onsemi PN200A_D26Z

Overview

PN200A_D26Z from Fairchild Semiconductor is a PNP general-purpose amplifier transistor in TO-92 package, rated for V_CEO = 45 V, I_C = 500 mA continuous, and h_FE = 100–300 at I_C = 10–100 mA. It delivers V_CE(sat) ≤ 0.2 V at I_C = 10 mA / I_B = 1 mA and f_T = 250 MHz, enabling use in low-voltage audio preamplifier stages and discrete switching circuits.

For engineers reviewing the PN200A_D26Z datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal derating curves, TO-92 mechanical orientation (flat side down, emitter first), and validated alternatives for discrete PNP amplifier replacement in industrial control signal conditioning and legacy analog board repair.

Technical Context

The PN200A_D26Z implements a silicon planar PNP bipolar junction transistor structure optimized for linear amplification and moderate-speed switching. Its Process 68 fabrication ensures consistent h_FE distribution and low noise figure (NF = 4.0 dB at I_C = 100 µA), with guaranteed breakdown voltages including BVCBO = 60 V and BVCEO = 45 V under specified test conditions.

Thermal performance is defined by R_θJA = 357 °C/W on FR-4 PCB (1.6" × 1.6"), enabling operation up to +125 °C ambient when derated per 2.8 mW/°C above 25 °C. The device exhibits predictable saturation behavior (V_BE(sat) = 0.85 V at I_C = 10 mA) and stable small-signal gain across –40 °C to +125 °C junction temperature range.

FAQ

What is the pin configuration of PN200A_D26Z in TO-92 package?

The PN200A_D26Z uses standard TO-92 pinout: when viewing the flat side of the package with leads pointing downward, the left-to-right terminal order is Collector (C), Base (B), Emitter (E). This matches JEDEC TO-92 configuration and is confirmed by Fairchild's packaging documentation for EOL code D26Z.

Does PN200A_D26Z support operation at elevated temperatures?

Yes, PN200A_D26Z is rated for junction temperatures from –55 °C to +150 °C. Its thermal resistance R_θJA = 357 °C/W on FR-4 allows operation up to +125 °C ambient when derated at 2.8 mW/°C above 25 °C, making it suitable for under-hood automotive and industrial motor-drive applications.

How does PN200A_D26Z differ from PN200 in terms of DC current gain?

PN200A_D26Z guarantees h_FE ≥ 100 at I_C = 10 mA and ≥ 200 at I_C = 100 mA, whereas PN200 specifies h_FE ≥ 80 at I_C = 100 mA. This higher and tighter gain spread in PN200A_D26Z improves bias stability in precision amplifier designs without requiring gain-bin selection.

Is PN200A_D26Z compatible with automated SMT placement equipment?

No - PN200A_D26Z is packaged in TO-92 (through-hole) format with EOL code D26Z for tape-and-reel handling in axial component feeders. It is not compatible with standard SMT pick-and-place systems; for surface-mount use, consider the functionally equivalent MMBT200A in SOT-23 package.

What is the maximum safe collector current for continuous DC operation of PN200A_D26Z?

The absolute maximum continuous collector current for PN200A_D26Z is 500 mA, as specified in its Absolute Maximum Ratings table. However, practical design limits are governed by thermal derating: at 25 °C ambient, maximum dissipation is 350 mW, dropping to ~175 mW at 85 °C ambient due to the 2.8 mW/°C derating slope.
