Additional Details:

The UDZV9.1B is typically available in a small surface-mount package, such as a SOD-323 or similar. It's crucial to consult the Rohm Semiconductor datasheet for the UDZV9.1B for precise electrical characteristics, thermal resistance, maximum ratings (power dissipation, forward current, reverse voltage), and package dimensions before using it in a design. The datasheet will also specify the test conditions under which the Zener voltage is measured. Careful attention to these parameters ensures reliable and safe operation of the diode within its specified limits.
