DESCRIPTION

handbook, 4 columns	k	a
		MAM130

Marking code: P4.

Cathode side indicated by a white bar.

Fig.1 Simplified outline (SOD323) and symbol.

The BB134 is a variable capacitance diode, fabricated in planar technology, and encapsulated in the SOD323 very small plastic SMD package.

The excellent matching performance is achieved by a direct matching assembly procedure. The unmatched type, BB135 has the same specification.

ELECTRICAL CHARACTERISTICS

Tj = 25 °C; unless otherwise specified.
