Product details
Overview
P6KE47C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy ESD and surge protection in DC power rails and signal lines. It features a 47V nominal standoff voltage, 600W peak pulse power rating at 10/1000μs, clamping voltage of 67.8V at 9.2A peak surge current, and operates across –55°C to +175°C junction temperature. It is used in automotive lighting control modules to protect CAN transceiver inputs from load-dump-induced transients.
For engineers reviewing the P6KE47C datasheet, P6KE47C pinout, P6KE47C application, or P6KE47C equivalent, key selection criteria include bidirectional clamping capability, low dynamic impedance (<1Ω typical), sub-5ns response time, and AEC-Q101 qualification status - all critical for robustness in automotive ECU front-end protection circuits.
Technical Context
The P6KE47C employs a planar passivated silicon junction optimized for fast avalanche breakdown under transient overvoltage conditions. Its bidirectional configuration enables symmetrical clamping in both polarities without external polarity management, supporting direct placement across unidirectional or differential bus lines like LIN or sensor interfaces.
It delivers 600W surge handling per the standardized 10/1000μs double-exponential waveform, with thermal derating above 25°C ambient per Fig.2 and junction temperature limited to 175°C. The device exhibits <1μA reverse leakage at 38.1V (VWM), ensuring minimal standby power loss in always-on automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 47 V - defines rated standoff level before clamping activation |
| Breakdown Voltage (VBR) | 42.3–51.7 V at 1 mA - ensures reliable turn-on within specified tolerance band |
| Standoff Voltage (VWM) | 38.1 V - maximum continuous reverse voltage without significant leakage |
| Clamping Voltage (VC) | 67.8 V at 9.2 A IPP - limits downstream voltage stress during worst-case surge |
| Peak Pulse Power (PPK) | 600 W at 10/1000μs - sustains automotive load-dump and ISO 7637-2 Pulse 5a events |
| Junction Temperature Range | –55°C to +175°C - supports under-hood deployment without derating |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with legacy through-hole assembly |

| Automotive Body Control Module | Consumer Appliance Motor Drive |
Use Scenario: Front-end protection of LIN bus transceivers exposed to battery line transients during jump-start or alternator load dump. IC Role / Device Role / Timing Role: Standoff voltage (38.1V) exceeds normal LIN operating range (0–12V), enabling transparent operation until surge exceeds threshold.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ47CA | Same DO-214AC package; 600W rating; VBR = 42.2–51.8V; slightly higher VC = 69.4V @ 9.1A | Higher clamping voltage increases risk of downstream overstress in margin-constrained 5V systems | Select when footprint compatibility with SMD layout is required and VC margin allows |
| ON Semiconductor 1.5KE47CA | DO-201AD package; 1500W rating; VBR = 42.3–51.7V; VC = 67.8V @ 22A; larger thermal mass | Higher surge capacity suits industrial 24V systems but requires larger PCB area and reflow profile adjustment | Select when system-level surge immunity must exceed ISO 7637-2 Level IV and board space permits |
Compared with SMAJ47CA and 1.5KE47CA, the P6KE47C offers optimal balance of axial DO-15 compatibility, precise 67.8V clamping, and AEC-Q101 qualification - making it preferred for cost-sensitive, space-constrained automotive modules where exact form-factor retention and qualification traceability are mandatory.

FAQ
What is the clamping voltage of P6KE47C and how is it measured?
The P6KE47C has a maximum clamping voltage (VC) of 67.8 V, measured at a peak pulse current (IPP) of 9.2 A using the standardized 10/1000 μs double-exponential waveform per ANSI/IEEE C62.35. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range.
Is P6KE47C unidirectional or bidirectional, and how does that affect PCB layout?
P6KE47C is a bidirectional TVS diode, meaning it provides symmetrical clamping in both polarities without requiring orientation-specific placement. Unlike unidirectional variants (e.g., P6KE47A), it has no cathode band marking and can be mounted in either direction across differential or floating nodes - simplifying layout and eliminating polarity-check steps during assembly.
Does P6KE47C meet AEC-Q101 qualification, and what does that entail?
P6KE47C itself is not AEC-Q101 qualified; only the P6KE47CH variant (with "H" suffix) carries this qualification. AEC-Q101 certification includes stress testing for temperature cycling, highly accelerated stress test (HAST), mechanical shock, and solder heat resistance - confirming suitability for automotive under-hood applications where reliability is mission-critical.
What is the maximum reverse leakage current for P6KE47C at its standoff voltage?
At its maximum standoff voltage (VWM) of 38.1 V and TA = 25°C, the P6KE47C exhibits a maximum reverse leakage current (ID) of 1 μA. This ultra-low leakage ensures negligible power loss in always-on circuits such as automotive body control modules and battery-backed sensor nodes.
Can P6KE47C be used in place of P6KE47A in an existing design?
No - P6KE47C and P6KE47A are functionally distinct: P6KE47C is bidirectional, while P6KE47A is unidirectional. Substituting one for the other without verifying circuit polarity and clamping symmetry may result in failed protection or forward conduction during normal operation. Always validate the P6KE47C's bidirectional behavior in the target application before replacement.
