Product details
Overview
P6KE24C from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a 24V nominal breakdown voltage (VBR min/max = 21.6V/26.4V), 19.4V stand-off voltage (VWM), 34.7V maximum clamping voltage at 18A peak surge current, and low dynamic impedance for fast transient suppression in automotive and industrial control circuits.
For engineers reviewing the P6KE24C datasheet, P6KE24C pinout, P6KE24C application, or P6KE24C equivalent, key selection criteria include clamping voltage margin relative to system operating voltage, 10/1000μs surge rating compliance, unidirectional polarity marking, DO-204AC package thermal derating above 25°C, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P6KE24C operates as a silicon avalanche diode with sharp reverse-breakdown characteristics, triggered when transient voltage exceeds its VBR threshold. Its unidirectional configuration provides forward conduction capability only in one direction, requiring correct cathode-band orientation during PCB placement.
It delivers 600W non-repetitive peak pulse power under standardized 10/1000μs waveform conditions, with junction temperature rated from –55°C to +175°C and thermal derating applied above TA = 25°C per manufacturer curve Fig.2. The device exhibits <1μA reverse leakage at 19.4V and a VBR temperature coefficient of 0.094%/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 19.4 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage; sets upper limit for protected circuit operating voltage. |
| VBR (min/max) | 21.6 V / 26.4 V - Breakdown occurs within this range at 1 mA test current; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 34.7 V @ 18 A - Maximum voltage seen across terminals during 10/1000μs surge; determines worst-case stress on downstream components. |
| PPK | 600 W - Peak pulse power handling per single 10/1000μs transient; validates robustness against lightning-induced or inductive-switching surges. |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; ensures minimal power loss and no false triggering in low-power systems. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in high-ambient environments like engine compartments or enclosed industrial enclosures. |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with 0.400 g mass; compatible with standard wave-soldering and manual assembly processes. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, unidirectional configuration with cathode band marking. Leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side reference terminal | Connected to ground or lowest-potential node; forms return path during clamping event. |
| Cathode (banded end) | High-side transient input terminal | Connected to protected line (e.g., 24V rail); avalanche conduction begins here when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600W 10/1000μs surge rating | Validates protection against IEC 61000-4-5 Level 4 surges (4kV line-to-earth) without degradation in single-event testing. |
| Clamping voltage ≤34.7V at 18A | Ensures protected 24V logic or sensor interfaces remain below absolute maximum ratings during transients. |
| Fast response time <1.0 ps | Enables suppression before sensitive ICs experience destructive overvoltage-critical for CAN/LIN bus and microcontroller I/O protection. |

| UL Recognized (E326243) & RoHS/halogen-free | Supports regulatory compliance in North American and EU markets without requiring additional safety certification effort. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 24V battery-supplied ECU power input subjected to load-dump and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed directly at connector entry point to shunt surge energy to chassis ground. Use Value: Limits voltage excursion to ≤34.7V, preventing damage to downstream DC-DC converters and microcontrollers rated for 36V absolute max. |
Use Scenario: 24V digital input module receiving signals from field sensors exposed to EFT bursts and inductive kickback. IC Role / Device Role / Timing Role: Front-end TVS on each isolated input channel to absorb repetitive 5kHz EFT pulses per IEC 61000-4-4. Use Value: Maintains <1μA leakage at 19.4V, avoiding false triggering of optocoupler-based level detection while clamping 4kV transients. |
| LED Driver Overvoltage Clamp | RS-485 Transceiver Line Protection |
Use Scenario: Constant-current LED driver board powered from 24V supply in streetlight or signage applications. IC Role / Device Role / Timing Role: Unidirectional TVS across input capacitor to clamp inductive switching spikes from nearby relay coils. Use Value: Withstands 600W single-event surges and operates up to +175°C junction temperature, matching LED driver thermal environment. |
Use Scenario: RS-485 transceiver (e.g., SN65HVD230) interfacing with long cable runs in factory automation networks. IC Role / Device Role / Timing Role: Differential-line TVS pair (one per A/B line) referenced to common-mode ground to suppress common-mode surges. Use Value: Low clamping voltage (34.7V) preserves receiver common-mode range while fast response prevents data corruption during 10/1000μs events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ24A | Same DO-214AC (SMA) package; 24V nominal, 38.9V clamping at 15.3A; 400W rating; slightly higher VC and lower PPK. | Surface-mount only; requires rework of layout; better suited for space-constrained PCBs where through-hole is impractical. | Select SMAJ24A when board real estate is limited and wave-solder compatibility is not required. |
| ON Semiconductor 1.5KE24C | Same DO-204AC (DO-15) package; 24V nominal, 36.0V clamping at 16.7A; 1500W rating; higher surge capacity but larger footprint and higher leakage (5μA). | Higher power handling suits infrequent but extreme surges (e.g., utility grid coupling); less ideal for thermally dense layouts due to larger thermal mass. | Select 1.5KE24C when legacy designs require drop-in replacement with higher surge margin and thermal inertia is acceptable. |
Compared with P6KE24C, SMAJ24A offers surface-mount convenience at reduced surge rating and clamping performance, while 1.5KE24C provides higher 1500W surge capacity in identical through-hole packaging but with elevated leakage and thermal mass-making P6KE24C optimal for balanced 600W protection in cost-sensitive, thermally constrained 24V automotive and industrial systems.

FAQ
What is the polarity configuration of P6KE24C?
The P6KE24C is a unidirectional TVS diode with clearly marked cathode band. It conducts in reverse bias during overvoltage events and allows forward current flow like a standard rectifier diode. This configuration makes it suitable for DC rail protection where polarity is fixed, unlike bidirectional variants such as P6KE24CA which protect AC or floating signals.
Does P6KE24C meet AEC-Q101 qualification?
The base P6KE24C is not AEC-Q101 qualified; however, the P6KE24CH variant-identical in electrical specs and DO-204AC packaging-is explicitly qualified per AEC-Q101 Rev D. Engineers designing for automotive applications must specify P6KE24CH to ensure compliance with stress-test requirements including temperature cycling, humidity bias HAST, and mechanical shock.
How does P6KE24C compare to P6KE24A in clamping performance?
P6KE24A has tighter VBR tolerance (22.8–25.2 V vs. 21.6–26.4 V for P6KE24C) and lower clamping voltage (33.2 V vs. 34.7 V at rated surge current), resulting in ~1.5 V improved protection margin. Both share identical package, power rating, and thermal specs-so P6KE24A is preferred when precise clamping is required, while P6KE24C offers broader tolerance for cost-sensitive general-purpose use.
What is the maximum allowable ambient temperature for continuous operation of P6KE24C?
P6KE24C is rated for continuous operation up to +75°C ambient when mounted on 5 × 5 mm copper pads per lead, delivering 5 W steady-state power dissipation. Above 25°C, its 600W surge capability must be derated per Fig.2 in the datasheet-e.g., at +85°C ambient, peak pulse power drops to approximately 480W, and at +125°C, it falls to ~300W.
Can P6KE24C be used in bidirectional signal line protection?
No-P6KE24C is strictly unidirectional and unsuitable for AC or differential signal lines without external circuitry. For bidirectional protection (e.g., RS-485, USB, or audio lines), the P6KE24CA variant must be used. It features symmetrical breakdown in both directions and identical clamping performance regardless of voltage polarity, eliminating the need for polarity-aware layout.
