Product details
Overview
P6KE13C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4 V / 13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE13C-E3/73 datasheet, P6KE13C-E3/73 pinout, P6KE13C-E3/73 application, or P6KE13C-E3/73 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient protector for bi-directional signal lines where fast response (<1 ns), low clamping voltage, and repeatable surge immunity are required - especially in CAN bus front-end protection, RS-485 transceivers, and automotive body electronics.
Technical Context
The P6KE13C-E3/73 operates as a bi-directional avalanche diode, symmetrically clamping voltage surges in both polarities without polarity marking. Its glass-passivated junction enables stable breakdown behavior and low incremental surge resistance, critical for consistent clamping under repetitive 10/1000 μs transients at ≤0.01% duty cycle.
It delivers 18.2 V clamping at 33.0 A IPPM, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting operation from –55 °C to +175 °C. The device exhibits a temperature coefficient of 0.081 %/°C for VBR, ensuring predictable voltage drift across automotive temperature ranges.

|---|---|
Use Scenario: Protecting LIN bus and door module inputs from load dump and inductive switching spikes in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Bi-directional TVS placed between signal line and chassis ground to clamp transients before they reach microcontroller GPIO or LIN transceiver inputs. Use Value: Limits clamped voltage to 18.2 V, well below 24 V absolute maximum ratings of common automotive MCUs and transceivers, preventing latch-up or gate oxide damage. |
Use Scenario: Safeguarding half-duplex RS-485 transceivers (e.g., SN65HVD230) in factory automation networks exposed to motor drive noise and lightning-induced surges. IC Role / Device Role / Timing Role: Differential-line TVS connected across A/B bus lines and ground to suppress common-mode and differential-mode transients simultaneously. Use Value: Fast <1 ns response ensures clamping occurs before transceiver input stages experience destructive overvoltage, preserving data integrity and interface longevity. |
| Consumer Appliance Motor Drive Board | Smart Meter Power Supply Input |
Use Scenario: Shielding MCU-based washing machine control boards from commutation spikes generated by universal motor brushes and relay coil de-energization. IC Role / Device Role / Timing Role: Uni- or bi-directional TVS installed at motor driver IC power input and feedback signal nodes to absorb inductive kickback energy. Use Value: 600 W pulse rating handles repetitive 10–100 A spikes without degradation, extending board field life beyond 10,000 cycles. |
Use Scenario: Protecting AC/DC converter primary-side rectifier and secondary-side supervisor ICs in utility smart meters subjected to surge events per IEC 61000-4-5. IC Role / Device Role / Timing Role: Bi-directional TVS placed across bulk capacitor input to shunt line-to-ground surges before entering switching regulator stage. Use Value: 11.1 V VWM allows normal 9–10 V DC bias operation while clamping 1 kV/0.5 kA surges to ≤18.2 V - preventing brownout resets and regulator latch-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same VBR range (12.4–13.7 V), but SMC (DO-214AB) package - 1.5× larger footprint, higher IPPM (43.3 A), lower VC (21.5 V) | Better suited for higher-energy surges; requires PCB layout change due to surface-mount package and different thermal path | Select SMBJ13CA when higher surge margin or automated assembly is prioritized over axial-leaded serviceability. |
| 1.5KE13CA | Same DO-204AC package, but 1500 W rating (IPPM = 97.5 A, VC = 22.0 V); larger die, higher capacitance (~100 pF vs. ~50 pF) | Higher clamping voltage and junction capacitance may affect high-speed signal integrity in >1 Mbps interfaces | Choose 1.5KE13CA only when legacy 1.5 kW surge compliance (e.g., MIL-STD-1275) is mandatory and signal bandwidth is ≤100 kHz. |
Compared with SMBJ13CA and 1.5KE13CA, the P6KE13C-E3/73 offers optimal balance of compact axial form factor, 600 W surge capability, low 18.2 V clamping, and AEC-Q101 qualification - making it preferred for space-constrained, automotive-grade, through-hole assembled protection nodes where cost and reliability are tightly coupled.

FAQ
What is the polarity configuration of P6KE13C-E3/73?
The P6KE13C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking or polarity designation - either lead functions identically as anode or cathode depending on transient polarity. This makes P6KE13C-E3/73 ideal for protecting AC-coupled or differential signal lines like RS-485 or CAN without orientation concerns during assembly.
Does P6KE13C-E3/73 meet automotive qualification standards?
Yes, P6KE13C-E3/73 is AEC-Q101 qualified per the Vishay datasheet (Document Number: 88369, Revision: 18-Sep-12). This certification confirms its suitability for automotive applications including engine control, body electronics, and infotainment systems - validated for temperature cycling, humidity testing, mechanical shock, and surge endurance under defined stress conditions.
What is the maximum clamping voltage of P6KE13C-E3/73 and at what current is it specified?
The maximum clamping voltage (VC) of P6KE13C-E3/73 is 18.2 V, measured at a peak pulse current (IPPM) of 33.0 A using the standardized 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events, ensuring compatibility with 12 V system components rated to 20–24 V absolute maximum.
How does the thermal resistance of P6KE13C-E3/73 impact its surge handling capability?
P6KE13C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling rapid heat dissipation into PCB copper during transient events. This low RθJL sustains its 600 W peak pulse rating under short-duration surges and supports reliable operation up to +175 °C junction temperature - critical for under-hood automotive placement where ambient temperatures exceed 105 °C.
Is P6KE13C-E3/73 RoHS compliant and halogen-free?
Yes, P6KE13C-E3/73 carries the "E3" suffix indicating RoHS compliance per Directive 2011/65/EU, with matte tin-plated leads and halogen-free molding compound meeting JEDEC JS709A standards. It satisfies environmental requirements for automotive, industrial, and consumer electronics without compromising surge performance or long-term reliability.
