Product details
Overview
P6KE62CHE3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 62 V breakdown voltage (VBR min = 58.9 V, max = 65.1 V), 85 V maximum clamping voltage at 7.1 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs, ICs, and sensor interfaces against ESD, lightning-induced surges, and inductive switching transients.
For engineers reviewing the P6KE62CHE3/73 datasheet, P6KE62CHE3/73 pinout, P6KE62CHE3/73 application, or P6KE62CHE3/73 equivalent, this device is selected for high-surge-capability, low-clamping-voltage transient suppression in space-constrained DO-15 layouts - especially where bi-directional polarity, -55 °C to +175 °C operation, and RoHS-compliant AEC-Q101 qualification are required.
Technical Context
This bi-directional TVS operates symmetrically in both polarities with identical electrical characteristics - no cathode marking, no polarity dependency. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting reliable operation up to TJ = 175 °C. The device fails short-circuit under severe overload, enabling coordinated fuse/breaker protection without catastrophic open failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1.0 mA - defines precise voltage threshold where clamping begins in either direction |
| VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 7.1 A - clamping voltage during worst-case 600 W transient, limiting downstream stress |
| PPPM | 600 W (10/1000 µs) - peak surge handling capacity compatible with IEC 61000-4-5 Level 4 |
| TJ range | -55 °C to +175 °C - supports under-hood automotive, industrial motor control, and outdoor telecom environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy and matte tin leads |
| Qualification | AEC-Q101 qualified (HE3 suffix) - validated for automotive electronics per stress test requirements |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, 2.6 mm diameter × 7.6 mm length, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Bi-directional construction means no polarity marking - both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically during positive or negative overvoltage events - no orientation required on PCB |
| Lead 1 / Lead 2 | Thermal and mechanical interface | Leads serve as primary heat path to PCB copper; RθJL = 20 °C/W enables effective power dissipation into board traces |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable VBR tolerance across temperature and lifetime |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 4 kV surge (line-earth) without degradation when properly mounted |
| AEC-Q101 qualification (HE3) | Validated for automotive powertrain, body control, and ADAS modules requiring zero-failure field reliability |
| Bi-directional symmetry | Eliminates polarity-check step during assembly and supports AC-coupled or floating signal line protection |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and consumer enclosures |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package (SMB), 64 V VBR, 600 W, but lower IPPM (6.8 A) and higher VC (103 V) | Surface-mount only; unsuitable for through-hole legacy designs or high-thermal-mass leaded assemblies | Select SMBJ64CA only when board space is constrained and reflow soldering is available. |
| 1.5KE62CA | Same DO-15 package, 62 V VBR, but 1500 W rating (10/1000 µs) and higher VC (101 V); not AEC-Q101 qualified | Higher power handling but larger thermal footprint; lacks automotive qualification and tighter VBR tolerance | Choose 1.5KE62CA only for non-automotive industrial systems needing >600 W margin and accepting wider VC. |
Compared with SMBJ64CA and 1.5KE62CA, P6KE62CHE3/73 delivers optimal balance of AEC-Q101 compliance, tight 58.9–65.1 V VBR window, low 85 V clamping, and proven DO-15 manufacturability - making it preferred for cost-sensitive, thermally demanding, and automotive-qualified designs.

FAQ
What does the 'HE3' suffix indicate in P6KE62CHE3/73?
The HE3 suffix in P6KE62CHE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification - confirming that the P6KE62CHE3/73 has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing per automotive standards. This distinguishes it from commercial-grade E3 variants.
Is P6KE62CHE3/73 suitable for protecting RS-485 data lines?
Yes, P6KE62CHE3/73 is suitable for RS-485 bus protection when placed differentially across A/B lines or common-mode to ground. Its 85 V clamping voltage and bi-directional symmetry ensure symmetrical transient suppression without polarity concerns, and its 1.0 µA leakage at 53 V avoids signal distortion in half-duplex configurations.
How does P6KE62CHE3/73 compare to uni-directional P6KE62A in circuit design?
Unlike uni-directional P6KE62A (which requires correct cathode orientation and blocks forward conduction), P6KE62CHE3/73 provides identical clamping in both directions - eliminating polarity verification during placement and enabling use in AC-coupled, floating, or bidirectional signal paths. Its VBR and VC values match closely, but P6KE62CHE3/73 has no forward voltage drop specification since it conducts equally in both polarities.
Can P6KE62CHE3/73 be used in parallel for higher surge current handling?
No - P6KE62CHE3/73 should not be paralleled without external balancing resistors. Due to VBR tolerance (±5%), mismatched conduction onset can cause current hogging and premature failure. For higher IPPM, select a single higher-rated device like 1.5KE62CA or verify matched-bin pairing with Vishay's characterization data before parallel implementation.
What is the maximum recommended PCB trace width for P6KE62CHE3/73 leads to maintain thermal performance?
To sustain rated 600 W pulse power without exceeding TJ = 175 °C, each P6KE62CHE3/73 lead should connect to ≥250 mil (6.35 mm) wide, 2 oz copper traces extending ≥1 inch from the device body. This ensures adequate heat spreading given RθJL = 20 °C/W - verified in Vishay's thermal derating curves (Fig. 5) for DO-15 mounting on FR-4.
