Product details

Overview

2SC2690-AZ from Renesas Electronics is an NPN silicon epitaxial transistor designed for low- and high-frequency power amplification, with V_CEO = 120 V, f_T = 175 MHz (V_CE = 5.0 V, I_C = 0.2 A), h_FE2 = 60–140 at I_C = 0.3 A, and TO-126 (MP-5) package. It serves in audio amplifier driver stages (50–100 W) and TV vertical deflection output circuits.

For engineers reviewing the 2SC2690-AZ datasheet, 2SC2690-AZ pinout, 2SC2690-AZ application, or 2SC2690-AZ equivalent, key selection criteria include its 120 V V_CEO, 1.2 W ambient-rated power dissipation, complementary pairing with 2SA1220/2SA1220A, and Pb-free TO-126 construction verified per Renesas Document No. D17501EJ2V0DS00.

Technical Context

This discrete NPN bipolar junction transistor operates in linear amplification mode with DC current gain specified across two bias points: h_FE1 = 35–150 at I_C = 5 mA and h_FE2 = 60–140 at I_C = 0.3 A. Its 175 MHz f_T supports RF and audio frequency signal amplification up to VHF band edges.

The device features low saturation voltages-V_CE(sat) ≤ 0.7 V at I_C = 1.0 A / I_B = 0.2 A and V_BE(sat) ≤ 1.3 V-enabling efficient switching and Class AB amplifier operation. Cob = 26 pF at V_CB = 10 V ensures stable high-frequency impedance matching in tuned circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	120 V - maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating area in amplifier output stage design
f_T	175 MHz - unity-gain frequency at V_CE = 5 V, I_C = 0.2 A; enables use in VHF amplifiers and TV deflection circuits
h_FE2	60–140 - DC current gain at I_C = 0.3 A, V_CE = 5 V; determines base drive requirements for linear power amplification
P_T (T_A)	1.2 W - maximum ambient-rated power dissipation; requires heatsinking above ~0.5 W continuous operation
C_ob	26 pF - output capacitance at V_CB = 10 V, f = 1 MHz; impacts high-frequency stability and matching network design
V_CE(sat)	≤ 0.7 V - collector-emitter saturation voltage at I_C = 1.0 A, I_B = 0.2 A; minimizes conduction loss in switching or saturated-mode applications

Pinout & Package

2SC2690-AZ is housed in a TO-126 (MP-5) plastic package with 3 leads, rated for T_j = 150°C and T_stg = −55 to +150°C. The package features a metal tab for thermal mounting and standardized lead pitch compatible with industry-standard PCB footprints.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink terminal; connected to ground or low-impedance return path in common-emitter amplifier configuration
2	Collector	High-current output terminal; attached to heatsink via metal tab; carries full load current in power stage
3	Base	Control input terminal; requires current-limited drive (I_B(DC) ≤ 0.3 A) to avoid thermal runaway

Key Features

Feature	Design Value
High-voltage capability	V_CEO = 120 V supports operation in TV vertical deflection and mid-power audio output stages without cascading
High-frequency performance	f_T = 175 MHz enables stable amplification up to 50 MHz with adequate gain margin in broadband designs
Complementary PNP pairing	Designed as direct complement to 2SA1220/2SA1220A, enabling push-pull and quasi-complementary amplifier topologies
Pb-free construction	RoHS-compliant external electrodes meet EU Directive 2011/65/EU without requiring process requalification

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC2690	Same die, identical electrical specs, non-Pb-free plating; RoHS non-compliant external electrodes	No functional difference; unsuitable for new designs targeting EU markets post-RoHS compliance deadlines	Select 2SC2690-AZ for all new production where Pb-free compliance is required; legacy 2SC2690 may be used only in repair or non-regulated regions
2SC3854	V_CEO = 160 V, f_T = 120 MHz, h_FE2 = 70–240; higher voltage rating but lower f_T and wider h_FE spread	Better suited for higher-voltage deflection or SMPS applications; less optimal for VHF amplification due to reduced bandwidth	Choose 2SC3854 when V_CEO > 120 V is mandatory; retain 2SC2690-AZ where 175 MHz f_T and tight h_FE control are critical

Compared with 2SC2690 and 2SC3854, the 2SC2690-AZ delivers the optimal balance of high f_T, controlled h_FE spread, and RoHS compliance in a proven TO-126 platform-making it preferred for audio driver and VHF amplifier designs where both performance and regulatory alignment matter.

FAQ

What is the maximum collector-emitter voltage rating for the 2SC2690-AZ?

The 2SC2690-AZ has a maximum collector-emitter voltage (V_CEO) rating of 120 V at T_A = 25°C, as confirmed in Renesas Document No. D17501EJ2V0DS00. This rating applies under open-base conditions and defines the upper limit of safe DC or peak AC voltage across the collector and emitter terminals in linear or switching operation. Exceeding this value risks avalanche breakdown and permanent device failure.

Is the 2SC2690-AZ RoHS compliant?

Yes, the 2SC2690-AZ is RoHS compliant. Per Renesas' ordering information, the "-AZ" suffix explicitly denotes Pb-free external electrodes, satisfying EU Directive 2011/65/EU. This applies to solderable terminations only; internal die and packaging materials comply with standard Renesas "Standard" grade environmental specifications, and no exemption codes are required for typical industrial or consumer applications.

What is the gain-bandwidth product (f_T) of the 2SC2690-AZ and under what conditions is it measured?

The 2SC2690-AZ has a gain-bandwidth product (f_T) of 175 MHz, measured at V_CE = 5.0 V and I_C = 0.2 A, as specified in the Electrical Characteristics table of Renesas' D17501EJ2V0DS00 datasheet. This parameter reflects the frequency at which the transistor's short-circuit current gain drops to unity and is critical for determining usable bandwidth in RF and high-speed amplifier designs.

How does the 2SC2690-AZ differ from the 2SC2690A variant?

The 2SC2690-AZ differs from the 2SC2690A primarily in voltage rating: 2SC2690-AZ has V_CEO = 120 V, while 2SC2690A has V_CEO = 160 V. Both share the same TO-126 package, Pb-free marking (-AZ), and f_T = 175 MHz. The 2SC2690A also exhibits higher V_CBO (160 V vs. 120 V), making it suitable for higher-voltage deflection or SMPS applications where the 2SC2690-AZ would require derating.

What complementary PNP transistor pairs with the 2SC2690-AZ in push-pull amplifier designs?

The 2SC2690-AZ is explicitly designed as complementary to the 2SA1220 and 2SA1220A PNP transistors, as stated in the Features section of Renesas' D17501EJ2V0DS00 datasheet. These pairings match closely in V_CEO, f_T, and h_FE ranges, enabling balanced push-pull or quasi-complementary output stages in audio and RF amplifiers without significant crossover distortion.
