Product details

Overview

2SA608F-NP-AA from onsemi is a PNP 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 –100 mA/–10 mA drive, h_FE of 160–320 (Rank F), and f_T of 200 MHz - used in low-to-high-frequency amplifier and switching stages in consumer audio and signal routing circuits.

For engineers reviewing the 2SA608F-NP-AA datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE binning (Rank F), TO-92-compatible SC-43A package dimensions, and guaranteed f_T performance across –25°C to +75°C operating range.

Technical Context

This PNP transistor operates with emitter-grounded configuration and supports linear amplification up to 200 MHz due to its specified f_T. Its low saturation voltage enables efficient switching in low-power logic interface and relay driver circuits where base drive current is constrained.

The device uses silicon planar epitaxial construction with wide ASO (Area Safe Operating) margin, enabling robust handling of pulsed currents up to –400 mA (I_CP) without secondary breakdown - critical for transient load control in analog front-ends and power management blocks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–50 V - maximum allowable collector-emitter voltage under open-base condition; defines safe operating ceiling for biasing in negative-rail circuits
I_C	–150 mA - continuous DC collector current rating; sets upper limit for steady-state load switching or amplification
V_CE(sat)	–0.3 V @ –100 mA/–10 mA - ensures minimal conduction loss in saturated switch mode, reducing heat generation
h_FE	160–320 (Rank F) - guaranteed DC current gain range at –6 V V_CE, –1 mA I_C; enables predictable base resistor sizing
f_T	200 MHz - usable bandwidth for small-signal amplification; supports RF preamp and oscillator buffer roles up to VHF
P_C	500 mW - thermal dissipation limit at T_a = 25°C; requires heatsinking or derating above ambient 50°C
C_ob	3.0 pF @ –6 V V_CB - output capacitance affecting high-frequency gain roll-off and stability in tuned circuits

Pinout & Package

2SA608F-NP-AA is housed in SC-43A package (equivalent to TO-92, TO-226AA, SOT-54), with 3-terminal through-hole mounting, 0.19 g mass, and standardized lead spacing (2.54 mm pitch). Dimensions: 4.5 mm length × 3.7 mm width × 4.0 mm height (max).

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit terminal in PNP operation; connected to most positive rail in common-emitter switch configurations
2	Collector	Current entry terminal; tied to load or pull-down network; voltage swing referenced to emitter
3	Base	Control input; requires current-limited drive to achieve target I_C based on h_FE binning

Key Features

Feature	Design Value
Low V_CE(sat)	–0.3 V enables <100 mW conduction loss at 100 mA, improving efficiency in battery-powered switches
Wide ASO	Robust secondary breakdown immunity supports 400 mA pulsed loads without SOA violation
High f_T	200 MHz gain-bandwidth allows stable amplification up to 30 MHz with adequate phase margin
Rank-F h_FE	160–320 spread ensures consistent gain matching in matched-pair amplifier designs
Pb-Free packaging	Complies with RoHS Directive 2011/65/EU; suitable for lead-free reflow and wave soldering processes

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SA1015GR	V_CEO = –50 V, I_C = –150 mA, but h_FE = 200–400 (Rank GR); f_T not specified	Lacks guaranteed f_T spec; unsuitable for >10 MHz amplification	Select when only DC gain and switching are required; avoid in RF-coupled stages
BC557B	V_CEO = –45 V, I_C = –100 mA, h_FE = 200–450; same SC-43A package	Lower voltage and current ratings reduce margin in 12 V relay drivers	Acceptable for 5 V logic-level switching; verify V_CEO derating in 9 V+ systems

Compared with 2SA608F-NP-AA, 2SA1015GR offers higher h_FE but no f_T guarantee, while BC557B fits the same footprint but sacrifices 10% voltage headroom and 33% current capacity - making 2SA608F-NP-AA optimal for cost-sensitive, frequency-aware PNP switching where V_CEO ≥ –50 V and f_T ≥ 200 MHz are design requirements.

FAQ

What is the exact package type of 2SA608F-NP-AA?

The 2SA608F-NP-AA uses the SC-43A package, which is mechanically and dimensionally identical to TO-92, TO-226AA, and SOT-54 - confirmed by onsemi's ordering information and outline drawing No. 7542-001. Lead spacing is 2.54 mm, body height is 4.0 mm max, and it is Pb-Free compliant per J-STD-609.

Does 2SA608F-NP-AA have a guaranteed f_T specification?

Yes, the 2SA608F-NP-AA has a minimum f_T of 200 MHz at V_CE = –6 V and I_C = –10 mA, as specified in the Electrical Characteristics table of the official datasheet (No. 6324-2/6). This value is tested and binned - not typical - ensuring usable bandwidth in VHF amplifier designs.

What does the "F" in 2SA608F-NP-AA signify?

The "F" denotes the h_FE rank bin: 2SA608F-NP-AA is guaranteed to have DC current gain between 160 and 320 at V_CE = –6 V and I_C = –1 mA. This binning enables predictable base resistor calculation and matching in differential pair or current mirror circuits.

Can 2SA608F-NP-AA replace 2SA608N in existing designs?

Yes, 2SA608F-NP-AA is a direct replacement for 2SA608N - both share identical absolute maximum ratings, electrical characteristics, SC-43A package, and pinout (Emitter=1, Collector=2, Base=3). The "F" suffix confirms Rank F h_FE binning, whereas 2SA608N is the base part number without rank designation.

Is 2SA608F-NP-AA suitable for high-frequency oscillator applications?

The 2SA608F-NP-AA supports oscillator use up to ~30 MHz due to its 200 MHz f_T and low C_ob (3.0 pF), but it is not optimized for VCOs or crystal-controlled oscillators requiring ultra-low phase noise. It is validated for Colpitts and Hartley topologies in low-cost RF transmitter stages where gain stability matters more than jitter.
