Product details
Overview
P6KE6V8A from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 5.8V reverse standoff voltage (VRWM), 6.45V minimum breakdown voltage (VBR), 10.5V maximum clamping voltage (VC) at 57A peak pulse current, and DO-15 glass-passivated package-used in automotive body control modules to suppress load-dump transients.
For engineers reviewing the P6KE6V8A datasheet, P6KE6V8A pinout, P6KE6V8A application, or P6KE6V8A equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, 600W single-pulse surge capability, unidirectional polarity alignment with DC rail orientation, and DO-15 through-hole mounting compatibility with legacy PCB layouts.
Technical Context
This TVS operates as a voltage-clamped shunt device triggered by avalanche breakdown above its specified VBR. Its fast response time (<1 ns) ensures suppression before downstream components experience overstress, and its glass-passivated die construction provides stable leakage performance across temperature.
The device complies with IEC 61000-4-5 Level 4 surge immunity requirements when applied with appropriate series impedance. Thermal resistance values (RθJA = 75°C/W, RθJC = 20°C/W) define its steady-state dissipation limit of 5.0W at TL = +75°C on a 40mm² copper land.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000μs waveform-defines maximum transient energy absorption without failure |
| Reverse Standoff Voltage (VRWM) | 5.8V-maximum continuous DC or RMS voltage the device blocks without significant leakage |
| Breakdown Voltage (VBR) | 6.45V min @ 10mA-avalanche onset threshold ensuring reliable triggering before protected circuit exceeds rating |
| Clamping Voltage (VC) | 10.5V max @ 57A IPP-voltage seen by downstream circuit during worst-case surge, critical for IC survivability |
| Package | DO-15-standard axial-leaded through-hole package with 0.4g mass, UL 94V-0 molded plastic housing |
| Thermal Resistance (RθJA) | 75°C/W-junction-to-ambient thermal path limiting sustained power handling in still air |
| Operating Temperature | -55°C to +175°C-supports under-hood automotive environments and industrial power supply locations |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode indicated by band on body. Leads are tin-plated, solderable per MIL-STD-202 Method 208, with 9.5mm lead length standard for thermal derating calculations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; defines unidirectional conduction direction |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 5V rail); avalanche breakdown occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables robust protection against ISO 7637-2 Pulse 5a (load dump) transients in 12V automotive systems |
| Glass-passivated die construction | Ensures long-term stability of leakage current and breakdown voltage under humidity and thermal cycling |
| 10.5V clamping voltage at 57A | Provides ≥1.5V margin below typical 12V system overvoltage thresholds, preventing latch-up in connected logic |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation, supporting automotive PPAP submissions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | Same VRWM (6.8V), lower PPK (600W), but SMC package (surface-mount) with higher VC (11.2V @ 53.5A) | Requires PCB redesign for SMD placement; better suited for space-constrained consumer electronics | Select when board real estate is limited and reflow assembly is preferred over through-hole |
| 1.5KE6.8A | Higher PPK (1500W), same DO-15 package, but larger physical size and higher clamping (10.5V @ 143A) | Overqualified for 600W needs; introduces unnecessary thermal mass and cost in compact designs | Select only if legacy 1.5KE footprint compatibility is required and surge margin must exceed 1kW |
Compared with SMBJ6.8A and 1.5KE6.8A, P6KE6V8A offers optimal balance of proven DO-15 through-hole reliability, precise 10.5V clamping for 5V-system compatibility, and cost-effective 600W surge handling without over-engineering.

FAQ
Is P6KE6V8A RoHS compliant and halogen-free?
Yes, P6KE6V8A features a lead-free finish compliant with EU Directive 2011/65/EU (RoHS 2), including all applicable exemptions. Diodes Incorporated confirms it meets their internal "Green" definition-fully halogen- and antimony-free-as documented in their lead-free policy portal.
What is the maximum allowable ambient temperature for continuous operation?
P6KE6V8A supports continuous operation from -55°C to +175°C junction temperature. At TA = +25°C, its steady-state power dissipation is 5.0W when mounted on a 40mm² copper land at TL = +75°C; derating follows the curve in Figure 4, reaching zero dissipation at +175°C ambient.
Can P6KE6V8A be used in bidirectional configurations?
No-P6KE6V8A is unidirectional only. The bidirectional variant is designated P6KE6V8CA (note the 'C' suffix). Their pinouts differ: P6KE6V8A has a cathode band indicating polarity, while P6KE6V8CA omits the band and conducts symmetrically in both directions.
How does P6KE6V8A compare to P6KE6.8A in marking and electrical specs?
P6KE6V8A and P6KE6.8A refer to the same device-the 'V' denotes voltage designation per Diodes' naming convention. Electrical specs (VRWM = 5.8V, VBR = 6.45V min, VC = 10.5V) and DO-15 packaging are identical; no functional or parametric difference exists between the two part number forms.
