onsemi MPS6534_D75Z

Overview

MPS6534_D75Z from Fairchild Semiconductor is a PNP general-purpose amplifier and switch in TO-92 package, rated for 40 V V_CEO, 800 mA continuous collector current, and 625 mW power dissipation at 25°C. It delivers DC current gain (h_FE) of 60–270 at IC = 10–500 mA and exhibits V_CE(sat) ≤ 0.3 V at IC = 100 mA/IB = 10 mA, supporting low-loss switching in discrete power control circuits.

For engineers reviewing the MPS6534_D75Z datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, TO-92 mechanical compatibility, thermal resistance (R_θJA = 200 °C/W), breakdown voltage margin, and saturation behavior under defined drive conditions.

Technical Context

The MPS6534_D75Z is fabricated on Fairchild's Process 63, optimized for general-purpose linear amplification and saturated-switching operation. Its design supports stable h_FE across IC = 10–500 mA with V_CE = 1.0–10 V, and it maintains V_(BR)CEO ≥ 40 V at IC = 10 mA with IB = 0.

Thermal performance is defined by R_θJC = 83.3 °C/W and R_θJA = 200 °C/W, enabling operation from –55°C to +150°C junction temperature. The device uses standard TO-92 leadframe geometry with emitter-first orientation per D75Z tape-and-reel specification.

Manufacturer

Fairchild Semiconductor was a U.S.-based semiconductor manufacturer specializing in power management, analog, and discrete components before its acquisition by ON Semiconductor in 2016.

The MPS6534_D75Z belongs to Fairchild's legacy PNP bipolar transistor product line, designed for cost-sensitive, medium-current amplification and switching in industrial controls, power supplies, and interface circuits.

FAQ

What is the pin configuration of the MPS6534_D75Z in TO-92 package?

The MPS6534_D75Z uses TO-92 package with collector as first wire off, flat side oriented upward, and adhesive tape applied to the top side. Pin 1 is emitter, Pin 2 is base, and Pin 3 is collector-verified per Fairchild's D75Z tape-and-reel specification and mechanical drawings.

Does the MPS6534_D75Z support pulsed operation beyond its continuous ratings?

Yes, the MPS6534_D75Z supports pulsed operation with pulse width ≤ 300 µs and duty cycle ≤ 2.0%, as specified in its small-signal characteristics section. However, thermal limits must still be observed, and junction temperature must remain ≤ 150°C during pulses-consult Fairchild's application notes for transient thermal modeling.

What is the typical V_BE(sat) for MPS6534_D75Z under rated switching conditions?

The MPS6534_D75Z exhibits V_BE(sat) = 1.0 V at IC = 100 mA and IB = 10 mA, per its ON CHARACTERISTICS table. This value is critical for calculating base resistor values in saturated-switch designs and remains stable across the –55°C to +150°C operating range.

Can MPS6534_D75Z replace MPS6515 in an existing design?

MPS6534_D75Z can replace MPS6515 only if the application operates below 30 V collector-emitter stress and does not rely on MPS6515's tighter h_FE spec at 150 mA. The MPS6534_D75Z offers higher voltage rating (40 V vs. 30 V) but wider h_FE spread-designers must verify base drive sufficiency and thermal margin.

Is the MPS6534_D75Z RoHS compliant and halogen-free?

The MPS6534_D75Z was manufactured prior to RoHS enforcement deadlines and is not certified RoHS-compliant or halogen-free. For new designs, ON Semiconductor's modern equivalents (e.g., NSS6534PFR) should be evaluated-contact Aetrix Electronics for compliance documentation and replacement guidance for MPS6534_D75Z.
