onsemi MPS6562_D74Z

Overview

MPS6562_D74Z from Fairchild Semiconductor is a PNP general-purpose bipolar junction transistor (BJT) designed for amplification and switching applications up to 500 mA collector current. It features V_CEO = 25 V, h_FE = 35–200 (at I_C = 10–500 mA), f_T = 60 MHz, and TO-92 package with emitter-first radial ammo packaging (EOL code D74Z). It is used in low-voltage DC-DC converter bias circuits and discrete logic-level switching.

For engineers reviewing the MPS6562_D74Z datasheet, pinout, applications, or equivalent options, key selection considerations include its PNP polarity, 25 V breakdown rating, 625 mW power dissipation, TO-92 mechanical compatibility, and verified performance at I_C = 500 mA with V_CE(sat) ≤ 0.5 V.

Technical Context

The MPS6562_D74Z implements a silicon planar epitaxial PNP BJT structure optimized for linear amplification and saturated switching. Its DC current gain (h_FE) varies from 35 at I_C = 10 mA to 50 at I_C = 500 mA, supporting stable biasing across load ranges. The device exhibits f_T = 60 MHz under standard test conditions (I_C = 10 mA, V_CE = 10 V), confirming usable RF capability in low-frequency signal paths.

Thermal design relies on R_θJA = 200 °C/W and R_θJC = 83.3 °C/W, with maximum junction temperature rated at +150 °C. Absolute maximum ratings include V_CBO = 25 V, V_EBO = 5.0 V, and continuous I_C = 1.0 A - though operational use is specified to 500 mA per design intent and TN4033A process documentation.

FAQ

What is the pin configuration of the MPS6562_D74Z in its TO-92 radial ammo package?

The MPS6562_D74Z uses TO-92 package with emitter-first radial ammo orientation (EOL code D74Z), where the flat side faces upward and the collector lead is first. Pin order, viewing from bottom (lead side), is Collector–Base–Emitter. This matches Figure 3.0 "Configuration M" in the official Fairchild TO-92 Tape and Reel Data document.

Does the MPS6562_D74Z support continuous 500 mA collector current operation?

Yes - the MPS6562_D74Z is rated for I_C = 500 mA in switching applications per its design specification and electrical characteristics table. At this current, V_CE(sat) ≤ 0.5 V and h_FE ≥ 50 are guaranteed, provided junction temperature remains within −55°C to +150°C and power dissipation stays within derated limits.

What is the maximum operating frequency for small-signal amplification using the MPS6562_D74Z?

The MPS6562_D74Z has an f_T of 60 MHz, measured at I_C = 10 mA and V_CE = 10 V. For small-signal amplification, usable bandwidth extends to ~10 MHz with stable gain; beyond that, phase shift and attenuation increase. It is not intended for RF front-end or GHz-range applications.

Can the MPS6562_D74Z replace the PN2907 in existing designs?

The MPS6562_D74Z shares similar V_CEO, h_FE, and TO-92 packaging with the PN2907, but exhibits higher f_T (60 MHz vs. ~10 MHz) and tighter V_CE(sat) spec (≤0.5 V vs. ≤0.7 V). It is a functional upgrade in most linear and switching roles, though validation of thermal margin and bias network stability is recommended before drop-in replacement.

Is the MPS6562_D74Z compliant with RoHS and lead-free soldering requirements?

The MPS6562_D74Z was manufactured under Fairchild's pre-2016 specifications and is not inherently RoHS-compliant. Its lead finish is SnPb (tin-lead); Pb-free alternatives such as the FMMT618 (SOT-23) or NSS6512 (SOT-23) should be selected for RoHS-constrained designs. Always verify compliance status via ON Semiconductor's current product documentation.
