Product details
Overview
P6KE47CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 44.7 V minimum and 49.4 V maximum breakdown voltage at 1 mA, 40.2 V stand-off voltage, 64.8 V maximum clamping voltage at 9.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE47CHE3/54 datasheet, P6KE47CHE3/54 pinout, P6KE47CHE3/54 application, or P6KE47CHE3/54 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and low leakage (<1 µA at 40.2 V) under normal operating conditions.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche breakdown in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, while the 10/1000 µs waveform rating reflects real-world lightning and inductive-switching transient immunity.
The P6KE47CHE3/54 is rated for -55 °C to +175 °C junction temperature, supports 100 A non-repetitive forward surge current (for uni-directional variants only - not applicable here), and exhibits 0.101 %/°C temperature coefficient of breakdown voltage - critical for precision clamping stability across wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 44.7–49.4 V at 1 mA - defines precise voltage threshold where avalanche conduction begins in either direction |
| Stand-off Voltage VWM | 40.2 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin below clamping onset |
| Clamping Voltage VC | 64.8 V at 9.3 A (10/1000 µs) - actual voltage seen by protected circuit during worst-case surge event |
| Peak Pulse Power PPPM | 600 W - energy-handling capacity for standardized transient waveforms; enables robust protection against IEC 61000-4-5 surges |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 25.4 mm minimum lead length, UL 94 V-0 compliant molding |
| Qualification | AEC-Q101 qualified (HE3 suffix) - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
| Leakage Current ID | <1 µA at 40.2 V - ensures negligible standby power loss and no signal distortion in high-impedance circuits |

FAQ
What does the 'HE3' suffix indicate in P6KE47CHE3/54?
The HE3 suffix in P6KE47CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification, including stress testing for temperature cycling, high-temperature reverse bias, and electrostatic discharge. This distinguishes it from the commercial-grade E3 variant and confirms suitability for automotive powertrain and chassis applications where long-term reliability under thermal and vibration stress is mandatory. The P6KE47CHE3/54 meets JESD201 Class 2 whisker resistance requirements.
Is P6KE47CHE3/54 bi-directional or uni-directional?
P6KE47CHE3/54 is explicitly bi-directional, as confirmed by the 'CA' designation in its full part number and documentation stating "devices for bi-directional applications." Unlike uni-directional P6KE47A variants, it provides symmetrical clamping in both polarities - essential for protecting AC signals, differential buses like CAN or RS-485, and floating power rails. No cathode band marking is present, consistent with bi-directional construction.
What is the maximum clamping voltage for P6KE47CHE3/54 under standard test conditions?
The maximum clamping voltage for P6KE47CHE3/54 is 64.8 V, measured at 9.3 A peak pulse current using the standardized 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during a worst-case transient event and is critical for ensuring downstream components (e.g., 75 V-rated MOSFETs or 5 V microcontrollers) remain within safe operating limits. The P6KE47CHE3/54 achieves this with a clamping ratio of approximately 1.37 relative to its VBR midpoint.
Can P6KE47CHE3/54 be used in place of P6KE47A?
No - P6KE47CHE3/54 and P6KE47A are not interchangeable due to fundamental differences: P6KE47A is uni-directional with cathode marking and forward voltage specification, while P6KE47CHE3/54 is bi-directional with no polarity marking and different leakage behavior. Substituting one for the other risks incorrect clamping behavior, especially on AC or bidirectional signal paths. Always verify circuit topology and transient polarity requirements before selecting between P6KE47A and P6KE47CHE3/54.
What packaging format is supplied for P6KE47CHE3/54?
P6KE47CHE3/54 is supplied in 13-inch diameter paper tape and reel format with a base quantity of 4000 units per reel, designated by the '/54' suffix in the ordering code. This packaging supports automated pick-and-place assembly and complies with EIA-481 standards. The device's DO-204AC (DO-15) body is compatible with standard axial-leaded insertion equipment, and lead finish meets J-STD-002 solderability requirements for both wave and reflow processes.
