Product details
Overview
2N5400_D27Z from Fairchild Semiconductor is a PNP bipolar junction transistor designed for general-purpose amplification and switching in high-voltage circuits, with VCEO = 120 V, IC = 600 mA, and hFE = 30–180 at IC = 1–50 mA. It operates across –55°C to +150°C and is commonly used in relay drivers, voltage-level shifters, and discrete logic interfaces.
For engineers reviewing the 2N5400_D27Z datasheet, pinout, applications, or equivalent options, key selection criteria include its TO-92 package configuration, emitter-first tape-and-reel orientation (Style E), guaranteed V(BR)CEO ≥ 120 V, fT up to 400 MHz, and thermal resistance RθJA = 200°C/W.
Technical Context
The 2N5400_D27Z is a silicon PNP BJT optimized for linear amplification and saturated switching in low-to-medium power analog and digital systems. Its design supports operation under high collector-emitter blocking voltage while maintaining stable DC current gain across temperature and bias conditions.
It features low saturation voltages (VCE(sat) ≤ 0.5 V at IC = 50 mA), moderate output capacitance (Cob = 6.0 pF), and noise figure of 8.0 dB in audio-band applications - enabling use in signal conditioning stages where voltage headroom and gain stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 120 V - Maximum safe collector-emitter voltage before breakdown; enables use in 100 V rail systems with margin. |
| IC | 600 mA - Continuous collector current rating; supports medium-power switching loads like small relays or LED arrays. |
| hFE | 30–180 - DC current gain range at VCE = 5 V; allows predictable base drive sizing across production lots. |
| fT | 100–400 MHz - Current gain–bandwidth product; supports RF preamp or broadband amplifier use up to ~100 MHz. |
| RθJA | 200 °C/W - Junction-to-ambient thermal resistance in free-air; defines maximum power dissipation without heatsinking. |
| VBE(sat) | 1.0 V - Base-emitter saturation voltage at IC/IB = 10; simplifies TTL/CMOS interface logic level translation. |
| PD | 625 mW - Total device dissipation at 25°C; derates linearly at 5.0 mW/°C above ambient. |
Pinout & Package
2N5400_D27Z is supplied in the standard TO-92 plastic package with lead configuration matching Fairchild's Style E tape-and-reel orientation: emitter is first wire off, flat side faces down, adhesive tape on top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current sink terminal | First pin in tape feed direction; connects to ground or low-side reference in common-emitter switches. |
| Base (B) | Control input | Modulates collector current; requires current-limited drive due to β-dependent gain. |
| Collector (C) | Current source terminal | Connected to positive supply or load; handles full switched current with 120 V standoff capability. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | 120 V enables direct replacement of older PNP transistors in legacy 100 V industrial control circuits. |
| Wide operating temperature | –55°C to +150°C junction range supports deployment in automotive engine compartments and outdoor telecom enclosures. |
| Low noise figure | 8.0 dB at audio frequencies makes it suitable for microphone preamplifier stages where SNR matters. |
| Controlled saturation behavior | VCE(sat) ≤ 0.5 V at IC = 50 mA ensures minimal conduction loss in discrete switch applications. |
| TO-92 tape-and-reel compatibility | E-style (D27Z) orientation guarantees consistent automated placement with emitter-first indexing in SMT assembly lines. |
Applications
| Relay Driver Circuit | Level-Shifting Interface |
|---|---|
Use Scenario: Driving 12 V/24 V electromagnetic relays from microcontroller GPIO pins. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter mode, sinking relay coil current to ground when base is pulled low. Use Value: High VCEO prevents breakdown during relay coil flyback transients; low VCE(sat) minimizes power loss and heat rise in compact PCB layouts. |
Use Scenario: Translating 3.3 V logic outputs to 5 V or 12 V domains in mixed-supply systems. IC Role / Device Role / Timing Role: Active-low level shifter using emitter-follower or common-emitter inversion topology. Use Value: Predictable hFE range allows accurate base resistor calculation; VBE(sat) = 1.0 V ensures clean logic thresholds across temperature. |
| Analog Signal Amplifier | Discrete Logic Inverter |
Use Scenario: Low-noise preamplification of sensor signals (e.g., thermocouple, photodiode) before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter amplifier stage with emitter degeneration for linearity and bandwidth control. Use Value: 8.0 dB noise figure preserves weak signal integrity; fT > 100 MHz supports wideband response up to audio and sub-RF frequencies. |
Use Scenario: Building non-inverting or inverting logic gates in repair or prototyping scenarios where ICs are unavailable. IC Role / Device Role / Timing Role: Saturated switch implementing NOT or NAND function with pull-up resistors. Use Value: Fast turn-off due to low Cob (6.0 pF) enables reliable operation up to 1–2 MHz clock rates in discrete logic designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA92 | VCEO = 300 V, hFE = 25–200, TO-92 package, same pinout (E-B-C). | Higher voltage rating suits flyback snubbers and CRT deflection circuits beyond 2N5400_D27Z scope. | Select MPSA92 when >120 V blocking is required; verify layout compatibility with identical footprint. |
| BC557 | VCEO = 45 V, IC = 100 mA, hFE = 110–800, TO-92 package, pinout E-B-C but lower power rating. | Optimized for low-current signal amplification, not medium-power switching. | Choose BC557 only for low-power, high-gain analog stages; avoid in relay or lamp driver roles. |
Compared with MPSA92 and BC557, the 2N5400_D27Z offers balanced performance between voltage capability and current handling - making it ideal for industrial control interfaces where 120 V standoff and 600 mA drive coexist, unlike the ultra-high-voltage or ultra-high-gain extremes of the alternatives.

FAQ
What is the pinout configuration of the 2N5400_D27Z?
The 2N5400_D27Z uses the standard TO-92 package with E-B-C (Emitter-Base-Collector) pin order when viewed with the flat side facing you and leads pointing downward. As a D27Z tape-and-reel variant, it follows Style E orientation: emitter is the first pin fed into the pick-and-place machine, flat side down, adhesive tape on top.
Is the 2N5400_D27Z RoHS compliant?
The 2N5400_D27Z was manufactured prior to full RoHS enforcement and does not carry formal RoHS certification. It contains leaded solder terminations per original Fairchild specifications. For new designs requiring compliance, consult Aetrix Electronics for qualified drop-in alternatives or re-engineered variants.
Can the 2N5400_D27Z replace the 2N5401 in a circuit?
No - the 2N5400_D27Z and 2N5401 are complementary PNP transistors with different voltage ratings: 2N5400_D27Z has VCEO = 120 V, while 2N5401 specifies VCEO = 150 V. Substitution may compromise reliability in circuits operating near 150 V; always verify voltage margin and hFE matching before interchanging.
What is the maximum power dissipation of the 2N5400_D27Z at 75°C ambient?
At 75°C ambient, the 2N5400_D27Z derates from its 625 mW maximum at 25°C by 5.0 mW/°C. The allowable power is 625 mW − (50°C × 5.0 mW/°C) = 375 mW. This assumes no heatsink; actual dissipation must remain below this value to keep junction temperature ≤150°C.
Does the 2N5400_D27Z support high-frequency switching?
The 2N5400_D27Z has an fT of 100–400 MHz, indicating usable gain up to ~100 MHz in small-signal amplification. However, its switching speed is limited by minority-carrier storage time; it is not recommended for >1 MHz hard-switching applications. Use dedicated RF or fast-switching transistors for such roles.
