Product details
Overview
KSC2330ASHBU from Fairchild Semiconductor is an NPN epitaxial silicon transistor designed for high-voltage chroma output stages in color TV systems, featuring VCBO = 400 V, VCEO = 400 V, IC = 100 mA, PC = 1 W, and fT = 50 MHz (typ.).
For engineers reviewing the KSC2330ASHBU datasheet, pinout, applications, or equivalent options, key selection criteria include high-voltage breakdown capability, DC current gain classification (R/O), saturation voltage at defined drive conditions, and TO-92L package thermal derating behavior.
Technical Context
This device operates as a medium-power, high-voltage NPN switching transistor with specified breakdown voltages enabling use in horizontal deflection and chroma driver circuits. Its hFE classification (R: 40–65; O: 55–80) supports consistent gain binning for production line matching.
The 50 MHz fT and low Cob = 4 pF (at VCB = 10 V) support stable high-frequency amplification up to UHF chroma band, while VCE(sat) = 0.5 V at IC = 10 mA / IB = 1 mA ensures efficient on-state conduction with minimal power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | 400 V - Withstands 400 V reverse bias between collector and base, suitable for flyback pulse handling in TV horizontal output stages. |
| VCEO | 400 V - Sustains 400 V collector-emitter voltage under open-base condition, critical for chroma amplifier swing headroom. |
| hFE (R class) | 40–65 - Guaranteed DC current gain range for R-binned units, enabling predictable biasing in linear chroma driver designs. |
| VCE(sat) | 0.5 V max at IC = 10 mA / IB = 1 mA - Low saturation voltage minimizes conduction loss and self-heating during switching operation. |
| fT | 50 MHz typ. at VCE = 30 V / IC = 10 mA - Supports stable small-signal amplification across NTSC/PAL chroma subcarrier frequencies (3.58/4.43 MHz). |
| Cob | 4 pF at VCB = 10 V / f = 1 MHz - Low output capacitance reduces high-frequency loading and improves bandwidth in tuned RF stages. |
Pinout & Package
Package: TO-92L - Molded plastic case with 13.50 mm overall length, 3.90 mm body width, and 1.45 mm lead pitch; optimized for through-hole mounting and thermal dissipation in compact TV chassis layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; polarity defines NPN conduction direction and bias network reference. |
| 2 (Collector) | High-voltage output node | Handles up to 400 V swing; requires proper trace clearance and heatsinking in chroma output transformer coupling. |
| 3 (Base) | Control input | Drives transistor into saturation or cutoff; requires current-limited bias per hFE classification to ensure stable operating point. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage breakdown rating | VCBO/VCEO = 400 V enables direct replacement of legacy TV output transistors without circuit redesign. |
| Gain-binned hFE groups | R (40–65) and O (55–80) classifications allow selective assembly for consistent chroma signal amplitude across production batches. |
| Low saturation voltage | VCE(sat) ≤ 0.5 V at rated drive ensures <50 mW conduction loss, reducing thermal stress in sealed TV enclosures. |
| TO-92L mechanical standardization | Compatible with existing automated insertion equipment and wave solder profiles used in CRT TV manufacturing lines. |
Applications
| Color TV Chroma Output Stage | Video Signal Amplifier |
|---|---|
Use Scenario: Amplifying and buffering the 3.58 MHz (NTSC) or 4.43 MHz (PAL) chrominance subcarrier signal prior to matrix mixing and CRT drive. IC Role / Device Role / Timing Role: Linear NPN amplifier operating in Class-A or AB mode with fixed emitter degeneration for gain stability. Use Value: 400 V breakdown margin accommodates transient spikes from CRT yoke flyback coupling, preventing catastrophic failure during field service. | Use Scenario: Driving composite video output loads (75 Ω) in analog broadcast equipment requiring wideband fidelity up to 5 MHz. IC Role / Device Role / Timing Role: Medium-speed voltage follower with emitter-follower configuration to isolate source impedance from load. Use Value: 50 MHz fT and 4 pF Cob ensure flat group delay and minimal phase distortion across the entire video baseband. |
