Product details

Overview

2SC536KE-BOSE-AA from ON Semiconductor 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 low-to-high-frequency amplifier and switching stages in consumer audio power stages.

For engineers reviewing the 2SC536KE-BOSE-AA datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE binning (F/G), TO-92-compatible NPA-WA package dimensions, and ASO-rated safe operating area for pulse-current reliability.

Technical Context

This NPN transistor operates with a V_BR_CEO of –50 V and V_BR_CBO of –60 V, supporting robust voltage margin in linear and saturated switching modes. Its f_T = 200 MHz and Cob = 3.0 pF at V_CB = –6 V enable stable high-frequency amplification up to VHF range.

The device uses silicon planar epitaxial construction with a wide SOA curve validated for I_CP = 400 mA pulses (100 ms), and thermal resistance R_θJA ≈ 250°C/W (derived from P_C = 500 mW at T_A = 25°C and T_j(max) = 150°C), suitable for ambient-limited discrete gain blocks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–50 V - Maximum collector-emitter voltage before breakdown; defines safe DC/peak swing headroom in amplifier output stages.
I_C	–150 mA - Continuous collector current rating; sets upper limit for steady-state bias and load drive capability.
V_CE(sat)	–0.3 V @ I_C/I_B = –100 mA/–10 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications.
f_T	200 MHz - Unity-gain frequency confirms usable bandwidth for RF preamp and oscillator buffer roles up to ~100 MHz.
h_FE	160–560 (F/G rank) - DC current gain range determines base drive requirements and small-signal transconductance stability.
C_ob	3.0 pF @ V_CB = –6 V - Output capacitance impacts high-frequency roll-off and stability in tuned amplifier designs.
P_C	500 mW - Maximum power dissipation at T_A = 25°C; requires thermal derating above 25°C per PC–Ta curve.

Pinout & Package

2SC536KE-BOSE-AA is housed in the NPA-WA package - a TO-92 variant (SC-43A / TO-226AA / SOT-54) with 0.19 g mass and standardized lead spacing. Dimensions: 4.5 mm length × 3.7 mm width × 4.0 mm height (max), 1.27 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink terminal; connects to ground or low-impedance return path in common-emitter configurations.
2	Collector	Current source terminal; ties to supply rail or load in active/saturated operation; primary heat path in TO-92.
3	Base	Control input; requires current-limited drive (e.g., via series resistor) to achieve target I_C based on h_FE.

Key Features

Feature	Design Value
Low V_CE(sat)	–0.3 V enables <100 mW conduction loss at 100 mA, improving efficiency in Class-A/B audio driver stages.
Wide ASO	Validated safe operating area supports 400 mA pulsed current (100 ms), critical for transient overload resilience in speaker protection circuits.
High f_T	200 MHz gain-bandwidth allows stable small-signal amplification up to VHF without external compensation.
Rank-binned h_FE	F (160–320) and G (280–560) variants ensure predictable DC biasing and matching in differential pairs.

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, F-rank h_FE (160–320), identical absolute max ratings and electrical specs; marked "C536" + lot/rank.	No functional difference; used interchangeably where h_FE lower bound ≥160 is acceptable.	Select when tighter h_FE consistency is required over full 160–560 range.
MPSA18	Higher V_CEO (–50 V same), but lower f_T (150 MHz), higher V_CE(sat) (–0.5 V), and wider h_FE spread (100–300).	Suitable for audio switching but less optimal for >50 MHz RF buffering due to reduced bandwidth and higher loss.	Choose for cost-sensitive legacy designs where 200 MHz f_T is not required.

Compared with 2SC536KE-BOSE-AA, 2SC536NF-NPA-AT offers identical performance with guaranteed h_FE lower bound, while MPSA18 trades bandwidth and saturation voltage for broader availability and lower cost in non-RF linear applications.

FAQ

What is the package type of the 2SC536KE-BOSE-AA?

The 2SC536KE-BOSE-AA uses the NPA-WA package - a TO-92 variant (also designated SC-43A, TO-226AA, or SOT-54) with standardized 1.27 mm lead pitch and 4.5 × 3.7 × 4.0 mm outline. This through-hole package supports manual or automated insertion and provides adequate thermal dissipation for its 500 mW rating.

Does the 2SC536KE-BOSE-AA have a specified h_FE rank?

Yes, the 2SC536KE-BOSE-AA is rank-binned: F-rank specifies h_FE = 160–320 and G-rank specifies h_FE = 280–560 at V_CE = –6 V and I_C = –1 mA. The marking "C536" on the device body identifies it as part of the 2SC536N series, with rank indicated separately in packaging documentation.

What is the maximum pulsed collector current for the 2SC536KE-BOSE-AA?

The 2SC536KE-BOSE-AA supports I_CP = –400 mA for pulse widths up to 100 ms, as confirmed by the ASO curve in the official datasheet (No.6324-5/6). This pulsed rating assumes duty cycle and ambient conditions that prevent junction temperature from exceeding 150°C.

Is the 2SC536KE-BOSE-AA RoHS compliant and lead-free?

Yes, the 2SC536KE-BOSE-AA is Pb-Free and RoHS compliant, as documented in the ordering information section listing "Pb-Free" for all NPA variants including 2SC536NF-NPA-AT and 2SC536NG-NPA-AT. ON Semiconductor's standard packaging for this family meets JEDEC J-STD-609 Category 1 requirements.

Can the 2SC536KE-BOSE-AA replace the 2SC536NG-NPA-AT in a design?

Yes, the 2SC536KE-BOSE-AA can replace the 2SC536NG-NPA-AT in most applications because both share identical absolute maximum ratings, electrical characteristics, package, and pinout. The "KE" suffix denotes a specific internal lot or test configuration within the same NPA-WA family, and no performance deviation is documented versus the NG variant.
