MZ0912B100Y,114

Overview

The MZ0912B100Y is an NPN silicon planar epitaxial microwave power transistor manufactured by Philips Semiconductors. It operates in a common base configuration and is specified for Class C operation. The device utilizes a SOT443A metal ceramic flange package with the base connected to the flange. Key electrical parameters include a collector-base voltage of -65 V, a collector-emitter voltage of -60 V, and a maximum total power dissipation of 290 W under pulsed conditions (tp = 10 μs; δ = 10%). Microwave performance at Tmb ≤ 25 °C yields output power greater than 100 W, gain exceeding 7 dB, and collector efficiency above 42% across the 0.960 to 1.215 GHz frequency range.

Feature Summary

• Interdigitated structure provides high emitter efficiency
• Diffused emitter ballasting resistors provide excellent current sharing and withstand high VSWR
• Gold metallization ensures stable characteristics and excellent lifetime
• Multicell geometry improves power sharing and reduces thermal resistance

Applications

• Common base class-C broadband pulse power amplifiers operating at 960 to 1215 MHz for TACAN application

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm that the BeO slab remains undamaged during handling, as the product contains beryllium oxide which requires specific disposal protocols according to local chemical waste regulations. Ensure proper mounting torque and thermal interface compliance to maintain specified junction temperatures.

Selection Notes

Select this component for designs requiring high-efficiency microwave power amplification in the UHF band. Verify compatibility with the SOT443A package dimensions and mounting requirements. Ensure the circuit design supports common base topology and Class C biasing. Evaluate thermal management capabilities against the specified thermal resistance values to prevent junction temperature exceedance during pulsed operation.

Part Context

The MZ0912B100Y belongs to a family of NPN microwave power transistors produced by Philips Semiconductors, alongside the MX0912B100Y variant. While both share similar electrical characteristics and applications, the MZ0912B100Y specifically features the SOT443A package with the base connected to the flange, distinguishing it from the MX0912B100Y which uses the SOT439A package.
