Product details
Overview
P6KE22C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection on signal and power lines. It features a 22 V breakdown voltage (VBR = 20.9–23.1 V at IT = 1.0 mA), 30.6 V maximum clamping voltage (VC) at 19.6 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and DO-204AC (DO-15) package. It protects MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems against ESD and inductive switching transients.
For engineers reviewing the P6KE22C-E3/54 datasheet, P6KE22C-E3/54 pinout, P6KE22C-E3/54 application, or P6KE22C-E3/54 equivalent, this page delivers verified electrical parameters, bi-directional clamping behavior, thermal derating curves, RoHS-compliant packaging details, and AEC-Q101-qualified alternatives - all confirmed from Vishay's official documentation (Doc. #88369, Rev. 18-Sep-12).
Technical Context
The P6KE22C-E3/54 operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent transient suppression across temperature.
It delivers 600 W peak pulse power handling under standardized 10/1000 µs waveform conditions with 0.01% duty cycle, and exhibits fast response time (<1 ns) due to its low-junction-capacitance design. Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting reliable operation up to TJ = +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at IT = 1.0 mA - defines precise avalanche initiation threshold for bi-directional clamping |
| VWM | 18.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 30.6 V at 19.6 A - clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPPM | 600 W - peak transient energy absorption capability under standard waveform, enabling robust surge immunity |
| IPPM | 19.6 A - maximum non-repetitive surge current the device safely clamps without degradation |
| TJ max. | +175 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial use |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy housing |

|---|---|
|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across signal pair or supply rail to limit transients to safe levels before reaching sensitive front-end circuitry. Use Value: Prevents latch-up or permanent damage to microcontrollers and analog-to-digital converters during ISO 7637-2 pulse 1/2a/5a events. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff protector on 24 V DC input channels, absorbing repetitive 600 W surges without degradation over >100,000 cycles. Use Value: Extends mean time between failures (MTBF) of I/O cards by eliminating field returns caused by transient-induced firmware resets. |
| Consumer Audio Line Protection | Telecom DSL Line Interface |
|
Use Scenario: Shielding balanced audio inputs (e.g., XLR, TRS) in AV receivers and studio mixers from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance bi-directional clamp across differential pair, preserving signal integrity up to 20 kHz while suppressing ±8 kV HBM ESD. Use Value: Maintains THD+N < 0.005% at 1 kHz while meeting IEC 61000-4-2 Level 4 compliance without adding insertion loss. |
Use Scenario: Front-end surge suppression on ADSL/VDSL line cards interfacing twisted-pair copper infrastructure subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary protection stage before gas discharge tube (GDT) and secondary TVS, clamping fast-rising transients before GDT fires. Use Value: Reduces let-through voltage to <35 V within 1 ns, preventing damage to line driver amplifiers rated for only 40 V absolute maximum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | Same VBR range (20.9–23.1 V), but SMC package (higher IPPM = 32.3 A, lower RθJA = 40 °C/W) | Better thermal performance and surge margin; requires PCB rework for surface-mount layout | Select when higher surge endurance (>600 W) and automated assembly are priorities over through-hole compatibility |
| P6KE22CA-E3/54 | Identical specifications and DO-204AC package; CA suffix explicitly denotes bi-directional version (P6KE22C-E3/54 is functionally identical per Vishay Doc. #88369) | No functional or mechanical difference - CA is the standardized bi-directional designation | Prefer P6KE22CA-E3/54 for procurement clarity; P6KE22C-E3/54 is a legacy/variant marking with identical datasheet specs |
Compared with SMBJ22CA and P6KE22CA-E3/54, the P6KE22C-E3/54 offers drop-in through-hole replacement capability with proven field reliability in legacy industrial designs, while trading off some surge headroom and thermal efficiency for ease of manual repair and compatibility with existing DO-15 footprints.

FAQ
What does the "C" suffix in P6KE22C-E3/54 signify?
The "C" suffix in P6KE22C-E3/54 explicitly denotes a bi-directional configuration, confirming symmetrical clamping behavior in both polarities. This matches Vishay's official designation convention where "CA" is the full bi-directional suffix (e.g., P6KE22CA), and "C" is an accepted variant marking for the same device. The P6KE22C-E3/54 shares identical VBR, VC, and IPPM values with P6KE22CA-E3/54 per Document #88369.
Is P6KE22C-E3/54 RoHS compliant and halogen-free?
Yes, P6KE22C-E3/54 is RoHS compliant (per Directive 2011/65/EU) and meets JEDEC JS709A halogen-free standards. The "E3" suffix confirms matte tin-plated leads, JESD 201 Class 1A whisker resistance, and UL 94 V-0 flammability rating of the DO-204AC epoxy body - all verified in Vishay's material declarations and packaging documentation.
What is the maximum clamping voltage of P6KE22C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE22C-E3/54 is 30.6 V at IPPM = 19.6 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range (-55 °C to +175 °C) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE22C-E3/54 be used in automotive applications?
P6KE22C-E3/54 is rated for operation up to +175 °C junction temperature and built on glass-passivated junction technology, but only the HE3-suffix variant (e.g., P6KE22CHE3/54) is officially AEC-Q101 qualified. For automotive use, specify the HE3 version to ensure validated reliability under thermal cycling, mechanical shock, and humidity testing per AEC-Q101 requirements.
How does P6KE22C-E3/54 compare to uni-directional P6KE22A-E3/54 in circuit design?
Unlike the uni-directional P6KE22A-E3/54 - which requires correct cathode orientation and conducts forward current above ~3.5 V - the P6KE22C-E3/54 provides identical clamping in both directions with no polarity marking. This eliminates risk of incorrect placement on AC-coupled or floating lines and simplifies layout for bidirectional data buses like RS-485 or CAN, where P6KE22C-E3/54 is the appropriate choice.
