This document is a datasheet for a series of transient voltage suppression (TVS) diodes manufactured by Protek Devices. Here's a breakdown of the key information:

1. Product Overview:

️· Type: TVS (Transient Voltage Suppression) diodes. These devices protect sensitive electronics from voltage spikes and surges.
️· Package: SO-8 (Small Outline 8-pin) package.
️· Applications: General purpose ESD protection, overvoltage protection, surge suppression in various electronics (communication, industrial, consumer, etc.).

2. Key Specifications (varies by specific part number within the series, but general information is provided):

️· Reverse Stand-off Voltage (Vr): The maximum continuous reverse voltage that can be applied to the device without breakdown. (Values will vary based on the specific model - e.g., 5V, 12V, 24V).
️· Breakdown Voltage (Vbr): The voltage at which the device begins to conduct significantly in the reverse direction.
️· Holding Current (Ih): The current at which the clamping voltage stabilizes.
️· Peak Pulse Current (Ipp): The maximum non-repetitive surge current the device can handle. (Crucial for surge protection capability).
️· Power Dissipation: How much power the device can dissipate without damage.
️· Operating Temperature Range: -55°C to +150°C

3. Electrical Characteristics (Tables provided for specific voltage/current ratings):

️· Detailed tables specify the Vr, Vbr, Ih, and Ipp for various models within the series.

️· Clamping Voltage (Vc): The maximum voltage the device will limit during a surge event. Lower clamping voltage is better for protecting sensitive components.

4. Graphs & Charts:

️· Pulse Waveform: Shows the typical surge waveform used for testing.
️· Current Derating Curve: Shows how the peak pulse current capability decreases as the operating temperature increases.
️· Clamping Voltage vs. Peak Pulse Current: Illustrates how the clamping voltage changes with the pulse current.
️· Reverse Leakage Current vs. Reverse Voltage: Shows leakage characteristics.

5. Package Information:
