Product details
Overview
P6KE6.8A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 6.45 V minimum breakdown voltage (VBR), 5.8 V stand-off voltage (VWM), 10.5 V maximum clamping voltage at 57.1 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and DO-15 package. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails.
For engineers reviewing the P6KE6.8A-E3/73 datasheet, P6KE6.8A-E3/73 pinout, P6KE6.8A-E3/73 application, or P6KE6.8A-E3/73 equivalent, key selection criteria include clamping voltage under 10.5 V at 57.1 A, 5.8 V working voltage margin for 5 V systems, unidirectional polarity with cathode band marking, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (5.8 V), enters avalanche breakdown at VBR (6.45–7.14 V), and limits transient voltage to ≤10.5 V at rated IPPM (57.1 A). Its glass-passivated junction ensures stable leakage (<1000 μA at VWM) and fast response time (<1 ns).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above 25 °C ambient per Fig. 2. It supports repetitive 0.01% duty cycle pulses and meets UL 94 V-0 flammability requirements in its molded DO-15 epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - Maximum continuous reverse operating voltage before leakage exceeds 1000 μA; sets safe margin for 5 V rail protection. |
| VBR @ IT = 10 mA | 6.45–7.14 V - Breakdown voltage range defining reliable avalanche initiation; ensures consistent turn-on across production lots. |
| VC @ IPPM = 57.1 A | 10.5 V - Clamped voltage during worst-case 600 W transient; limits stress on downstream 12 V tolerant components. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IFSM | 100 A - Non-repetitive forward surge current (8.3 ms half-sine); supports single-event load dump survival in automotive 12 V systems. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood environments without thermal shutdown. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded, RoHS-compliant, matte tin-plated leads. Cathode identified by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or low-voltage reference; forms shunt path during reverse transients. |
| Cathode (banded end) | Reverse voltage sensing / high-side connection | Connected to protected line (e.g., 5 V rail); avalanche conduction occurs when line voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, low-leakage avalanche performance over temperature and lifetime; eliminates surface degradation risks. |
| 600 W peak pulse power (10/1000 μs) | Validates immunity to severe lightning-induced surges and inductive switching spikes in industrial motor drives. |
| AEC-Q101 qualified (E3 suffix variant) | Confirms reliability for automotive applications including body control modules and infotainment power inputs. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients; critical for protecting CMOS inputs with tight voltage tolerances. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: 12 V battery feed to body control module exposed to load dump (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VIN and GND to clamp transients above 13.5 V. Use Value: Limits peak voltage to ≤10.5 V at 57.1 A, preventing damage to LDO regulators and microcontroller power pins. | Use Scenario: Analog output line (0–5 V) from pressure sensor in factory automation PLC I/O module. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on signal trace to suppress ESD (IEC 61000-4-2) and cable discharge events. Use Value: Sub-1 ns response and 10.5 V clamping prevent latch-up or gate oxide rupture in op-amp input stages. |
| Consumer USB Port Surge Guard | Telecom DC Power Feed Protection |
Use Scenario: +5 V VBUS line in USB 2.0 host port subjected to hot-plug induced transients and ESD. IC Role / Device Role / Timing Role: Primary unidirectional TVS on VBUS rail upstream of USB controller and power switch. Use Value: 5.8 V VWM provides 0.2 V margin above nominal 5 V, while 10.5 V VC avoids false overvoltage shutdown. | Use Scenario: -48 V DC telecom power feed entering remote radio head enclosure with long external cabling. IC Role / Device Role / Timing Role: Reverse-polarity connected unidirectional TVS (cathode to -48 V, anode to GND) for negative rail clamping. Use Value: Withstands 100 A IFSM, enabling survival of accidental short-circuit recovery events without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | Same VWM (5.8 V), VC = 11.2 V at 53.3 A, SMC package (higher thermal mass, lower RθJA). | Better suited for higher average power dissipation; requires PCB footprint change from DO-15 to SMC. | Select SMBJ6.8A when board layout allows larger package and thermal management demands exceed DO-15 capability. |
| 1.5KE6.8A | Same VWM/VBR specs, but 1500 W PPPM, DO-201AD package, higher IPPM (123 A), VF = 3.5 V. | Higher surge capacity for legacy designs requiring >600 W margin; larger DO-201AD footprint and lead spacing. | Choose 1.5KE6.8A only if system-level surge testing requires >600 W headroom and space permits larger package. |
Compared with SMBJ6.8A and 1.5KE6.8A, P6KE6.8A-E3/73 offers optimal cost-performance balance for space-constrained 600 W applications in DO-15 footprint, with verified AEC-Q101 compliance and tighter VBR tolerance (±5%) than 1.5KE series.

FAQ
What is the clamping voltage of P6KE6.8A-E3/73 and how is it measured?
The P6KE6.8A-E3/73 has a maximum clamping voltage (VC) of 10.5 V, measured at a peak pulse current (IPPM) of 57.1 A using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the upper limit of voltage seen by protected circuitry during a standardized surge event and is guaranteed across temperature and production lot variations for the P6KE6.8A-E3/73.
Is P6KE6.8A-E3/73 suitable for automotive applications?
Yes, the P6KE6.8A-E3/73 variant with E3 suffix is AEC-Q101 qualified per the Vishay datasheet (Doc. #88369, Rev. 27-Sep-2021), confirming its reliability for automotive use cases including power supply input protection in body control modules and infotainment systems. The P6KE6.8A-E3/73 operates from –55 °C to +175 °C and withstands load dump and ISO 7637-2 transients.
How does the DO-15 package of P6KE6.8A-E3/73 affect thermal performance?
The DO-15 package of P6KE6.8A-E3/73 delivers RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling 5.0 W steady-state dissipation at TL = 75 °C. Its axial-leaded form supports manual or wave soldering per JESD 22-B106 (275 °C, 10 s), and thermal derating follows Fig. 2 in the P6KE6.8A-E3/73 datasheet.
What is the difference between P6KE6.8A-E3/73 and P6KE6.8CA-E3/73?
P6KE6.8A-E3/73 is unidirectional with cathode band marking and specified for reverse-biased clamping only; P6KE6.8CA-E3/73 is bidirectional, symmetrical, and lacks polarity marking. Their VBR and VC values differ: P6KE6.8CA-E3/73 has VBR = 6.45–7.14 V in both directions and higher VC due to dual-junction architecture. Use P6KE6.8A-E3/73 for DC rail protection, not AC or differential lines.
Does P6KE6.8A-E3/73 meet RoHS and REACH requirements?
Yes, the "E3" suffix in P6KE6.8A-E3/73 explicitly denotes RoHS compliance per Vishay's ordering information (Document #88369).
