Product details
Overview
P6KE56-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 56 V breakdown voltage (VBR = 53.2–58.8 V at IT = 1.0 mA), 77.0 V maximum clamping voltage (VC) at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive infotainment power inputs and industrial sensor interface protection.
For engineers reviewing the P6KE56-E3/73 datasheet, P6KE56-E3/73 pinout, P6KE56-E3/73 application, or P6KE56-E3/73 equivalent, this device delivers verified AEC-Q101 qualification, DO-15 package compatibility, low thermal resistance (RθJL = 20 °C/W), and precise clamping performance critical for IEC 61000-4-5 surge immunity design.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches into low-impedance conduction to divert transient energy away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM = 47.8 V) and fast response (<1.0 ns).
Thermal design is enabled by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting reliable operation up to TJ = +175 °C. The 100 A IFSM rating (8.3 ms half-sine) allows robust handling of repetitive inductive-switching surges without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 47.8 V - maximum continuous working voltage; ensures zero leakage during normal 48 V rail operation |
| VC @ IPPM | 77.0 V at 7.8 A - limits protected circuit voltage to safe level during 600 W transient events |
| PPPM | 600 W - peak surge power handling per 10/1000 µs waveform, validated for IEC 61000-4-5 Level 4 compliance |
| IFSM | 100 A - withstands 8.3 ms inductive turn-off surges without bond-wire fusing or parameter shift |
| TJ max. | +175 °C - enables placement near hot components (e.g., power MOSFETs) without derating penalties |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molding and matte tin plating |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking. Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102; qualified to JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; conducts only during forward-biased transients or ESD events |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 48 V supply); initiates clamping when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and <1.0 µA leakage at VWM across -55 °C to +175 °C |
| 600 W peak pulse power (10/1000 µs) | Validated for repeated IEC 61000-4-5 surge testing without parameter drift or catastrophic failure |
| AEC-Q101 qualified | Qualified for automotive powertrain and body electronics per stress test requirements (HTOL, TC, UHAST) |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes voltage overshoot on protected nodes - critical for 5 V/3.3 V logic interfacing with 48 V systems |
| RoHS-compliant, commercial grade (E3 suffix) | Meets EU RoHS Directive 2011/65/EU; no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | DO-214AA package; 58 V VBR; 600 W rating; lower RθJA (50 °C/W) but higher VC (93.6 V) | Suitable for surface-mount designs where board space is constrained; less effective clamping on high-current surges | Select SMBJ58A when SMT assembly is required and clamping voltage margin >93 V is acceptable |
| 1.5KE56A | Same DO-15 package; identical VBR and VC; 1500 W rating but larger footprint and higher cost | Better suited for legacy designs requiring higher surge margin; not AEC-Q101 qualified | Choose 1.5KE56A only if 1500 W peak power is mandated and automotive qualification is not required |
Compared with SMBJ58A and 1.5KE56A, P6KE56-E3/73 offers optimal balance of AEC-Q101 qualification, tight VC (77.0 V), DO-15 compatibility, and cost efficiency for volume automotive and industrial applications - without compromising surge reliability or thermal performance.

FAQ
What is the breakdown voltage tolerance for P6KE56-E3/73?
The P6KE56-E3/73 has a specified breakdown voltage range of 53.2 V to 58.8 V at test current IT = 1.0 mA, representing ±5 % tolerance around the nominal 56 V rating. This tight tolerance ensures consistent clamping behavior across production lots and temperature ranges from -55 °C to +175 °C, critical for predictable overvoltage protection in safety-critical systems.
Is P6KE56-E3/73 suitable for automotive applications?
Yes, P6KE56-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use per the Vishay datasheet revision 18-Sep-12. Its construction - including glass-passivated junction, DO-15 package with matte tin leads, and operation up to +175 °C junction temperature - meets stress test requirements for powertrain and body electronics, making it appropriate for 12 V/48 V battery line protection in vehicles.
What is the maximum clamping voltage of P6KE56-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE56-E3/73 is 77.0 V at peak pulse current IPPM = 7.8 A with a 10/1000 µs waveform. This value is guaranteed across all units and represents the upper limit of voltage seen by protected circuitry during worst-case transient events - essential for verifying that downstream components remain within absolute maximum ratings.
Does P6KE56-E3/73 have RoHS compliance documentation?
Yes, P6KE56-E3/73 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU. Vishay certifies that this part contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and its matte tin plating satisfies JESD 201 Class 1A whisker resistance requirements - confirmed in Document Number 88369 and Vishay's Material Category Policy (Doc. 99912).
How does P6KE56-E3/73 compare to bi-directional TVS variants like P6KE56CA?
P6KE56-E3/73 is unidirectional and features a cathode band for polarity identification, while P6KE56CA is bidirectional with no marking and symmetrical clamping in both directions. The unidirectional P6KE56-E3/73 provides lower leakage (<1.0 µA at 47.8 V) and tighter VBR control for DC rail protection, whereas P6KE56CA suits AC-coupled or floating signal lines - selection depends strictly on circuit topology and surge polarity requirements.
