Product details
Overview
P6KE56-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 56 V breakdown voltage (VBR min/max = 53.2–58.8 V), 47.8 V standoff voltage (VWM), 77.0 V clamping voltage at 7.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P6KE56-E3/54 datasheet, P6KE56-E3/54 pinout, P6KE56-E3/54 application, or P6KE56-E3/54 equivalent, key selection criteria include clamping performance under 8.3 ms surge events, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and compatibility with J-STD-002 solderability requirements.
Technical Context
The P6KE56-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient overvoltages induced by inductive switching or ESD. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
It sustains 100 A non-repetitive forward surge current (IFSM) at 8.3 ms half-sine, dissipates 5.0 W continuously on infinite heatsink at TL = 75 °C, and maintains operation across -55 °C to +175 °C junction temperature range - supporting automotive and industrial environments where thermal cycling and high ambient temperatures are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V - defines guaranteed avalanche initiation window at 1.0 mA test current; ensures consistent turn-on across production lots |
| VWM | 47.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA; sets safe DC bias margin |
| VC @ IPPM | 77.0 V at 7.8 A - clamping voltage during 10/1000 µs transient; determines protected circuit's maximum stress level |
| PPPM | 600 W - peak pulse power handling capability; defines survivability against lightning-induced surges per IEC 61000-4-5 |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables accurate PCB trace thermal design for sustained surge duty |
| TJ max. | +175 °C - maximum junction temperature; supports under-hood automotive use without derating at 125 °C ambient |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC standard |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 22-B102 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive transients when cathode is biased higher |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential rail (e.g., VCC); initiates avalanche breakdown when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, low-noise avalanche characteristics and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without external series impedance |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., EFT bursts), improving protection margin |
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics applications requiring zero early-life failure |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Ensures lead finish integrity after reflow and long-term storage; eliminates tin whisker risk in high-reliability systems |

Use Scenario: Safeguarding PoE-powered Ethernet switch ports against lightning-induced surges on data pairs and auxiliary power lines. IC Role / Device Role / Timing Role: Secondary-level TVS used in conjunction with gas discharge tubes (GDTs) to handle residual let-through energy after primary suppression. Use Value: 600 W rating allows absorption of 10/1000 µs surges exceeding 100 A after GDT crowbarring, eliminating need for additional MOV stages. |
Use Scenario: Protecting AC-DC adapter primary-side rectifier and bulk capacitor from differential-mode surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Unidirectional clamp installed across bridge rectifier output to clamp overvoltage before it reaches bulk capacitor and controller IC. Use Value: 47.8 V VWM permits use with 36 V nominal DC bus, while 77.0 V VC ensures bulk cap rated ≥80 V remains within safe operating area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | DO-214AA package; 58 V VBR; 600 W rating; RθJA = 40 °C/W vs. 75 °C/W for P6KE56-E3/54 | Surface-mount alternative with higher thermal resistance; requires larger copper area for same power dissipation | Select SMBJ58A when board space is constrained and reflow assembly is preferred over axial through-hole mounting |
| 1.5KE56A | Same DO-204AC package; identical VBR/VC specs; 1500 W peak power rating; higher IPPM (17.3 A) | Higher surge capacity suits applications exposed to repeated heavy-duty transients (e.g., industrial motor drives) | Choose 1.5KE56A when system-level surge testing requires >600 W margin or legacy designs mandate backward-compatible footprint |
Compared with SMBJ58A and 1.5KE56A, the P6KE56-E3/54 offers optimal balance of axial-mount mechanical robustness, AEC-Q101 qualification, and cost-effective 600 W protection - making it ideal for automotive body controllers and industrial power supplies where through-hole reliability and qualification compliance are prioritized over ultra-high surge headroom or SMT density.

FAQ
What is the maximum clamping voltage of the P6KE56-E3/54 under standard test conditions?
The P6KE56-E3/54 has a maximum clamping voltage (VC) of 77.0 V when subjected to its rated peak pulse current of 7.8 A using the 10/1000 µs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during a defined transient event. The P6KE56-E3/54 achieves this clamping performance while maintaining low incremental surge resistance, ensuring predictable protection behavior across production units.
Is the P6KE56-E3/54 suitable for automotive applications?
Yes, the P6KE56-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including body control modules, lighting drivers, and sensor interfaces. It operates reliably from -55 °C to +175 °C, withstands 100 A surge current per 8.3 ms half-sine, and meets JESD 201 Class 1A whisker testing - all critical for under-hood and chassis-mounted electronics. The P6KE56-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified devices table.
What does the "E3/54" suffix indicate in P6KE56-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/54" indicates the preferred package code for 13-inch paper tape and reel packaging, with a base quantity of 4000 units per reel. This packaging format ensures automated placement compatibility and traceable lot control for high-volume manufacturing of the P6KE56-E3/54.
How does the P6KE56-E3/54 differ from bi-directional TVS diodes like P6KE56CA?
The P6KE56-E3/54 is unidirectional and features a cathode band for polarity identification, allowing it to block reverse DC voltage while clamping positive transients - ideal for DC-biased lines. In contrast, P6KE56CA is bi-directional with no polarity marking and clamps transients of either polarity, suited for AC lines or floating signal paths. The P6KE56-E3/54 exhibits lower leakage below VWM and higher forward surge capability (100 A IFSM) than its bi-directional counterpart.
What thermal considerations apply when using the P6KE56-E3/54 in continuous operation?
The P6KE56-E3/54 has a thermal resistance of 20 °C/W from junction to lead (RθJL) and 75 °C/W from junction to ambient (RθJA). For continuous power dissipation, its 5.0 W rating applies only with infinite heatsinking at TL = 75 °C; derating is required above that lead temperature. In typical PCB layouts, thermal relief traces and copper pour under the leads directly impact steady-state temperature rise - the P6KE56-E3/54 must be mounted with adequate copper area to avoid exceeding +175 °C junction temperature during surge recovery cycles.
