Product details
Overview
KSC2330OTA from onsemi is an NPN epitaxial silicon transistor designed for high-voltage chroma output stages in color TV systems, featuring VCBO and VCEO ratings of 300 V, IC = 100 mA, PC = 1 W, and fT = 50 MHz (typical) at VCE = 30 V and IC = 10 mA.
For engineers reviewing the KSC2330OTA datasheet, pinout, applications, or equivalent options, key selection criteria include high-voltage breakdown capability, DC current gain classification (R/O/Y), saturation voltage under defined drive conditions, and TO-92L package thermal and layout compatibility.
Technical Context
The KSC2330OTA operates as a general-purpose high-voltage NPN switching and amplification transistor with fully specified absolute maximum ratings and electrical characteristics at Ta = 25°C. Its hFE classification (R: 40–80, O: 70–140, Y: 120–240) enables gain-binned selection for consistent circuit performance.
It delivers low VCE(sat) = 0.5 V at IC = 10 mA and IB = 1 mA, supports high-frequency operation up to 50 MHz typical fT, and exhibits minimal Cob = 4 pF at VCB = 10 V - making it suitable for chroma signal amplification where bandwidth, linearity, and voltage headroom are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO / VCEO | 300 V - Enables safe operation in color TV chroma output circuits with high-swing video signals and flyback-related transients. |
| IC (max) | 100 mA - Supports moderate-current driver stage requirements without secondary amplification. |
| PC (max) | 1 W - Allows direct mounting on PCB without heatsink in low-duty-cycle chroma output applications. |
| fT (typ.) | 50 MHz - Ensures adequate bandwidth for chroma signal fidelity up to ~3–4 MHz baseband with margin. |
| VCE(sat) | 0.5 V @ IC = 10 mA, IB = 1 mA - Minimizes power loss and self-heating during saturated switching operation. |
| hFE range | 40–240 (Y-class: 120–240) - Provides design flexibility for bias stability and gain-critical amplifier configurations. |
| Cob | 4 pF @ VCB = 10 V - Limits Miller-effect capacitance to preserve high-frequency response in common-emitter stages. |
Pinout & Package
Package: TO-92L (Case 135AM), lead-formed, 3-pin through-hole package with standard JEDEC outline and thermal rating compatible with manual or wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; polarity defines NPN operation and bias direction. |
| 2 (Collector) | High-voltage output node | Handles up to 300 V swing; interfaces directly with chroma load (e.g., CRT grid or filter network). |
| 3 (Base) | Control input | Receives current-limited drive (e.g., from preceding transistor or IC); gain binning affects required IB for target IC. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage breakdown | 300 V VCBO/VCEO ensures robustness against CRT flyback-induced voltage spikes in legacy TV designs. |
| Gain-binned hFE | Three classifications (R/O/Y) allow precise DC bias setting without trimming resistors in production. |
| Low saturation voltage | VCE(sat) ≤ 0.5 V reduces conduction loss and improves efficiency in linear and switching chroma output stages. |
| Controlled output capacitance | Cob = 4 pF minimizes high-frequency roll-off and phase shift in wideband video amplifier topologies. |
| TO-92L mechanical form | Standardized footprint enables drop-in replacement and compatibility with legacy assembly tooling and test fixtures. |
Applications
| Color TV Chroma Output Stage | Video Signal Amplifier |
|---|---|
|
Use Scenario: Final-stage amplification of demodulated chrominance signal before CRT grid drive in analog color television receivers. IC Role / Device Role / Timing Role: NPN transistor operating in common-emitter configuration to provide voltage gain and current drive into capacitive CRT grid load. Use Value: 300 V breakdown withstands flyback overshoot; 50 MHz fT preserves chroma bandwidth; TO-92L simplifies service replacement. |
Use Scenario: Wideband amplification of composite or component video signals in broadcast monitoring equipment and legacy test gear. IC Role / Device Role / Timing Role: Linear amplifier biased in Class-A or AB mode to maintain low THD across 0.5–5 MHz frequency range. Use Value: Low VCE(sat) and controlled Cob ensure flat group delay and minimal amplitude distortion in video passband. |
