Product details

Overview

2SC2690A-S1-AZ from Renesas Electronics is an NPN silicon epitaxial transistor designed for low- and high-frequency power amplification, with V_CEO = 160 V, f_T = 175 MHz (V_CE = 5.0 V, I_C = 0.2 A), h_FE2 = 60–320 at I_C = 0.3 A, and TO-126 (MP-5) package. It serves in TV vertical deflection output stages and audio amplifier driver stages up to 100 W.

For engineers reviewing the 2SC2690A-S1-AZ datasheet, 2SC2690A-S1-AZ pinout, 2SC2690A-S1-AZ application, or 2SC2690A-S1-AZ equivalent, key selection criteria include breakdown voltage margin, f_T-driven bandwidth capability, DC current gain consistency across operating current, thermal dissipation limits at T_C = 25°C, and complementary pairing with 2SA1220A PNP transistors.

Technical Context

This device operates as a linear NPN power transistor optimized for Class AB or Class B amplifier stages where high-voltage swing and moderate RF response are required. Its f_T of 175 MHz supports stable operation into VHF bands, while its 160 V V_CEO rating enables use in flyback and deflection circuits with significant inductive kickback.

The TO-126 package provides direct heatsink mounting via the collector tab, supporting 20 W total power dissipation at case temperature (T_C = 25°C), while maintaining safe junction temperature up to 150°C. h_FE is specified across two bias points-5 mA and 0.3 A-ensuring predictable gain behavior from small-signal drive to near-saturation conduction.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	160 V - Enables safe operation in TV vertical deflection circuits with high inductive energy recovery.
f_T	175 MHz - Supports stable amplification up to ~30 MHz fundamental with adequate gain margin for harmonic suppression.
h_FE2	60–320 at I_C = 0.3 A - Ensures reliable base drive design for 1 A collector current without excessive overdrive.
P_T (T_C = 25°C)	20 W - Allows direct heatsink mounting for continuous 1 A operation with ≤10°C/W thermal resistance.
V_CE(sat)	0.4–0.7 V at I_C = 1.0 A, I_B = 0.2 A - Limits conduction loss to <0.7 W in saturated switching applications.
C_ob	26 pF at V_CB = 10 V - Minimizes Miller effect distortion in tuned RF amplifier configurations.

Pinout & Package

2SC2690A-S1-AZ uses the TO-126 (MP-5) plastic package with collector-connected metal tab for thermal and electrical grounding. Pin 1 is Emitter, Pin 2 is Collector (tab), Pin 3 is Base - verified per Renesas D17501EJ2V0DS00 package drawing.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-impedance return path; requires low-inductance layout for stability at high f_T.
2 (Collector)	High-voltage output node	Electrically and thermally tied to metal tab; must be mounted to heatsink with insulated washer if chassis-ground referenced.
3 (Base)	Control input	Receives current-driven signal; requires series resistor to limit I_B ≤ 0.3 A DC and prevent thermal runaway.

Key Features

Feature	Design Value
High V_CEO rating	160 V enables use in TV vertical deflection output stages without external snubbing under nominal line conditions.
175 MHz f_T	Provides sufficient gain-bandwidth for broadband audio drivers and VHF RF amplifiers up to 30 MHz.
Complementary pairing	Designed as NPN counterpart to 2SA1220A, enabling matched push-pull amplifier designs with consistent thermal tracking.
TO-126 thermal performance	20 W P_T at T_C = 25°C allows compact heatsinking in space-constrained consumer electronics enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC2690A	No suffix - same electrical specs, Pb-free plating not guaranteed; S1-AZ denotes Pb-free electrode finish per JIS-C-0011.	Same functional role; S1-AZ ensures RoHS compliance for new production builds.	Select 2SC2690A-S1-AZ when lead-free assembly or export to EU markets is required.
MJE13005	Lower V_CEO (400 V), higher I_C(DC) (4 A), lower f_T (4 MHz); TO-220 package with isolated tab.	Better for high-voltage/low-frequency SMPS switching; unsuitable for >10 MHz RF due to limited f_T.	Choose MJE13005 only for high-current, low-frequency switching where bandwidth is not critical.

Compared with 2SC2690A and MJE13005, the 2SC2690A-S1-AZ uniquely balances 160 V breakdown, 175 MHz f_T, and TO-126 thermal efficiency - making it optimal for medium-power RF/audio amplification where both voltage headroom and frequency response matter.

FAQ

What is the maximum continuous collector current for 2SC2690A-S1-AZ?

The 2SC2690A-S1-AZ has a DC collector current rating of 1.2 A at T_A = 25°C. For sustained operation, thermal design must ensure junction temperature remains ≤150°C - typically achieved by mounting the TO-126 collector tab to a heatsink capable of dissipating ≥20 W at T_C = 25°C. Pulse current up to 2.5 A is allowed with PW ≤ 10 ms and duty cycle ≤ 50%.

Is 2SC2690A-S1-AZ pin-compatible with 2SC2690A?

Yes, 2SC2690A-S1-AZ is mechanically and electrically identical to 2SC2690A in pinout, package outline, and all electrical specifications. The "-S1-AZ" suffix indicates Pb-free external electrodes per JIS-C-0011, with no change to pin assignment (Emitter-Pin1, Collector-Pin2/tab, Base-Pin3) or internal die characteristics.

What is the typical h_FE range for 2SC2690A-S1-AZ at 0.3 A collector current?

The 2SC2690A-S1-AZ exhibits h_FE2 = 60–320 when measured at V_CE = 5.0 V and I_C = 0.3 A, per Renesas D17501EJ2V0DS00. This wide spread reflects standard binning (R/Q/P marking), and designers should verify gain in-circuit or select units with tighter h_FE tolerance if needed for matched pair applications.

Can 2SC2690A-S1-AZ replace 2SC2690 in existing designs?

Yes, 2SC2690A-S1-AZ can directly replace 2SC2690 in most cases: it shares the same TO-126 package, pinout, and exceeds 2SC2690's V_CEO (160 V vs. 120 V) and V_CBO ratings. However, confirm layout clearance for higher voltage margins and verify that the increased breakdown does not affect snubber or protection circuit timing in sensitive deflection applications.

What is the recommended heatsink interface for 2SC2690A-S1-AZ?

For optimal thermal performance, mount the 2SC2690A-S1-AZ collector tab (Pin 2) to an aluminum heatsink using thermal grease and an insulated shoulder washer (e.g., mica or silicone pad) to maintain electrical isolation. With a 10°C/W heatsink and ambient ≤40°C, the device sustains 1.2 A DC current while holding T_j ≤150°C - validated per the 20 W P_T rating at T_C = 25°C.
