Product details
Overview
P6KE10A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. 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 protection of MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD events in automotive and industrial control systems.
For engineers reviewing the P6KE10A-E3/73 datasheet, P6KE10A-E3/73 pinout, P6KE10A-E3/73 application, or P6KE10A-E3/73 equivalent, this device is evaluated for fast-response surge suppression in 12 V nominal systems where clamping voltage margin, thermal derating above 25 °C, and AEC-Q101 qualification status are critical selection criteria.
Technical Context
This unidirectional TVS operates with a glass-passivated junction and exhibits low incremental surge resistance, enabling stable clamping performance under repetitive 10/1000 μs transients at 0.01 % duty cycle. Its 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation up to 5.0 W on infinite heatsink at TL = 75 °C.
The device delivers 14.5 V clamping voltage at 41.4 A IPPM while maintaining 9.50–10.5 V breakdown voltage (VBR) at 1.0 mA test current, and shows +0.073 %/°C temperature coefficient - ensuring predictable voltage drift across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single high-energy surges without degradation in standard PCB mount |
| Stand-off Voltage (VWM) | 8.55 V - blocks normal 12 V rail operation while remaining fully off below transient threshold |
| Breakdown Voltage (VBR) | 9.50–10.5 V at 1.0 mA - defines precise turn-on threshold for controlled avalanche conduction |
| Maximum Clamping Voltage (VC) | 14.5 V at 41.4 A IPPM - limits protected circuit voltage during worst-case surge event |
| Peak Pulse Current (IPPM) | 41.4 A - quantifies maximum transient energy absorption capability per IEC 61000-4-5 waveform |
| Operating Temperature Range | -55 °C to +175 °C - supports under-hood automotive and high-temp industrial environments |
| Thermal Resistance (Junction-to-Lead) | 20 °C/W - enables effective heat transfer to PCB copper pour or lead frame for sustained reliability |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode identified by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected line | Connected to ground or return path; carries full surge current during clamping |
| Cathode | High-side connection to protected line | Marked end; connects to power rail or signal line requiring overvoltage protection |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power (10/1000 μs) | Provides industry-standard surge immunity for IEC 61000-4-5 Level 3/4 compliance in compact DO-15 form factor |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics use including engine control units and body electronics modules |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes voltage overshoot during transient events, protecting downstream 15 V tolerant components |
| Solder dip rated 275 °C for 10 s | Ensures compatibility with standard wave soldering processes without parametric shift or bond degradation |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between power input and LDO/regulator input. Use Value: Limits transient excursions to ≤14.5 V, preventing regulator latch-up or internal FET failure in microcontrollers. |
Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed through long harnesses in factory automation. IC Role / Device Role / Timing Role: Point-of-entry protection on differential or single-ended signal lines before ADC input stage. Use Value: Suppresses inductive kickback from nearby solenoid actuation, preserving signal integrity and avoiding ADC saturation. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
Use Scenario: AC/DC adapter secondary-side DC output feeding USB-C PD controller or PMIC. IC Role / Device Role / Timing Role: Secondary-side TVS parallel to bulk capacitor, upstream of DC-DC converter. Use Value: Absorbs reverse-polarity misconnection surges and rectifier ringback spikes without degrading efficiency. |
Use Scenario: Low-voltage data lines (e.g., RS-485, CAN) entering telecom base station cabinets. IC Role / Device Role / Timing Role: First-stage protection on line driver/receiver side, before series termination resistor. Use Value: Clamps lightning-induced common-mode transients to <15 V, meeting GR-1089-CORE Level 3 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package; 600 W rating; 10.0–11.1 V VBR; 17.0 V VC at 35.3 A | Surface-mount footprint; higher clamping voltage; lower thermal resistance (junction-to-PCB) | Select when board space is constrained and reflow assembly is preferred over axial through-hole mounting. |
| 1.5KE10A | DO-201AD package; 1500 W rating; 9.5–10.5 V VBR; 14.5 V VC at 103 A | Higher power handling; larger package; same VBR/VC but significantly higher IPPM capability | Select when system-level surge testing requires >600 W margin or legacy DO-201AD footprint compatibility is mandatory. |
Compared with P6KE10A-E3/73, SMBJ10A offers SMT compatibility at the cost of higher clamping voltage and reduced thermal mass, while 1.5KE10A provides 2.5× peak power headroom in a larger axial package - making P6KE10A-E3/73 optimal for cost-sensitive, space-constrained 12 V DC protection where 600 W suffices.

FAQ
What is the clamping voltage of P6KE10A-E3/73 at its rated peak pulse current?
The P6KE10A-E3/73 has a maximum clamping voltage (VC) of 14.5 V when subjected to its specified peak pulse current (IPPM) of 41.4 A under the 10/1000 μs waveform. This value is measured per JEDEC standards and ensures protected circuits remain within safe voltage limits during transient events. The P6KE10A-E3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE10A-E3/73 suitable for automotive applications?
Yes, the P6KE10A-E3/73 is AEC-Q101 qualified (as indicated by the HE3 suffix variant), and the E3 suffix meets JESD 201 Class 1A whisker testing. While P6KE10A-E3/73 itself is commercial-grade, its construction, thermal specs (-55 °C to +175 °C TJ), and surge robustness make it widely deployed in non-safety-critical automotive subsystems such as body control modules and infotainment power supplies. For full AEC-Q101 compliance, specify P6KE10AHE3/73.
How does the P6KE10A-E3/73 differ from bidirectional variants like P6KE10CA?
The P6KE10A-E3/73 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6KE10CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The P6KE10A-E3/73 has a forward voltage drop (~3.5 V at 50 A), while P6KE10CA does not conduct in forward bias. Use P6KE10A-E3/73 for DC rail protection and P6KE10CA for AC or floating signal line protection.
What is the thermal resistance and power derating behavior of P6KE10A-E3/73?
The P6KE10A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a junction-to-ambient value of 75 °C/W. Its 5.0 W power dissipation rating applies only at TL = 75 °C on an infinite heatsink; above 25 °C ambient, linear derating begins per Figure 2 in the datasheet. At 100 °C ambient, usable power drops to ~3.0 W - a key constraint for high-temperature enclosure designs using P6KE10A-E3/73.
Can P6KE10A-E3/73 be used in place of P6KE10A without modification?
Yes, P6KE10A-E3/73 is a RoHS-compliant, commercial-grade variant of P6KE10A with identical electrical specifications, DO-15 packaging, and pinout. The "E3" suffix denotes matte tin plating and JESD 201 Class 1A whisker resistance; "/73" indicates 7-inch reel packaging. No PCB layout or schematic changes are required when substituting P6KE10A-E3/73 for legacy P6KE10A in new production.
