BC558BRL1

Single Bipolar Transistors Overview

The BC558BRL1 is a PNP silicon amplifier transistor manufactured by onsemi, housed in a TO-92 (Case 29) package. It features a maximum collector-emitter voltage of -30 Vdc and continuous collector current of -100 mAdc. The device supports an operating junction temperature range from -55°C to +150°C with total device dissipation rated at 625 mW at 25°C ambient. Electrical characteristics include a DC current gain (hFE) minimum of 120 for the B series at -10 mAdc, and a current-gain bandwidth product (fT) typical value of 360 MHz.

Single Bipolar Transistors Feature Summary

• PNP epitaxial silicon planar design optimized for amplifier applications
• Lead-free packaging available compliant with environmental directives
• High current-gain bandwidth product suitable for small-signal amplification

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Small-signal processing stages
• Switching applications within specified voltage limits

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1 corresponds to the Tape & Reel shipping configuration containing 2000 units per reel as documented in the official onsemi Device Ordering Information table. Confirm that the part number includes the correct series designation (B) for the required DC current gain specifications. Ensure compatibility with TO-92 through-hole mounting requirements.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -30 V collector-emitter rating and -100 mA continuous current capacity is required. The B series provides a guaranteed minimum hFE of 120 at -10 mAdc. Consider the thermal resistance of 200°C/W junction-to-ambient for heat dissipation planning in ambient conditions above 25°C.

Single Bipolar Transistors Part Context

This device belongs to the BC55x family of PNP silicon transistors, which includes complementary NPN devices such as the BC547 and BC548. The BC558 variant specifically offers a -30 V breakdown voltage, distinguishing it from higher-voltage counterparts like the BC556 (-65 V). The RL1 suffix indicates a specific bulk packaging format distinct from bulk or ammo box options.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC558BRL and BC558BZL1 from onsemi, which share identical electrical ratings and pin configurations but differ in shipping packaging.
