Product details
Overview
P6KE10C-E3/73 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 41.4 A peak pulse current, and 600 W peak pulse power dissipation with a 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the P6KE10C-E3/73 datasheet, P6KE10C-E3/73 pinout, P6KE10C-E3/73 application, or P6KE10C-E3/73 equivalent, key selection criteria include bi-directional surge clamping capability, DO-15 package compatibility, low leakage (<10 µA at VWM), AEC-Q101 qualification status, and thermal resistance (RθJA = 75 °C/W) for board-level thermal design.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds its breakdown range (10.5–11.6 V). Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns).
Designed for repetitive 10/1000 µs surges at 0.01% duty cycle, it delivers consistent clamping performance up to 175 °C junction temperature. The bi-directional configuration eliminates polarity concerns in AC-coupled or differential signal paths such as CAN bus stubs or RS-485 lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR (Breakdown Voltage) | 10.5–11.6 V at 1 mA - Confirmed avalanche initiation range for reliable triggering |
| VC (Clamping Voltage) | 14.5 V at 41.4 A - Maximum voltage seen by protected circuit during worst-case 10/1000 µs surge |
| IPPM (Peak Pulse Current) | 41.4 A - Surge current handling capacity under standard 10/1000 µs waveform |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption without degradation |
| RθJA (Junction-to-Ambient) | 75 °C/W - Thermal resistance defining ambient temperature derating limits for PCB layout |
| TJ max. | 175 °C - Maximum allowable junction temperature for long-term reliability |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bi-directional symmetry confirmed per datasheet note.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | Either lead serves as input/output terminal; no cathode band - identical conduction in both directions |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics over temperature and lifetime |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity compliance in compact form factor |
| AEC-Q101 qualified (HE3 suffix variant) | P6KE10C-E3/73 is RoHS-compliant commercial grade; HE3 variant meets automotive stress testing requirements |
| Low incremental surge resistance | Enables tight clamping window (VC – VBR = ~3.9 V), minimizing stress on downstream ICs |
| Fast response time (<1 ns) | Clamps transients before sensitive logic or analog circuitry can be damaged |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same VWM (10 V), higher PPPM (600 W), but SMC package (larger footprint, lower RθJA = 30 °C/W) | Better thermal performance in high-density layouts; requires PCB rework for DO-15-to-SMC transition | Select SMBJ10CA when board space allows and thermal derating margin is critical |
| 1.5KE10CA | Same VWM (10 V), identical DO-15 package, but higher PPPM (1500 W) and larger junction area | Higher surge robustness for infrequent but severe events (e.g., utility grid coupling); 3× peak current rating | Choose 1.5KE10CA where IEC 61000-4-5 Level 5 or telecom GR-1089 compliance is required |
Compared with P6KE10C-E3/73, SMBJ10CA offers superior thermal management in space-tolerant designs, while 1.5KE10CA provides higher single-event surge margin at the cost of increased capacitance and slower response - making P6KE10C-E3/73 optimal for cost-sensitive, high-volume automotive and industrial applications requiring precise 14.5 V clamping control.

FAQ
What is the clamping voltage of P6KE10C-E3/73 under a 10/1000 µs surge?
The P6KE10C-E3/73 has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P6KE10C-E3/73 suitable for automotive applications?
P6KE10C-E3/73 is RoHS-compliant commercial-grade; however, the HE3-suffix variant (P6KE10CHE3/73) is AEC-Q101 qualified. For automotive use, designers must specify the HE3 version - the E3/73 variant lacks formal automotive qualification though it shares identical electrical parameters and DO-15 mechanical construction.
Does P6KE10C-E3/73 have polarity markings?
No - P6KE10C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. Per Vishay documentation, bi-directional types carry no color band or other polarity marking, confirming either lead may connect to any node in the protected circuit.
What is the thermal resistance of P6KE10C-E3/73?
The P6KE10C-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard JEDEC test conditions. This value governs power derating above 25 °C ambient and informs minimum copper pour requirements on PCBs for sustained surge duty cycles.
How does P6KE10C-E3/73 differ from P6KE10A-E3/73?
P6KE10C-E3/73 is bi-directional (denoted by 'C' suffix), while P6KE10A-E3/73 is uni-directional ('A' suffix) with a cathode band. Their VWM, VBR, and VC values are identical, but P6KE10A-E3/73 exhibits forward voltage drop (~3.5 V at 50 A) and requires correct polarity installation - unlike the polarity-agnostic P6KE10C-E3/73.
