Product details
Overview
P6KE8.2CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 7.79–8.61 V breakdown voltage at 10 mA, 7.02 V stand-off voltage, 12.1 V maximum clamping voltage at 49.6 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE8.2CAHE3/54 datasheet, P6KE8.2CAHE3/54 pinout, P6KE8.2CAHE3/54 application, or P6KE8.2CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C junction temperature rating, low incremental surge resistance, and compliance with UL 497B for telecom/sensor protection.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 μA leakage at 7.02 V), but triggers into low-impedance conduction when transient voltage exceeds its breakdown range. Its glass-passivated junction ensures stable VBR tolerance and fast response time (<1 ns).
The bidirectional architecture enables symmetric clamping in AC-coupled or floating signal paths without polarity concerns. Thermal design relies on RθJL = 20 °C/W to lead and RθJA = 75 °C/W to ambient, supporting 5.0 W steady-state dissipation at TL = 75 °C with appropriate PCB copper area.
Key Specifications

FAQ
What is the breakdown voltage range of the P6KE8.2CAHE3/54?
The P6KE8.2CAHE3/54 has a guaranteed breakdown voltage range of 7.79 V to 8.61 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight VBR window ensures consistent triggering behavior across temperature and production lots, critical for protecting sensitive 5 V or 3.3 V logic interfaces without false triggering.
Is the P6KE8.2CAHE3/54 suitable for automotive applications?
Yes, the P6KE8.2CAHE3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature. Its DO-15 package, glass-passivated junction, and UL 497B recognition make P6KE8.2CAHE3/54 appropriate for engine bay sensors, body control modules, and infotainment power rails where transient immunity and long-term reliability are required.
How does the bidirectional configuration of P6KE8.2CAHE3/54 affect its use in circuit design?
The bidirectional configuration of P6KE8.2CAHE3/54 allows symmetric clamping of both positive and negative transients without regard to polarity-ideal for AC-coupled signal lines, differential buses like RS-485, or floating power domains. Unlike unidirectional TVS diodes, P6KE8.2CAHE3/54 requires no cathode orientation during placement, simplifying layout and reducing assembly errors.
What is the maximum clamping voltage of P6KE8.2CAHE3/54 under surge conditions?
The P6KE8.2CAHE3/54 clamps to a maximum of 12.1 V at its rated peak pulse current of 49.6 A (10/1000 μs waveform). This VC value defines the upper voltage limit imposed on protected circuitry during worst-case transients, enabling safe operation of 5 V-tolerant ICs and preventing overvoltage damage to downstream components.
Does P6KE8.2CAHE3/54 have any safety certifications?
Yes, P6KE8.2CAHE3/54 carries Underwriters Laboratories (UL) recognition under file E136766 for both unidirectional and bidirectional configurations, complying with UL 497B for secondary circuit protectors. It also meets RoHS Directive 2011/65/EU (HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance).