| Horizontal Deflection Driver | Legacy Monitor Video Output |
Use Scenario: Switching stage in simplified horizontal deflection auxiliary circuits where full H-output transistor is oversized. IC Role / Device Role / Timing Role: High-voltage switch controlling current flow through deflection yoke auxiliary windings or damper diode paths. Use Value: 100 mA IC rating and 1 W PC support intermittent duty-cycle operation with adequate thermal margin under 40°C ambient. | Use Scenario: RGB video buffer in early-generation VGA monitors and arcade video boards requiring discrete component reliability. IC Role / Device Role / Timing Role: DC-coupled emitter follower providing low-impedance drive to long coaxial cables feeding CRT grid inputs. Use Value: Tight hFE binning (R/O) ensures matched gain across red/green/blue channels, minimizing color registration drift over time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-voltage transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KSC2330YTA | Same die, TO-92 (not TO-92L); slightly longer leads and different lead pitch (2.54 mm vs. 1.27 mm). | Requires PCB footprint adjustment; not drop-in compatible due to mechanical mismatch. | Select only if legacy board design uses standard TO-92 and thermal derating allows same power dissipation. |
| 2SC3838 | Higher fT (120 MHz), lower VCEO (200 V), same hFE range; different gain binning structure. | Not suitable for 400 V chroma output; limited to low-voltage video preamp roles. | Choose only when system voltage rails are ≤150 V and bandwidth >80 MHz is required. |
Compared with KSC2330YTA and 2SC3838, the KSC2330ASHBU uniquely balances 400 V breakdown, TO-92L form factor, and chroma-optimized gain-bandwidth trade-off-making it irreplaceable in original CRT TV service and repair contexts where mechanical and electrical compatibility are jointly constrained.

FAQ
What is the maximum collector-emitter voltage rating for KSC2330ASHBU?
The KSC2330ASHBU has a guaranteed VCEO rating of 400 V at Ta = 25°C with IB = 0. This specification is validated per Fairchild's Rev. A2 datasheet and defines the absolute maximum voltage the device can withstand between collector and emitter before breakdown occurs. Exceeding this voltage risks permanent junction damage. The KSC2330ASHBU must be operated within this limit in all chroma output and deflection driver applications.
Does KSC2330ASHBU have a specified hFE range, and how is it binned?
Yes, the KSC2330ASHBU is binned into two hFE classifications: R (40–65) and O (55–80), measured at VCE = 10 V and IC = 20 mA. These bins appear as suffixes on packaging labels and enable consistent gain matching in multi-channel video circuits. The KSC2330ASHBU shipped by Aetrix Electronics carries documented hFE binning per lot traceability records.
What package type does KSC2330ASHBU use, and what are its key mechanical dimensions?
The KSC2330ASHBU uses the TO-92L package, a leaded through-hole variant with 13.50 mm overall length, 3.90 mm body width, and 1.27 mm lead pitch. Its pinout is Emitter (1), Collector (2), Base (3). The KSC2330ASHBU's TO-92L footprint differs from standard TO-92, requiring dedicated PCB layout and insertion tooling.
Can KSC2330ASHBU replace KSC2330YTA directly on a PCB?
No, the KSC2330ASHBU cannot directly replace KSC2330YTA without PCB modification. Although both share the same die, the KSC2330ASHBU uses TO-92L (1.27 mm lead pitch), whereas KSC2330YTA uses standard TO-92 (2.54 mm lead pitch). Attempting a direct swap would cause misalignment and solder joint failure. The KSC2330ASHBU requires its designated footprint.
What is the typical current gain bandwidth product (fT) of KSC2330ASHBU, and under what conditions is it measured?
The KSC2330ASHBU has a typical fT of 50 MHz, measured at VCE = 30 V, IC = 10 mA, and f = 1 MHz. This value reflects the frequency at which short-circuit current gain drops to unity and confirms suitability for NTSC/PAL chroma subcarrier amplification. The KSC2330ASHBU maintains usable gain well above 3.58/4.43 MHz, supporting clean harmonic response in analog video paths.
