Product details
Overview
P6KE47HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 47 V breakdown voltage (VBR min/max = 44.7–49.4 V), 40.2 V stand-off voltage (VWM), 64.8 V clamping voltage (VC) at 9.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE47HE3/54 datasheet, P6KE47HE3/54 pinout, P6KE47HE3/54 application, or P6KE47HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 175 °C maximum junction temperature, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR, it avalanches into low-impedance conduction, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under thermal cycling.
Designed for uni-directional DC protection only, P6KE47HE3/54 exhibits 1.0 µA max reverse leakage at VWM, 3.5 V max forward voltage at 50 A, and thermal resistance of 20 °C/W (junction-to-lead), enabling effective heat dissipation in compact PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V - defines guaranteed avalanche initiation range at 1.0 mA test current; ensures consistent turn-on across production lots |
| VWM | 40.2 V - maximum continuous reverse operating voltage; must exceed system nominal DC rail (e.g., 36 V automotive) to avoid leakage-induced power loss |
| VC @ IPPM | 64.8 V at 9.3 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected IC's absolute maximum rating |
| PPPM | 600 W - peak pulse power handling capability; validates robustness against ISO 7637-2 Pulse 5a (load dump) up to specified current |
| TJ max | +175 °C - enables operation in under-hood automotive environments without derating below ambient 125 °C |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.300" lead spacing; compatible with legacy through-hole assembly and wave soldering |
| Qualification | AEC-Q101 qualified - certified for automotive electronic systems requiring zero defects in high-reliability applications |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge events (e.g., reverse polarity connection) |
| Cathode | Reverse-biased avalanche terminal | Connected to protected line (e.g., +12 V rail); initiates clamping when voltage exceeds VBR; marked with color band |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and low leakage drift over 1000+ thermal cycles (−55 °C to +175 °C) |
| 600 W peak pulse power (10/1000 µs) | Withstands automotive load-dump surges (ISO 7637-2 Pulse 5a) without degradation when mounted per JEDEC standards |
| AEC-Q101 qualification | Validated for automotive under-hood use including HTOL, temperature cycling, and bond wire pull tests per AEC specification |
| Low incremental surge resistance | Enables tight VC control (<65 V) at 9.3 A, limiting transient overshoot on 3.3 V/5 V logic supply rails |
| Solder dip rated 275 °C / 10 s | Supports lead-free reflow and wave soldering processes without delamination or parameter shift |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs against load-dump transients (up to 60 V, 200 ms duration) per ISO 7637-2. IC Role / Device Role: Primary shunt clamp on main power input, placed upstream of DC/DC converter and MCU power pins. Use Value: Limits voltage seen by downstream regulators to ≤64.8 V, preventing latch-up or oxide rupture in 65 V-rated input stages. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC analog inputs exposed to field wiring surges. IC Role / Device Role: Point-of-entry TVS on twisted-pair signal lines before instrumentation amplifier input stage. Use Value: Clamps induced EFT bursts (IEC 61000-4-4) to <65 V while maintaining <1 µA leakage at 40.2 V, preserving signal integrity. |

|
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters subjected to lightning-induced surges on mains-connected DC outputs. IC Role / Device Role: Final-stage clamp on regulated 5 V/12 V output rail before USB or peripheral connectors. Use Value: Absorbs 600 W pulses without failure, eliminating need for redundant Zener strings and reducing BOM count by one component. |
Use Scenario: Front-end protection for Ethernet PHY interfaces on telecom line cards exposed to induced surges from nearby power cables. IC Role / Device Role: Bi-directional-capable variant not used; this uni-directional part applied on DC bias rails feeding PoE controllers. Use Value: Provides 175 °C junction rating for sustained operation in sealed chassis with limited airflow, avoiding thermal shutdown during repeated surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45A | DO-214AA package; 45 V VWM, 64.8 V VC @ 9.2 A; same PPPM but surface-mount | Requires SMT layout change; unsuitable for through-hole legacy designs or high-vibration mechanical retention | Select SMBJ45A only when board space constraints mandate SMT and thermal pad design supports RθJA ≤ 50 °C/W |
| P6KE47A-E3/54 | Identical electrical specs and DO-204AC package; differs only in qualification - commercial grade (non-AEC-Q101) | Not approved for automotive safety-critical modules; acceptable for industrial or consumer applications with lower reliability requirements | Choose P6KE47A-E3/54 for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMBJ45A and P6KE47A-E3/54, P6KE47HE3/54 uniquely delivers AEC-Q101 assurance in a proven through-hole package - critical for automotive Tier-1 suppliers requiring audit-ready qualification evidence and mechanical robustness in high-shock environments.

FAQ
What is the maximum clamping voltage of P6KE47HE3/54 and under what test condition?
The maximum clamping voltage (VC) of P6KE47HE3/54 is 64.8 V, measured at a peak pulse current (IPPM) of 9.3 A using the standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the upper limit of voltage imposed on protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range.
Is P6KE47HE3/54 suitable for bi-directional signal line protection?
No, P6KE47HE3/54 is a uni-directional TVS diode and must be used only in DC applications with defined polarity. For bi-directional protection (e.g., AC-coupled data lines), the CA-suffixed variant P6KE47CA or equivalent is required. Using P6KE47HE3/54 on AC signals risks forward conduction during negative half-cycles and invalidates clamping behavior.
Does P6KE47HE3/54 meet RoHS and halogen-free requirements?
Yes, P6KE47HE3/54 is RoHS-compliant per Directive 2011/65/EU and halogen-free per JEDEC JS709A. The HE3 suffix confirms compliance with JESD 201 Class 2 whisker testing, and the molding compound meets UL 94 V-0 flammability rating - all verified in Vishay's material declaration documentation.
What is the thermal resistance from junction to lead (RθJL) for P6KE47HE3/54?
The typical thermal resistance from junction to lead (RθJL) for P6KE47HE3/54 is 20 °C/W, as specified in the Vishay datasheet. This value enables accurate thermal modeling when mounting on PCBs with copper pour or short lead traces, supporting reliable operation at full 600 W pulse rating without exceeding TJ = 175 °C under pulsed conditions.
How does the AEC-Q101 qualification of P6KE47HE3/54 impact its use in automotive designs?
AEC-Q101 qualification certifies that P6KE47HE3/54 has passed accelerated stress tests including HTOL, temperature cycling, and bond wire strength validation - making it acceptable for automotive powertrain, chassis, and body electronics. Unlike commercial-grade variants, P6KE47HE3/54 provides documented failure mode analysis and lot-level traceability required by Tier-1 OEMs.
