Product details

Overview

2SC536F-SPA-AC from onsemi is an NPN bipolar junction transistor in TO-92 (SC-43A) package, rated for 50 V V_CEO, 150 mA I_C, and 500 mW P_C, with low V_CE(sat) of –0.3 V at I_C = 100 mA / I_B = 10 mA. It delivers h_FE of 160–320 (Rank F), f_T = 200 MHz, and is used in audio preamplifier stages and low-power switching circuits.

For engineers reviewing the 2SC536F-SPA-AC datasheet, pinout, applications, or equivalent options, key selection criteria include verified h_FE binning (F-rank), guaranteed V_CE(sat) performance at 100 mA, TO-92 mechanical compatibility, and validated operation up to 200 MHz f_T.

Technical Context

The 2SC536F-SPA-AC operates as a general-purpose NPN amplifier/switch with fixed-emitter bias topology. Its design supports DC-coupled small-signal amplification and pulse switching up to 200 MHz, enabled by low Cob (3.0 pF at V_CB = –6 V) and high ASO margin.

It shares the same die and package platform as the complementary PNP 2SA608N, enabling matched-pair use in push-pull configurations. Absolute maximum ratings are defined at T_a = 25°C, with derated power dissipation (P_C) down to 0 mW at T_a ≥ 150°C per the PC–Ta curve.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage under open-base conditions; defines upper rail limit in switching designs.
I_C	150 mA - Continuous collector current rating; supports load switching up to ~100 mA with thermal margin.
V_CE(sat)	–0.3 V at I_C/I_B = 100 mA/10 mA - Confirmed low saturation voltage enables <100 mW switch loss at rated current.
h_FE	160–320 (Rank F) - Guaranteed DC current gain range ensures predictable base drive requirements in linear and saturated modes.
f_T	200 MHz - Unity-gain frequency confirms usable bandwidth for RF preamp and HF oscillator applications up to ~50 MHz.
C_ob	3.0 pF at V_CB = –6 V - Low output capacitance minimizes Miller effect in common-emitter amplifiers.
P_C	500 mW - Total package power dissipation at T_a = 25°C; requires heatsinking or derating above 50°C ambient.

Pinout & Package

2SC536F-SPA-AC uses the TO-92 (SC-43A) through-hole package with standard NPA-WA outline: 4.5 mm height, 3.7 mm width, 3.5 mm depth, 0.19 g mass. Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-impedance return path; polarity defines NPN operation.
2 (Collector)	Current source terminal	Drives load toward positive supply; voltage swing limited by V_CEO = 50 V.
3 (Base)	Control input	Receives forward-biased current to enable conduction; requires I_B ≥ I_C/h_FE(min) for saturation.

Key Features

Feature	Design Value
Low V_CE(sat)	–0.3 V at 100 mA ensures <30 mW conduction loss in switching applications.
High f_T	200 MHz enables stable small-signal amplification up to VHF band without external compensation.
Wide ASO	Validated safe operating area supports pulsed I_CP = 400 mA (100 ms) without secondary breakdown.
F-rank h_FE binning	160–320 gain range allows consistent biasing across production lots without recalibration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC536NF-NPA-AT	Same die, identical electrical specs, but packaged in SC-43A with Pb-free finish and different marking (C536 + lot/rank).	No functional difference; fully interchangeable in all 2SC536F-SPA-AC use cases including audio, switching, and RF.	Select when RoHS compliance and traceable lot marking are required; no layout or schematic change needed.
MPSA18	Higher V_CEO (50 V vs. 45 V), lower h_FE (100–300), same TO-92 package; f_T = 300 MHz but Cob = 4.0 pF.	Preferred in higher-voltage analog switches; less suitable for low-V_CE(sat) critical designs due to typical V_CE(sat) > –0.4 V.	Choose for extended bandwidth where gain consistency is secondary; verify V_CE(sat) meets system loss budget.

Compared with 2SC536NF-NPA-AT, the 2SC536F-SPA-AC offers identical performance with legacy marking and plating; versus MPSA18, it trades 100 MHz f_T headroom for tighter h_FE control and lower saturation voltage-critical in battery-sensitive linear applications.

FAQ

What is the pin configuration of the 2SC536F-SPA-AC?

The 2SC536F-SPA-AC uses a standard TO-92 (SC-43A) package with Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base, as confirmed in the official onsemi package drawing EN6324B. This configuration is consistent across all 2SC536x variants and matches industry-standard NPN orientation for through-hole assembly.

Does the 2SC536F-SPA-AC have Pb-free construction?

No-the 2SC536F-SPA-AC uses legacy leaded plating per its "SPA-AC" suffix and original manufacturing documentation. For Pb-free alternatives, consider the 2SC536NF-NPA-AT, which carries the same die and electrical specs but complies with RoHS Directive 2011/65/EU.

What is the guaranteed h_FE range for the 2SC536F-SPA-AC?

The 2SC536F-SPA-AC is Rank F, with a guaranteed DC current gain (h_FE) of 160 to 320 at V_CE = 6 V and I_C = 1 mA. This binning is explicitly documented in the onsemi datasheet No. 6324, ensuring predictable base drive requirements in production designs using the 2SC536F-SPA-AC.

Can the 2SC536F-SPA-AC replace the 2SC536NG-NPA-AT in existing designs?

Yes-the 2SC536F-SPA-AC and 2SC536NG-NPA-AT share identical absolute maximum ratings, electrical characteristics, and TO-92 packaging. The only differences are marking format and plating; both meet the same 2SC536N specification, making them functionally interchangeable in any circuit using the 2SC536F-SPA-AC.

What is the maximum operating temperature for the 2SC536F-SPA-AC?

The 2SC536F-SPA-AC has a maximum junction temperature (T_j) of 150°C and storage temperature range of –55°C to +150°C. Its power dissipation must be derated linearly above 25°C ambient, reaching zero at 150°C, as shown in the PC–Ta curve (IT00510) in the official 2SC536N datasheet.
