Product details

Overview

2SC536G-SPA-AC from onsemi is an NPN bipolar junction transistor in TO-92 (SC-43A/NPA-WA) 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, optimized for general-purpose amplification and switching in consumer audio and signal routing circuits.

For engineers reviewing the 2SC536G-SPA-AC datasheet, pinout, applications, or equivalent options, key selection criteria include its h_FE rank G (280–560 at V_CE = –6 V, I_C = –1 mA), f_T = 200 MHz, Cob = 3.0 pF at V_CB = –6 V, and guaranteed ASO performance up to 400 mA pulse current.

Technical Context

The 2SC536G-SPA-AC operates as a single NPN silicon BJT with fixed emitter-base-collector terminal assignment and no integrated biasing or protection circuitry. Its design supports linear amplification and saturated switching across low-to-high frequency ranges, enabled by high f_T and low output capacitance.

It features a wide Safe Operating Area (ASO) validated up to 400 mA pulsed collector current and 100 ms pulse width, with thermal derating defined by P_C = 500 mW at T_a = 25°C and linear reduction to zero at T_a = 150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition
I_C	150 mA - Continuous DC collector current rating defining steady-state switching/amplifier load capacity
V_CE(sat)	–0.3 V - Low saturation voltage ensures minimal power loss and heat generation in switching applications
h_FE (Rank G)	280–560 - Guaranteed DC current gain range at V_CE = –6 V, I_C = –1 mA, enabling predictable bias design
f_T	200 MHz - Gain-bandwidth product confirming usable RF performance up to VHF band in small-signal stages
C_ob	3.0 pF - Output capacitance at V_CB = –6 V, critical for high-frequency stability and impedance matching
P_C	500 mW - Maximum power dissipation at 25°C ambient, requiring thermal management above 75°C

Pinout & Package

2SC536G-SPA-AC uses the NPA-WA package (TO-92 variant, SC-43A), with standardized lead configuration: Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base. The package has a mass of 0.19 g and dimensions of 4.5 mm × 3.7 mm × 3.5 mm (L×W×H).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit path for NPN operation	Connected to ground or low-impedance return in common-emitter configurations; defines reference for V_BE and I_E
2 (Collector)	Current entry path under forward active/saturation	Drives load in switching mode; requires voltage margin above V_CEO rating to avoid avalanche
3 (Base)	Control terminal for minority-carrier injection	Requires current-limited drive (e.g., R_B) to achieve target I_C; sensitive to ESD due to thin oxide layer

Key Features

Feature	Design Value
Low V_CE(sat)	–0.3 V at I_C/I_B = 10 ensures efficient saturated switching with <0.5% conduction loss at 100 mA loads
High f_T	200 MHz enables stable small-signal amplification up to 50 MHz with ≥10 dB gain margin
Wide ASO	Rated for 400 mA pulsed I_C with 100 ms duty cycle, supporting transient surge handling in driver stages
Rank-G h_FE	280–560 spread allows consistent bias point selection without individual device binning in production
Pb-Free construction	Complies with RoHS Directive 2011/65/EU, eliminating lead contamination risk in reflow soldering and end-of-life recycling

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, Rank F h_FE (160–320); identical V_CEO, I_C, f_T, and package	Lower gain range reduces bias stability margin in high-precision amplifiers but lowers cost	Select when gain consistency is less critical than unit cost and standardization across BOM variants
MPSA18	Higher V_CEO (50 V vs. 45 V), same I_C (150 mA), lower f_T (150 MHz), different pinout (E-B-C vs. E-C-B)	Not pin-compatible; requires PCB layout change; better suited for higher-voltage logic interfacing	Choose only if redesigning layout and needing extended voltage margin with comparable gain and speed

Compared with 2SC536G-SPA-AC, the 2SC536NF-NPA-AT offers lower-cost gain binning without performance trade-offs in switching, while MPSA18 provides higher voltage headroom at the expense of pin compatibility and reduced RF capability-neither is a drop-in replacement without validation.

FAQ

What is the pin configuration of the 2SC536G-SPA-AC?

The 2SC536G-SPA-AC uses the NPA-WA (TO-92) package with Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base, as confirmed in the official onsemi outline drawing EN6324B. This E-C-B order differs from standard TO-92 E-B-C layouts, so PCB footprint must match the NPA-WA mechanical specification-not generic TO-92 templates. The 2SC536G-SPA-AC marking "C536" appears adjacent to Pin 1.

Does the 2SC536G-SPA-AC meet RoHS requirements?

Yes, the 2SC536G-SPA-AC is Pb-Free and complies with EU RoHS Directive 2011/65/EU, as stated in the onsemi ordering information table and package shipping memo. It uses matte tin lead finish and halogen-free molding compound, supporting lead-free reflow profiles up to 260°C peak. The 2SC536G-SPA-AC is not intended for medical implant or life-support systems per onsemi's standard disclaimer.

What is the maximum safe operating frequency for the 2SC536G-SPA-AC?

The 2SC536G-SPA-AC has a gain-bandwidth product (f_T) of 200 MHz, meaning it retains unity current gain up to that frequency under specified test conditions (V_CE = 6 V, I_C = 10 mA). For stable small-signal amplification, practical use is limited to ≤50 MHz to maintain ≥10 dB gain margin and phase stability. The 2SC536G-SPA-AC is not characterized for RF power applications beyond 100 MHz.

How does the "G" suffix in 2SC536G-SPA-AC affect its electrical behavior?

"G" denotes the h_FE rank bin: 2SC536G-SPA-AC guarantees DC current gain between 280 and 560 at V_CE = –6 V and I_C = –1 mA, whereas "F"-rank devices (e.g., 2SC536F) specify 160–320. This tighter high-gain bin improves bias point predictability in amplifier designs and reduces variation in switching threshold currents. All other parameters-including V_CEO, I_C, and f_T-are identical across ranks.

Can the 2SC536G-SPA-AC replace a 2N3904 in existing designs?

No, direct substitution is not recommended. While both are NPN TO-92 transistors, the 2SC536G-SPA-AC has E-C-B pinout versus 2N3904's E-B-C, risking reverse-bias damage if installed without footprint revision. Additionally, the 2SC536G-SPA-AC has higher f_T (200 MHz vs. 300 MHz) but lower V_CEO (50 V vs. 40 V) and different h_FE distribution. Any replacement requires full validation of bias network, thermal performance, and signal integrity for the 2SC536G-SPA-AC.
