onsemi BDV64BG

Overview

BDV64BG from onsemi is a PNP complementary silicon plastic power Darlington transistor designed for high-current output stages in general-purpose amplifier circuits. It delivers 10 A continuous collector current, sustains 100 V collector-emitter voltage, and achieves minimum DC current gain (h_FE) of 1000 at 5 A, enabling efficient switching and linear amplification in audio and industrial power stages.

For engineers reviewing the BDV64BG datasheet, pinout, applications, or equivalent options, key selection criteria include its TO-247 package thermal resistance (1.0 °C/W), built-in base-emitter shunt resistors, Pb-free compliance, and safe operating area defined up to 150 °C junction temperature.

Technical Context

The BDV64BG is a monolithic PNP Darlington pair with integrated base-emitter shunt resistors, eliminating external bias network requirements. Its architecture supports high-current linear operation with V_CE(sat) ≤ 2.0 V at I_C = 5 A and I_B = 0.02 A, and V_BE(on) ≤ 2.5 V under same conditions.

It operates across −65 °C to +150 °C junction temperature range and features thermal-limited SOA governed by R_θJC = 1.0 °C/W, with secondary breakdown constraints validated for pulse durations down to 100 μs at T_J(pk) = 150 °C.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous collector current rating for BDV64BG?

The BDV64BG is rated for 10 A continuous collector current at case temperature T_C = 25 °C. This rating decreases linearly at 1.0 W/°C above 25 °C, consistent with its 125 W total device dissipation limit and 1.0 °C/W junction-to-case thermal resistance. Derating must be applied for operation above ambient or with limited heatsinking.

Does BDV64BG have built-in base-emitter resistors?

Yes, BDV64BG features monolithic construction with built-in base-emitter shunt resistors. This design eliminates the need for external pull-down resistors, ensuring reliable turn-off and preventing false triggering from leakage current or noise-critical for stable operation in high-gain amplifier output stages.

What package type is used for BDV64BG?

BDV64BG uses the TO-247 (Case 340L) package, a 4-lead through-hole plastic power package with pins 1 (Base), 2 and 4 (Collector), and 3 (Emitter). It is Pb-free and optimized for high thermal conductivity and mechanical robustness in industrial power applications.

Is BDV64BG suitable for audio amplifier output stages?

Yes, BDV64BG is specifically designed for use as an output device in complementary general-purpose amplifier applications. Its high h_FE (≥1000), low V_CE(sat) (≤2.0 V), and 100 V V_CEO make it well-suited for Class AB audio output stages delivering high current into low-impedance loads while maintaining linearity and thermal stability.

What is the safe operating area (SOA) limitation for BDV64BG at 100 μs pulse width?

At 100 μs pulse width, BDV64BG's SOA is limited by secondary breakdown, allowing up to 30 A at 20 V or 10 A at 100 V under T_J(pk) = 150 °C conditions. These limits are defined in Figure 6 of the official datasheet and require strict adherence to pulse duty cycle and thermal management to avoid irreversible failure.
