Secondary-Side Protection |
Use Scenario: Protection of isolated RS-485 transceiver bus terminals in building automation systems. IC Role / Device Role / Timing Role: Differential TVS pair (two devices) across A/B lines referenced to ground. Use Value: Maintains signal integrity by clamping ESD (IEC 61000-4-2) and surge (IEC 61000-4-5) without adding capacitance (>100pF). | Use Scenario: Output-side surge suppression on 5V/12V secondary of medical-grade AC-DC adapter. IC Role / Device Role / Timing Role: Final-stage clamp before connector to meet IEC 60601-1 creepage/surge requirements. Use Value: Prevents output voltage overshoot beyond 246V during open-circuit surge testing, ensuring connected patient-monitoring equipment remains undamaged. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170CA | Same VRWM (170V) and VC (275V), but 600W rating in SMB package (surface-mount) | Requires PCB redesign for SMT footprint; lower thermal resistance (RθJA = 40°C/W) but no lead heat-sinking | Select for space-constrained designs where automated assembly and higher thermal efficiency outweigh through-hole robustness |
| P6KE180A | Unidirectional version; identical VRWM, VBR, VC, and IPP ratings | Only protects positive-polarity transients; requires external polarity control or dual placement for AC lines | Choose only when circuit topology guarantees unidirectional surge direction (e.g., regulated DC output rails) |
Compared with SMBJ170CA and P6KE180A, P6KE180CA-T provides bidirectional protection in a proven through-hole package with superior mechanical stability and lead-based heat dissipation - critical for high-reliability industrial power inputs where board flexure or vibration is present.

FAQ
What does the "C" suffix in P6KE180CA-T indicate?
The "C" denotes bidirectional construction: the device clamps transients of either polarity symmetrically across its terminals. Unlike unidirectional versions (e.g., P6KE180A), it has no cathode marking and functions identically regardless of voltage polarity - essential for protecting AC-coupled or floating signal lines.
Can P6KE180CA-T be used in place of a unidirectional TVS like P6KE180A?
Yes, but only if bidirectional clamping is required or acceptable. Substituting P6KE180CA-T for P6KE180A introduces no electrical risk, though it removes polarity dependency. However, using P6KE180A in a bidirectional application will leave one polarity unprotected - potentially causing system failure during negative transients.
What is the maximum allowable PCB pad size for DO-15 thermal performance?
For optimal steady-state power dissipation (5.0W at TL = +75°C), Diodes specifies a copper land area of 40 mm² per lead. Exceeding this improves thermal margin but must respect IPC-2221 creepage/clearance rules - especially critical at 154V VRWM where ≥2.5mm spacing is recommended between pads and adjacent traces.
Is P6KE180CA-T qualified for automotive applications per AEC-Q101?
No - P6KE180CA-T is not AEC-Q101 qualified. While Diodes offers AEC-Q101-compliant TVS devices (e.g., D3V3M1U), this part is intended for industrial and commercial use. For automotive deployment, consult Diodes' automotive-grade product line and request PPAP documentation from their AEC-certified facilities.
