Key Parameters

Substitute Part Grouping Explanation

Substitution of the L35L15VCB2 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage Rating: Reverse standoff voltage of 15V (Max) and breakdown voltage minimum of 16.7V
• Clamping Performance: Maximum clamping voltage of 36.8V at peak pulse current
• Current Handling: Peak pulse current of 9.5A (8/20µs) and peak pulse power of 350W
• Capacitance: 0.6pF @ 1MHz for signal integrity in high-speed applications
• Temperature Range: Operating range of -55°C to 125°C (TJ)
• Package: Surface mount SOD-323 (SC-76) form factor
• Channel Configuration: Single bidirectional channel

The DBLC15CI-7 meets all these parameters identically, establishing it as a direct functional equivalent.
