Overview
P6KE20CHE3/54 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 a 20 V breakdown voltage (VBR min/max = 19.0–21.0 V at 1.0 mA), 17.1 V stand-off voltage (VWM), 27.7 V maximum clamping voltage (VC) at 21.7 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 P6KE20CHE3/54 datasheet, P6KE20CHE3/54 pinout, P6KE20CHE3/54 application, or P6KE20CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, bi-directional polarity, 175 °C max junction temperature, RoHS-compliant HE3 suffix, and compatibility with 13" paper tape & reel delivery (package code 54).
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both directions, enabling suppression of positive and negative transients without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, while the DO-204AC package supports lead-free soldering per J-STD-002 and withstands 275 °C for 10 s.
The P6KE20CHE3/54 delivers 27.7 V clamping at 21.7 A (10/1000 µs), with 1.0 µA max reverse leakage at VWM, and exhibits a 0.090 %/°C temperature coefficient of VBR. It is rated for non-repetitive surge duty cycles up to 0.01 % and derates linearly above 25 °C ambient per Fig. 2.

FAQ
What does the 'HE3' suffix indicate in P6KE20CHE3/54?
The HE3 suffix in P6KE20CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker-resistant matte tin plating. It confirms suitability for automotive electronics and high-reliability industrial use, distinguishing it from commercial-grade E3 variants. This specification applies directly to the P6KE20CHE3/54 device and is verified in Vishay document 88369.
Is P6KE20CHE3/54 unidirectional or bidirectional?
P6KE20CHE3/54 is a bi-directional TVS diode, as confirmed by the 'CA' designation implied in its family naming convention and explicitly stated in Vishay's documentation for P6KE20CA variants. It provides symmetrical clamping for both positive and negative transients, with no polarity marking on the DO-204AC package. This behavior is intrinsic to the P6KE20CHE3/54 design.
What is the maximum clamping voltage of P6KE20CHE3/54 and at what current is it specified?
The maximum clamping voltage of P6KE20CHE3/54 is 27.7 V, measured at 21.7 A peak pulse current using the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table of Vishay document 88369 and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The P6KE20CHE3/54 maintains this performance across its qualified operating temperature range.
Can P6KE20CHE3/54 be used in place of P6KE20A?
No - P6KE20CHE3/54 is bi-directional (functionally equivalent to P6KE20CA), whereas P6KE20A is unidirectional with cathode marking. Their VBR, VWM, and VC values differ slightly due to polarity architecture, and substitution would compromise protection on AC-coupled or floating lines. The P6KE20CHE3/54 must be applied only where bi-directional clamping is required.
What packaging format is supplied for P6KE20CHE3/54?
P6KE20CHE3/54 is supplied in 13-inch diameter paper tape and reel format, with 4000 units per reel (package code 54). This configuration supports automated through-hole insertion and is documented in Vishay's Ordering Information section (document 88369, page 3). The reel packaging ensures consistent orientation and mechanical protection for the DO-204AC leads during handling and placement of the P6KE20CHE3/54.
