Product details
Overview
P6KE15CHE3/54 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 15 V breakdown voltage (VBR min/max = 14.3–15.8 V), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed in sensor signal line protection against ESD and load-switching surges.
For engineers reviewing the P6KE15CHE3/54 datasheet, P6KE15CHE3/54 pinout, P6KE15CHE3/54 application, or P6KE15CHE3/54 equivalent, this device serves as a RoHS-compliant, DO-15 packaged TVS for bi-directional overvoltage protection in automotive ECUs, industrial I/O modules, and telecom interface circuits where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.49), and repeatable surge immunity are required.
Technical Context
The P6KE15CHE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bi-directional construction. Its 10/1000 µs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5, and it exhibits a temperature coefficient of +0.084 %/°C for VBR, enabling predictable voltage drift across -55 °C to +175 °C operating range.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting reliable operation under repetitive surge conditions when mounted on PCB copper areas ≥ 1 in². The device fails short-circuit under catastrophic overload, enabling coordination with upstream fusing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - Ensures consistent avalanche initiation across production lot; defines minimum clamping threshold under 1 mA test current. |
| VWM | 12.8 V - Maximum continuous reverse working voltage before leakage exceeds 1 µA; sets safe operating margin below breakdown. |
| VC @ IPPM | 21.2 V @ 28.3 A - Clamped voltage during 600 W transient; determines protected circuit's maximum stress level during surge event. |
| IPPM | 28.3 A - Peak pulse current capability with 10/1000 µs waveform; quantifies surge energy absorption without degradation. |

| Fast response time (<1 ns) | Clamps before sensitive downstream components experience damaging overvoltage - critical for high-speed data lines. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting 0–5 V or 4–20 mA sensor outputs (e.g., pressure, temperature) in engine control units from load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between sensor line and ground, absorbing positive/negative transients before reaching MCU ADC input. Use Value: Prevents ADC saturation and latch-up by limiting voltage to ≤21.2 V during 28.3 A surge - maintaining signal integrity and system uptime. |
Use Scenario: Shielding 16-bit analog input channels in programmable logic controllers from field-wiring induced surges and ESD. IC Role / Device Role / Timing Role: Primary front-end TVS on each channel, located adjacent to terminal block to intercept transients before signal conditioning op-amps. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) up to 1 kV/2 kA without external filtering complexity. |
| Telecom Line Interface Protection | Consumer Appliance Motor Control Board |
Use Scenario: Safeguarding RS-485 transceiver I/O pins in base station backhaul equipment exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bi-directional TVS connected line-to-ground on differential pair, leveraging symmetry to handle ± surges equally. Use Value: Maintains signal eye diagram integrity by clamping within 21.2 V while preserving <1 ns response - avoiding data corruption during surge. |
Use Scenario: Protecting microcontroller GPIOs and gate drivers on washing machine motor control boards from brush-commutator noise and relay coil kickback. IC Role / Device Role / Timing Role: Localized TVS on low-voltage control lines (e.g., Hall sensor feedback, enable signals) near MCU pins. Use Value: Eliminates need for redundant firmware error handling by preventing destructive overvoltage-induced resets or permanent I/O damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same VWM (12.8 V) and VC (24.4 V), but higher PPPM = 600 W in smaller SMB package; lower IPPM = 24.5 A. | Better suited for space-constrained PCBs; slightly higher clamping voltage reduces margin for 15 V rail protection. | Select SMBJ15CA when board area is limited and clamping voltage margin >1.6 V is acceptable. |
| 1.5KE15CA | Same DO-15 package and VBR range, but higher PPPM = 1500 W; larger die increases capacitance (≈35 pF vs. ≈15 pF). | Higher surge capacity trades off with increased junction capacitance - may degrade signal integrity on >10 MHz lines. | Choose 1.5KE15CA only for high-energy surge environments where bandwidth is not critical (e.g., AC mains input). |
Compared with SMBJ15CA and 1.5KE15CA, the P6KE15CHE3/54 delivers optimal balance of compact DO-15 footprint, AEC-Q101 qualification, low clamping ratio (1.49), and minimal parasitic capacitance - making it preferred for automotive and industrial signal-line protection where reliability, size, and speed are jointly constrained.

FAQ
What is the polarity configuration of P6KE15CHE3/54?
The P6KE15CHE3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics - neither lead is designated anode or cathode. This allows installation without orientation concern on AC-coupled or floating signal paths, and ensures identical clamping for positive and negative transients. Its CA suffix explicitly denotes bi-directionality per Vishay's naming convention.
Does P6KE15CHE3/54 meet automotive qualification standards?
Yes, the HE3 suffix in P6KE15CHE3/54 indicates AEC-Q101 qualification - verified through high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling tests. This confirms suitability for automotive applications including engine control, body electronics, and infotainment systems where extended temperature operation and long-term reliability are mandatory.
What is the maximum clamping voltage for P6KE15CHE3/54 under surge conditions?
The P6KE15CHE3/54 clamps to a maximum of 21.2 V when subjected to its rated peak pulse current of 28.3 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that downstream components - such as 3.3 V or 5 V logic interfaces - remain within safe operating voltage limits during transient events.
How does the P6KE15CHE3/54 compare to uni-directional variants like P6KE15A?
Unlike the uni-directional P6KE15A (which has a cathode band and conducts only in reverse), the P6KE15CHE3/54 provides symmetrical protection for both polarities. Its VBR range (14.3–15.8 V) and VC (21.2 V) match closely, but it lacks forward voltage specification since conduction occurs identically in either direction - making it ideal for AC or bidirectional data lines.
What packaging and compliance information applies to P6KE15CHE3/54?
P6KE15CHE3/54 is supplied in DO-204AC (DO-15) package on 13" paper tape and reel (4000 pcs/reel, code 54), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. It is RoHS-compliant (per Directive 2011/65/EU) and meets JESD 201 Class 2 whisker resistance, confirmed by the HE3 suffix and Vishay documentation.
