Product details

Overview

2SC536E-SPA-AC from onsemi is an NPN bipolar junction transistor rated for 50 V V_CEO, 150 mA I_C, and 500 mW P_C, featuring low V_CE(sat) of –0.3 V at I_C = –100 mA / I_B = –10 mA, f_T = 200 MHz, and h_FE = 160–560 (rank-dependent). It is used in general-purpose amplification and switching circuits in consumer audio, power supply feedback, and signal conditioning stages.

For engineers reviewing the 2SC536E-SPA-AC datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE binning (Rank F/G), TO-92-compatible SC-43A package dimensions, and guaranteed f_T performance across temperature.

Technical Context

This NPN transistor operates in linear and saturated switching modes with a guaranteed minimum h_FE of 160 at I_C = 1 mA and V_CE = 6 V, and supports high-frequency small-signal amplification up to 200 MHz. Its low saturation voltage enables efficient current switching in discrete driver stages.

The device uses silicon planar epitaxial construction, exhibits a maximum junction temperature of 150°C, and maintains stable gain over –25°C to +75°C ambient per h_FE–I_C curves. Output capacitance is specified at 3.0 pF (typ) under V_CB = 6 V, supporting RF-critical bias networks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration.
I_C	150 mA - Continuous DC collector current rating defining usable load drive capability.
P_C	500 mW - Maximum power dissipation at T_a = 25°C; derates linearly above 25°C per PC–Ta curve.
f_T	200 MHz - Gain-bandwidth product confirming suitability for VHF amplification and oscillator design.
V_CE(sat)	–0.3 V - Confirmed saturation voltage at I_C/I_B = 10, enabling low-loss switching in discrete logic and driver circuits.
h_FE	160–560 - Rank-binned DC current gain range (F: 160–320, G: 280–560), critical for bias stability in amplifier designs.
C_ob	3.0 pF (typ) - Output capacitance at V_CB = 6 V, directly impacting high-frequency impedance matching and bandwidth limits.

Pinout & Package

2SC536E-SPA-AC is housed in the SC-43A package (equivalent to TO-92, TO-226AA, SOT-54), with standardized lead assignment and mechanical dimensions per outline drawing 7542-001. Mass: 0.19 g.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit terminal; connects to ground or low-impedance return path in common-emitter configurations.
2	Collector	Current entry terminal; interfaces with load or pull-up resistor; requires voltage margining per V_CEO rating.
3	Base	Control input; drives transistor into active/saturation via current-limited source (e.g., resistor from microcontroller GPIO).

Key Features

Feature	Design Value
Low V_CE(sat)	–0.3 V at I_C = –100 mA ensures minimal conduction loss and thermal rise in switching applications.
High f_T	200 MHz enables stable small-signal amplification up to VHF band without external compensation.
Wide ASO	Guaranteed Safe Operating Area supports pulsed I_CP = 400 mA (100 ms), extending reliability in transient-loaded circuits.
Rank-binned h_FE	F/G h_FE bins (160–560) allow precise bias network design and production yield optimization.
TO-92 compatible	SC-43A footprint enables drop-in replacement in legacy through-hole PCB layouts requiring manual or wave soldering.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC536NF-NPA-AT	Same die, identical electrical specs, but Rank F h_FE (160–320); Pb-free, same SC-43A package.	No functional difference; suitable for designs requiring tighter h_FE tolerance and RoHS compliance.	Select when h_FE consistency >320 is not required and Pb-free sourcing is mandated.
MPSA18	Higher V_CEO (50 V vs. 45 V), lower f_T (300 MHz vs. 200 MHz), same TO-92 package; h_FE = 100–300 (unbinned).	Preferred in higher-voltage analog switches; less suitable for precision gain-critical amplifiers due to unbinned h_FE.	Choose for cost-sensitive, non-critical gain applications where wider V_CEO margin is needed.

Compared with 2SC536E-SPA-AC, 2SC536NF-NPA-AT offers identical performance with RoHS compliance and narrower h_FE spread, while MPSA18 trades h_FE predictability for higher voltage headroom and broader availability-making it viable only where gain stability is secondary to voltage rating.
