Product details
Overview
KSC2330YTA from onsemi is an NPN epitaxial silicon transistor designed for chroma output stages in color TV systems, featuring 300 V collector-base and collector-emitter breakdown voltage, 100 mA continuous collector current, 1 W power dissipation, and 50 MHz current gain bandwidth product (fT).
For engineers reviewing the KSC2330YTA datasheet, pinout, applications, or equivalent options, this device serves as a high-voltage, medium-frequency switching transistor with verified hFE classification Y (120–240), TO-92L package compatibility, and low saturation voltage under defined drive conditions.
Technical Context
The KSC2330YTA operates as a discrete NPN bipolar junction transistor optimized for chroma signal amplification and switching in analog video circuits. Its 300 V VCBO/VC EO ratings enable safe operation in CRT-based deflection and chroma driver stages where transient voltage spikes occur.
With fT = 50 MHz (typ.), Cob = 4 pF at VCB = 10 V, and VCE(sat) = 0.5 V at IC = 10 mA / IB = 1 mA, the device supports stable small-signal gain and fast turn-on/turn-off behavior while maintaining low output capacitance for minimal signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO / VCEO | 300 V - Supports high-voltage chroma output stages without breakdown under transient stress in color TV deflection circuits. |
| IC (max) | 100 mA - Sufficient drive capability for chroma modulator and output buffer loads in legacy analog video systems. |
| fT | 50 MHz (typ.) - Enables faithful amplification of chroma subcarrier frequencies (3.58 MHz NTSC / 4.43 MHz PAL) with margin. |
| hFE (Y-class) | 120–240 - Tight DC current gain bin ensures predictable biasing and consistent stage gain across production units. |
| VCE(sat) | 0.5 V at IC = 10 mA, IB = 1 mA - Low saturation voltage reduces power loss and thermal rise in linear and switching modes. |
| Cob | 4 pF at VCB = 10 V, f = 1 MHz - Minimizes Miller effect and high-frequency loading in tuned chroma amplifier designs. |
Pinout & Package
Package: TO-92L (Case 135AM), lead-formed, 3-pin through-hole plastic package with standard E-C-B pin order (Emitter–Collector–Base).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; defines reference for base drive and collector current flow. |
| 2 (Collector) | High-voltage output node | Drives chroma load (e.g., IF transformer or modulator tank circuit); rated for 300 V reverse bias. |
| 3 (Base) | Control input | Accepts current-limited drive (e.g., via resistor from previous stage); controls collector current per hFE relationship. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage rating | 300 V VCBO and VCEO - Eliminates need for external snubbers in CRT chroma output stages exposed to flyback transients. |
| Y-class hFE binning | 120–240 gain range - Reduces unit-to-unit variation in bias point and AC gain, simplifying production calibration. |
| Low VCE(sat) | 0.5 V at 10 mA/1 mA - Limits conduction loss and self-heating during sustained chroma signal peaks. |
| Controlled Cob | 4 pF output capacitance - Preserves Q-factor in parallel-tuned chroma circuits and avoids unintended frequency pulling. |
Applications
| Color TV Chroma Output Stage | Video Signal Amplifier |
|---|---|
Use Scenario: Final amplification of 3.58 MHz (NTSC) or 4.43 MHz (PAL) chrominance signals before modulation onto RF carrier. IC Role / Device Role / Timing Role: Linear Class-A/B amplifier with emitter-follower or common-emitter configuration delivering low-distortion chroma drive. Use Value: 300 V rating withstands CRT horizontal retrace transients; 50 MHz fT ensures flat response across chroma band. |
Use Scenario: Boosting composite video or Y/C separated signals in analog video distribution equipment. IC Role / Device Role / Timing Role: Medium-speed voltage/current gain stage with stable DC operating point and minimal phase shift. Use Value: Tight hFE binning (Y) enables repeatable gain setting; low Cob prevents high-frequency roll-off in 5–10 MHz video paths. |
| Legacy CRT Monitor Driver | Analog Video Test Equipment |
Use Scenario: Driving chroma section of RGB or YUV decoding circuitry in professional CRT monitors. IC Role / Device Role / Timing Role: High-voltage switch/amplifier interfacing between decoder IC outputs and CRT gun driver transformers. Use Value: 1 W power dissipation accommodates intermittent peak loads; TO-92L form factor fits dense legacy PCB layouts. |
Use Scenario: Signal conditioning in benchtop video waveform generators or pattern analyzers requiring stable analog gain blocks. IC Role / Device Role / Timing Role: Precision gain element in calibrated test signal chains where repeatability and low noise are critical. Use Value: Verified 0.1 µA ICBO at 200 V ensures negligible leakage-induced offset drift over time and temperature. |
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 |
|---|---|---|---|
| KSC2330OTA | Same die, R-class hFE (40–80); lower gain consistency and higher VCE(sat) variability. | Suitable for non-critical switching where gain tolerance >100% is acceptable. | Select only when cost sensitivity outweighs gain stability requirements in chroma buffer roles. |
| MPSA42 | Higher VCBO (300 V) but lower fT (250 MHz min), larger Cob (12 pF), TO-92 package (not lead-formed). | Better for general-purpose HV switching; less optimal for chroma band fidelity due to higher capacitance. | Prefer KSC2330YTA where chroma subcarrier integrity and low-output-capacitance are design priorities. |
Compared with KSC2330OTA and MPSA42, the KSC2330YTA delivers superior chroma-band fidelity via tighter hFE control and lower Cob, making it the preferred choice for legacy color TV chroma output where signal purity and transient immunity are jointly required.

FAQ
What is the hFE classification of KSC2330YTA and how does it affect circuit design?
The KSC2330YTA is classified as "Y", indicating a DC current gain (hFE) range of 120–240 at VCE = 10 V and IC = 20 mA. This tight binning allows designers to set precise bias points without gain-dependent recalibration, improving consistency in chroma amplifier gain and linearity across production units of KSC2330YTA.
Can KSC2330YTA replace KSC2330OTA in existing designs?
KSC2330YTA can replace KSC2330OTA electrically and mechanically, but its higher and tighter hFE range (120–240 vs. 40–80) may require minor base resistor adjustment to maintain the same quiescent collector current. The KSC2330YTA offers improved gain stability and lower VCE(sat) variation, enhancing performance in chroma output stages where signal fidelity matters.
What is the maximum safe operating voltage for KSC2330YTA in chroma output applications?
The KSC2330YTA is rated for VCBO = 300 V and VCEO = 300 V at Ta = 25°C. In chroma output applications with CRT flyback transients, it safely handles repetitive 250 V peak collector swings with derated power dissipation above 25°C ambient, per the published power derating curve in the KSC2330YTA datasheet.
Does KSC2330YTA meet RoHS requirements?
Yes, KSC2330YTA is RoHS-compliant and lead-free per onsemi's product change notifications and material declarations. It conforms to Directive 2011/65/EU and subsequent amendments, with homogeneous material lead content below 1000 ppm, verified through onsemi's certified supply chain testing protocols for KSC2330YTA.
What is the thermal resistance junction-to-ambient (RθJA) for KSC2330YTA in TO-92L package?
The KSC2330YTA in TO-92L package has a typical RθJA of 200°C/W under standard JEDEC test conditions (single-layer PCB, 1-inch² copper pad). Actual thermal performance depends on PCB layout; adding thermal relief traces or local copper pour improves heat dissipation and extends safe operation near its 1 W PC limit.