| High-Voltage Switching Driver | Analog Signal Conditioning |
|
Use Scenario: Driving moderate-current loads (e.g., relay coils, small solenoids) in industrial control panels requiring >200 V standoff. IC Role / Device Role / Timing Role: Saturated switch with fixed base drive, leveraging high hFE to minimize driver-stage loading. Use Value: 100 mA IC rating and 1 W dissipation support intermittent duty cycles without thermal derating beyond 25°C ambient. |
Use Scenario: DC-coupled gain stage in precision analog instrumentation where offset stability and gain linearity matter. IC Role / Device Role / Timing Role: Discrete transistor in emitter-follower or common-collector buffer configuration for impedance transformation. Use Value: Tight hFE binning (Y-class) enables predictable bias current and stable quiescent point across temperature and unit variance. |
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, Y-class hFE (120–240) vs. KSC2330OTA's O-class (70–140); identical max ratings and package. | Preferred where higher and more consistent DC gain is needed for tighter bias control in amplifier stages. | Select KSC2330YTA when circuit requires guaranteed minimum hFE ≥ 120 at IC = 20 mA and VCE = 10 V. |
| MPSA43 | Lower VCBO/VCEO = 200 V; fT = 50 MHz same; hFE = 40–250 (unbinned); TO-92 package (not lead-formed). | Suitable for lower-voltage video or general-purpose switching where 300 V margin is not required. | Choose MPSA43 only if system-level transient analysis confirms <200 V peak collector stress and board layout accommodates non-lead-formed TO-92. |
Compared with KSC2330OTA, KSC2330YTA offers higher guaranteed hFE for improved bias stability, while MPSA43 trades 100 V breakdown margin for broader hFE distribution and non-lead-formed packaging - neither is pin-compatible without layout verification.

FAQ
What is the maximum collector-emitter voltage rating for the KSC2330OTA?
The KSC2330OTA has a maximum collector-emitter voltage (VCEO) rating of 300 V at Ta = 25°C. This specification is validated under test condition IC = 5 mA and IB = 0. Exceeding this voltage risks avalanche breakdown and permanent device failure. Designers must account for transient overvoltage in applications like CRT flyback circuits when using the KSC2330OTA.
Does the KSC2330OTA have a specified hFE classification, and what does "OTA" signify?
Yes, the KSC2330OTA is O-class hFE binned (70–140) at VCE = 10 V and IC = 20 mA. The "OTA" suffix denotes the O-class gain bin and TO-92L package variant per onsemi's standardized nomenclature. This binning allows predictable biasing without post-manufacture sorting, and is confirmed in the official KSC2330 datasheet Rev. 2 (October 2018).
Can the KSC2330OTA be used as a direct replacement for the KSC2330YTA?
No - the KSC2330OTA and KSC2330YTA share identical package, pinout, and absolute maximum ratings, but differ in hFE classification: OTA is O-class (70–140), while YTA is Y-class (120–240). Substituting KSC2330OTA for KSC2330YTA may cause insufficient gain or bias drift in circuits relying on minimum hFE ≥ 120. Always verify DC operating point when interchanging these variants.
What is the typical current gain bandwidth product (fT) of the KSC2330OTA, and under what conditions is it measured?
The typical current gain bandwidth product (fT) of the KSC2330OTA is 50 MHz, measured at VCE = 30 V, IC = 10 mA, and f = 1 MHz. This value reflects small-signal high-frequency performance and is not guaranteed minimum - actual fT varies with operating point and temperature. For chroma amplifier designs, this fT provides usable bandwidth up to ~3–4 MHz with margin.
Is the KSC2330OTA RoHS compliant and halogen-free?
Yes, the KSC2330OTA is RoHS compliant and halogen-free per onsemi's material declarations and product change notifications. It meets EU Directive 2011/65/EU and IEC 61249-2-21:2013 requirements. Full compliance documentation, including substance thresholds and test reports, is available via onsemi's Quality & Reliability portal using the KSC2330OTA part number.
