Product details
Overview
P6KE15CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 15 V breakdown voltage (VBR = 14.3–15.8 V at 1 mA), 12.8 V maximum stand-off voltage (VWM), 21.2 V clamping voltage (VC) at 28.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU power inputs, industrial sensor interfaces, and USB port surge protection.
For engineers reviewing the P6KE15CHE3/73 datasheet, P6KE15CHE3/73 pinout, P6KE15CHE3/73 application, or P6KE15CHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility with through-hole PCB layouts, low 0.084 %/°C temperature coefficient of VBR, and verified clamping performance under repetitive 0.01 % duty cycle transients.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (12.8 V), it transitions from high-impedance blocking to low-impedance conduction within <1 ps, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable breakdown behavior across temperature.
Designed for unidirectional DC protection only, P6KE15CHE3/73 exhibits 3.5 V forward voltage at 50 A (per spec note 3), supports 100 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation from –55 °C to +175 °C junction temperature - enabling use in under-hood automotive environments and industrial motor drives where thermal derating must be modeled using RθJL = 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1 mA - defines precise turn-on threshold for reliable overvoltage detection without false triggering |
| VWM | 12.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 21.2 V at 28.3 A - clamping voltage limiting stress on protected ICs during 10/1000 µs surge events |
| PPPM | 600 W - peak transient power handling capability under standardized 10/1000 µs waveform |
| TJ max. | +175 °C - enables placement near heat sources (e.g., power MOSFETs) without thermal shutdown |

IC Role / Device Role / Timing Role: Primary shunt clamp placed upstream of LDO regulator and microcontroller power pins. Use Value: Limits rail voltage to ≤21.2 V during 28.3 A transients, preventing latch-up or oxide rupture in 3.3 V/5 V logic. |

| USB 2.0 VBUS Line Protection | DC Motor Drive Gate Driver Supply Protection |
|
Use Scenario: VBUS line in embedded host port encountering hot-plug inrush and ESD events per IEC 61000-4-2 Level 4. IC Role / Device Role / Timing Role: Standoff-mode TVS placed between VBUS and GND, sized to avoid crowbarring during normal 5.25 V operation. Use Value: Withstands 15 kV air/8 kV contact ESD with <21.2 V clamping, protecting USB PHY transceivers without affecting enumeration timing. |
Use Scenario: 15 V gate driver supply rail in BLDC inverter subject to shoot-through-induced voltage spikes during MOSFET switching. IC Role / Device Role / Timing Role: Fast-response shunt device absorbing sub-microsecond dv/dt spikes before gate oxide failure occurs. Use Value: Responds in <1 ps to limit transient excursions to ≤21.2 V, preserving gate driver IC integrity during 100 ns edge transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VBR range (14.3–15.8 V), but SMC package (surface-mount); lower RθJA (50 °C/W vs. 75 °C/W), higher IPPM (33.3 A) | Requires PCB rework for SMT layout; better suited for space-constrained consumer electronics vs. legacy through-hole designs | Select SMBJ15A when board real estate is limited and thermal management via copper pour is feasible |
| 1.5KE15A | Same DO-204AC package and VBR, but 1.5 kW rating (vs. 600 W); larger die, higher IPPM (100 A), higher VC (23.2 V) | Over-spec'd for most 12 V systems; may compromise clamping precision where low VC is critical (e.g., 3.3 V logic rails) | Choose 1.5KE15A only when system-level testing confirms need for >600 W surge margin and higher VC is acceptable |
Compared with SMBJ15A and 1.5KE15A, P6KE15CHE3/73 offers optimal balance of AEC-Q101 compliance, proven DO-15 mechanical robustness, and tight 21.2 V clamping - making it preferred for cost-sensitive, thermally stable, through-hole automotive and industrial control applications where exact 600 W surge handling suffices.

FAQ
What is the clamping voltage of P6KE15CHE3/73 and how is it measured?
The clamping voltage (VC) of P6KE15CHE3/73 is 21.2 V, measured at 28.3 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device during standardized surge testing and directly determines the stress imposed on downstream components. The P6KE15CHE3/73 achieves this clamping performance due to its low incremental surge resistance and optimized silicon junction design.
Is P6KE15CHE3/73 suitable for automotive applications?
Yes, P6KE15CHE3/73 is AEC-Q101 qualified and specifically rated for automotive use. Its construction includes glass-passivated junction, DO-204AC package with UL 94 V-0 epoxy, and operation up to +175 °C junction temperature - meeting requirements for engine control units, body electronics, and infotainment power supplies. The HE3 suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "HE3" suffix mean in P6KE15CHE3/73?
The "HE3" suffix in P6KE15CHE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions (e.g., P6KE15AE3/73), confirming enhanced reliability testing for automotive and harsh-environment applications. The "/73" denotes tape-and-reel packaging with 4000 units per reel.
How does P6KE15CHE3/73 differ from bi-directional TVS diodes like P6KE15CA?
P6KE15CHE3/73 is uni-directional and features a cathode band for polarity identification, while P6KE15CA is bi-directional with no polarity marking and symmetric breakdown in both directions. The uni-directional P6KE15CHE3/73 provides lower forward voltage (3.5 V at 50 A) and is intended for DC line protection where reverse conduction is not required. Bi-directional types are used for AC or data-line protection where voltage transients can occur with either polarity.
What is the thermal resistance of P6KE15CHE3/73 and how does it affect layout?
P6KE15CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. For reliable operation at full 600 W surge rating, PCB layout must provide adequate copper area on both leads to act as a heatsink - especially critical in high-temperature environments. Derating curves in the datasheet (Fig. 2 and Fig. 5) must be applied when ambient temperature exceeds 25 °C or duty cycle increases beyond 0.01 %.
