Product details
Overview
P6KE10CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of sensitive electronics. It features 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 8.55 V stand-off voltage - enabling robust surge suppression on DC power rails and signal lines in automotive and industrial control systems.
For engineers reviewing the P6KE10CHE3/54 datasheet, P6KE10CHE3/54 pinout, P6KE10CHE3/54 application, or P6KE10CHE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, junction temperature derating above 25 °C, AEC-Q101 qualification status, and lead-free RoHS compliance with JESD 201 Class 2 whisker resistance.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 8.55 V), but triggers into low-impedance conduction when transient voltage exceeds its 9.5–10.5 V breakdown range (measured at 1 mA). Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns) to ESD and lightning-induced surges.
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting continuous 5.0 W dissipation on infinite heatsink at TL = 75 °C. The device is rated for -55 °C to +175 °C operating junction temperature and qualified to AEC-Q101 - confirming suitability for automotive under-hood and powertrain applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse working voltage before leakage exceeds 10 μA; sets upper limit for protected circuit DC bias. |
| Breakdown Voltage (VBR) | 9.5–10.5 V at 1 mA - defines precise turn-on threshold; tight 10% tolerance enables accurate overvoltage trip point design. |
| Clamping Voltage (VC) | 14.5 V at 41.4 A IPPM - maximum voltage seen by downstream circuit during worst-case 600 W transient; critical for IC survival margin. |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs waveform) - quantifies single-event surge energy handling; supports IEC 61000-4-5 Level 4 (4 kV) compliance. |
| Junction Temperature Range | -55 °C to +175 °C - validated operation across automotive under-hood extremes and industrial ambient environments. |
| AEC-Q101 Qualification | Qualified - confirms reliability for automotive electronic modules per stress test requirements including HTOL, TC, and UHAST. |

IC Role / Device Role / Timing Role: First-line shunt suppressor upstream of USB switch IC; conducts ESD current away from data lines. Use Value: Clamps HBM ESD to <15 V within nanoseconds, protecting internal USB PHY and reducing need for secondary TVS on D+/D−. |
Use Scenario: DC feed line (48 V) powering remote telecom equipment connected via outdoor copper pairs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on power input stage, coordinated with gas discharge tube (GDT) for multi-stage protection. Use Value: Absorbs fast-rising lightning-induced surges (IEC 61000-4-5) before GDT fires, reducing let-through voltage and extending GDT lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same 10 V nominal breakdown, but 400 W PPPM (vs. 600 W); SMA package (SMT) vs. DO-15 (through-hole). | Lower surge rating limits use in automotive load dump; SMT footprint requires PCB redesign. | Select when board space is constrained and surge severity is limited to IEC 61000-4-2/4-5 Level 2. |
| 1.5KE10A | Same DO-15 package and 10 V VBR, but 1500 W PPPM; higher clamping voltage (16.7 V) and larger thermal mass. | Higher VC reduces safety margin for 12 V logic; better suited for 24 V industrial systems with higher fault energy. | Choose for legacy 24 V systems where 1.5 kW surge headroom is required and 16.7 V clamping is acceptable. |
Compared with SMAJ10A and 1.5KE10A, P6KE10CHE3/54 delivers optimal balance of 600 W surge capability, 14.5 V clamping, AEC-Q101 qualification, and through-hole manufacturability - making it the preferred choice for cost-sensitive, high-reliability 12 V automotive and industrial power rail protection.

FAQ
What is the maximum clamping voltage of P6KE10CHE3/54 and under what test condition?
The maximum clamping voltage of P6KE10CHE3/54 is 14.5 V, measured at 41.4 A peak pulse current using the standard 10/1000 μs double-exponential waveform. This value represents the highest voltage the device allows to appear across protected circuitry during a worst-case transient event, directly determining whether downstream components remain within their absolute maximum ratings. Engineers must verify this clamping level against the protected IC's VMAX specification with appropriate safety margin.
Is P6KE10CHE3/54 suitable for automotive applications, and what qualification does it hold?
Yes, P6KE10CHE3/54 is explicitly AEC-Q101 qualified, as confirmed by Vishay's documentation and the HE3 suffix designation. This qualification validates its reliability for automotive electronic control units, including exposure to temperature cycling, humidity, mechanical shock, and extended operational life under harsh under-hood conditions. The device's -55 °C to +175 °C junction temperature range and JESD 201 Class 2 whisker resistance further reinforce its suitability for automotive power and sensor interface protection.
How does the P6KE10CHE3/54 differ from the P6KE10A variant?
P6KE10CHE3/54 is the AEC-Q101 qualified, RoHS-compliant version with JESD 201 Class 2 whisker resistance, while P6KE10A is the commercial-grade variant without automotive qualification. Both share identical electrical characteristics (VWM = 8.55 V, VBR = 9.5–10.5 V, VC = 14.5 V), but P6KE10CHE3/54 undergoes additional stress testing and process controls to meet automotive reliability standards - making it mandatory for Tier 1 automotive suppliers and recommended for any mission-critical industrial application.
What is the thermal resistance and power derating behavior of P6KE10CHE3/54?
P6KE10CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Its continuous power dissipation is rated at 5.0 W on an infinite heatsink at TL = 75 °C, with linear derating above 25 °C ambient - dropping to zero at 175 °C junction temperature. This derating curve (Fig. 5 in Vishay Doc. 88369) must be applied when estimating safe operating area in enclosed or high-ambient-temperature environments.
Can P6KE10CHE3/54 be used in bi-directional protection configurations?
No, P6KE10CHE3/54 is a uni-directional TVS diode, identifiable by its cathode band marking and specified breakdown only in reverse bias. For bi-directional protection (e.g., AC lines or differential signals), Vishay offers CA-suffixed variants such as P6KE10CA. Using P6KE10CHE3/54 in bi-directional applications would result in forward conduction and potential failure during positive half-cycles - always confirm polarity and suffix (A vs. CA) before layout integration.
