Product details

Overview

MPSL01_D26Z from Fairchild Semiconductor is an NPN general-purpose amplifier transistor in TO-92 package, rated for 120 V_CEO, 200 mA continuous collector current, and 625 mW total dissipation at 25°C. It is designed for high-voltage amplification and gas discharge display driving applications, with DC current gain (h_FE) ranging from 50 to 300 at V_CE = 5.0 V and I_C = 10 mA.

For engineers reviewing the MPSL01_D26Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 140 V_CBO rating, 8.0 pF output capacitance at 10 V, 60 MHz f_T, low V_CE(sat) of 0.2 V (I_C = 10 mA, I_B = 1.0 mA), and TO-92 tape-and-reel packaging with EOL code D26Z.

Technical Context

The MPSL01_D26Z implements a silicon planar NPN bipolar junction transistor structure optimized for linear amplification and switching in medium-voltage, moderate-current circuits. Its 150°C maximum junction temperature and 200°C/W junction-to-ambient thermal resistance support operation in compact, non-heatsinked designs.

It features a 60 MHz current-gain bandwidth product and small-signal h_fe ≥ 30 at 1 kHz, confirming suitability for audio-frequency amplification and pulse-driven display segment drivers. The device shares Process 16 fabrication with the 2N5551 and exhibits matching breakdown and leakage characteristics per specification table.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	120 V - supports operation in high-side switch or amplifier stages up to 120 V supply rails
I_C (continuous)	200 mA - enables direct drive of small relays, LED arrays, or gas discharge segments without external buffering
P_D @ 25°C	625 mW - defines maximum power handling before thermal derating begins at 5.0 mW/°C above ambient
h_FE	50–300 - provides stable DC biasing across production lots for Class-A amplifiers or saturated switches
f_T	60 MHz - ensures usable gain in audio and low-speed digital signal conditioning up to ~10 MHz
C_ob	8.0 pF @ 10 V - minimizes Miller effect in common-emitter configurations at frequencies below 10 MHz

Pinout & Package

Package: TO-92, straight lead configuration, no lead clip, epoxy molded plastic case with flat side indicating emitter-collector orientation. Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed with flat side facing user, leads down).

Pin/Terminal	Circuit Role	Design Meaning
Emitter (Pin 1)	Current sink terminal	Reference node for base-emitter biasing; connects to ground or low-impedance return path in common-emitter topology
Base (Pin 2)	Control input	Accepts current-limited drive (e.g., via 10 kΩ resistor) to achieve saturation or linear operation
Collector (Pin 3)	Current source terminal	Connects to load (e.g., display segment anode or relay coil) and high-voltage rail; carries full output current

Key Features

Feature	Design Value
High V_CBO	140 V - allows safe operation with collector-base reverse bias up to 140 V, critical for flyback energy recovery
Low V_CE(sat)	0.2 V @ 10 mA/1 mA - reduces conduction loss and self-heating in switching applications
Wide h_FE range	50–300 - accommodates production spread while maintaining functional margin in bias networks
TO-92 tape-and-reel	EOL code D26Z - supports automated SMT placement with 2,000 units per reel and standardized carrier tape dimensions

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2N5551	Identical Process 16 fabrication; same V_CEO/V_CBO/I_C ratings and h_FE range; minor variation in R_θJA (200 vs. 190°C/W)	No functional difference in display driving or amplification; identical pinout and thermal profile	Select 2N5551 when standard industry reference is required or for cross-manufacturer BOM consolidation
MPSA42	Higher V_CEO (300 V) and lower h_FE (min 40); same TO-92 package but different internal die design	Better suited for >200 V applications (e.g., CRT anode supplies); less optimal for low-gain linear stages due to tighter h_FE spread	Choose MPSA42 only when absolute breakdown margin exceeds 120 V; not drop-in for MPSL01_D26Z in existing 120 V designs

Compared with 2N5551 and MPSA42, the MPSL01_D26Z offers identical electrical performance to 2N5551 in high-voltage switching and amplification, while MPSA42 trades gain consistency for higher voltage capability-making MPSL01_D26Z the preferred choice for cost-sensitive, 120 V-class display and interface applications requiring proven process stability.

FAQ

What is the pin configuration of the MPSL01_D26Z?

The MPSL01_D26Z uses a standard TO-92 package with three leads: Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector. When viewing the flat side of the package with leads pointing downward, the leftmost pin is Emitter, center is Base, and rightmost is Collector. This configuration matches JEDEC TO-92 outline and is confirmed in Fairchild's packaging documentation for EOL code D26Z.

Does the MPSL01_D26Z support surface-mount assembly?

Yes, the MPSL01_D26Z is supplied in tape-and-reel format (EOL code D26Z) with carrier tape compliant to EIA-481 standards, enabling automated pick-and-place assembly. Each reel contains 2,000 units, and the TO-92 body dimensions-including lead pitch, clinch height, and tape width-are fully specified in Fairchild's TO-92 Tape and Reel Data document Rev. B1.

What is the maximum operating temperature for the MPSL01_D26Z?

The MPSL01_D26Z has a specified operating junction temperature range of –55°C to +150°C. Its thermal resistance is R_θJA = 200°C/W, meaning that at 25°C ambient and 625 mW dissipation, junction temperature rises to 150°C-the absolute maximum. Derating is required above 25°C at 5.0 mW/°C, as documented in the Absolute Maximum Ratings table.

How does the MPSL01_D26Z compare to the 2N5551 in terms of electrical performance?

The MPSL01_D26Z and 2N5551 share identical Process 16 fabrication, resulting in matched V_CEO (120 V), V_CBO (140 V), I_C (200 mA), h_FE (50–300), and f_T (60 MHz) specifications. Fairchild explicitly references the 2N5551 for characteristics, confirming functional equivalence. Both use TO-92 packaging and exhibit nearly identical thermal resistance values.

Is the MPSL01_D26Z suitable for use in life support devices?

No. Fairchild's Life Support Policy explicitly states that MPSL01_D26Z-and all products in this family-are not authorized for use as critical components in life support devices or systems without express written approval. The device lacks the qualification, traceability, and reliability assurance required for surgical implants, sustained life support, or safety-critical failure modes.
