Philips Semiconductors Product specification Voltage regulator diodes BZX79 series FEATURES
• Total power dissipation: max. 500 mW • Two tolerance series: ±2%, and approx. ±5% • Working voltage range: nom. 2.4 to 75 V (E24 range) • Non-repetitive peak reverse power dissipation: max. 40 W. handbook, halfpage
k a APPLICATIONS
MAM239 • Low voltage stabilizers or voltage references.
DESCRIPTION
Low-power voltage regulator diodes in hermetically sealed The diodes are type branded. leaded glass SOD27 (DO-35) packages. The diodes are available in the normalized E24 ±2% (BZX79-B) and Fig.1 Simplified outline (SOD27; DO-35) and approx. ±5% (BZX79-C) tolerance range. The series symbol. consists of 37 types with nominal working voltages from 2.4 to 75 V.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
