Product details
Overview
P6KE47H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 47V nominal breakdown voltage (VBR min/max: 42.3V–51.7V), 38.1V stand-off voltage (VWM), clamps to ≤67.8V at 9.2A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input stages.
For engineers reviewing the P6KE47H datasheet, P6KE47H pinout, P6KE47H application, or P6KE47H equivalent, key selection criteria include its AEC-Q101 qualification, low dynamic impedance, sub-1ps response time from 0V to VBR, <1μA leakage above 10V, and compatibility with 10/1000μs surge waveforms in automotive body electronics and industrial I/O protection.
Technical Context
The P6KE47H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (42.3–51.7V at 1mA test current). Its clamping action limits transient energy to ≤67.8V at 9.2A, delivering 600W peak pulse power under standardized 10/1000μs waveform conditions.
Thermal performance is rated for junction temperatures from –55°C to +175°C, with derating applied above 25°C ambient per Fig.2. The device exhibits a temperature coefficient of VBR at 0.101%/°C and junction capacitance below 100pF at 0V bias (f = 1MHz), supporting ESD and EFT immunity in medium-speed analog and digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 38.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin for 48V systems. |
| VBR (min/max) | 42.3 V / 51.7 V - Breakdown occurs within this range at 1 mA; ensures consistent triggering across production lots. |
| VC @ IPP | 67.8 V @ 9.2 A - Clamped voltage during 10/1000μs surge; determines protected circuit's maximum stress level. |
| PPK | 600 W - Peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 4 surges. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments. |
| Response time | <1.0 ps - Time from 0 V to VBR under fast-rising transients; critical for protecting high-speed logic and microcontrollers. |
| Leakage ID | <1 μA @ VWM - Minimal standby current; preserves battery life in always-on automotive modules. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to system ground or low-side reference; carries full surge current during transient events. |
| Cathode | Reverse-biased terminal / high-voltage sensing node | Connected to protected line (e.g., 48V rail); initiates avalanche breakdown when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and body control modules. |
| 600W surge rating (10/1000μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs. |
| Clamping voltage ≤67.8V | Ensures downstream 75V-rated components (e.g., MOSFETs, regulators) remain within safe operating area. |
| Dynamic impedance < 10 Ω | Minimizes voltage overshoot during fast transients, improving protection fidelity for sensitive ICs. |
| Leakage < 1 μA above 10V | Enables use in low-power wake-up circuits without compromising quiescent current budgets. |
Applications
| Automotive Power Input Protection | Industrial PLC Analog Input Protection |

Use Value: Low dynamic impedance (<10Ω) prevents voltage overshoot beyond 5.5V tolerance of 3.3V/5V logic interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ48A | 600W rating, 48V nominal, DO-214AA package; slightly higher VWM (38.8V) and lower VC (77.4V @ 7.7A). | Surface-mount footprint; better suited for high-density PCBs but requires reflow-compatible layout. | Select SMBJ48A when board space is constrained and SMT assembly is preferred over through-hole. |
| 1.5KE47A | Same DO-204AC package and 47V rating, but 1500W peak power; larger die, higher thermal mass, and higher leakage (5μA @ VWM). | Over-specified for 600W needs; used where multi-pulse robustness or extended lifetime under repeated surges is required. | Choose 1.5KE47A only if legacy design reuse or extreme surge endurance (>1000 pulses) is mandated. |
Compared with SMBJ48A and 1.5KE47A, the P6KE47H offers optimal balance of AEC-Q101 qualification, through-hole manufacturability, and precise 600W/47V coordination-making it ideal for cost-sensitive, high-reliability automotive and industrial power entry designs.

FAQ
What is the polarity configuration of the P6KE47H?
The P6KE47H is a unidirectional TVS diode with cathode indicated by a band marking on the DO-204AC (DO-15) package. It conducts in forward bias like a standard diode and clamps in reverse bias when voltage exceeds its breakdown range (42.3–51.7V). This configuration is optimized for DC rail protection where polarity is fixed, unlike bidirectional variants such as P6KE47CA.
Does the P6KE47H meet automotive qualification standards?
Yes, the P6KE47H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming validation for automotive applications including temperature cycling, mechanical shock, and humidity testing. It is not rated for safety-critical systems (e.g., airbag controllers) but is approved for body electronics, lighting, and infotainment power rails.
How does the P6KE47H compare to the P6KE47A variant?
The P6KE47H shares identical electrical specifications with P6KE47A-including VBR (44.7–49.4V), VWM (40.2V), and VC (64.8V @ 9.7A)-but adds AEC-Q101 qualification and enhanced process controls. The "H" suffix denotes automotive-grade screening, while "A" indicates standard industrial grade without automotive test validation.
What is the maximum surge current the P6KE47H can handle?
The P6KE47H supports a maximum peak surge current (IPP) of 9.2A under the standard 10/1000μs waveform, corresponding to its 600W peak pulse power rating. At elevated ambient temperatures, this value derates per Figure 2 in the datasheet-e.g., to ~7.4A at 75°C ambient-requiring thermal design consideration in enclosed enclosures.
Can the P6KE47H be used in bidirectional signal line protection?
No, the P6KE47H is unidirectional and unsuitable for AC or bipolar signal lines. For bidirectional protection, select the P6KE47CA variant, which provides symmetrical clamping in both directions with matched VBR and VC characteristics. Using P6KE47H on AC signals risks forward conduction and failure during negative half-cycles.
