Product details
Overview
KSC2316OTA from ON Semiconductor is an NPN epitaxial silicon transistor in TO-92L package, rated for 120 V CBO/CEO, 800 mA collector current, 900 mW power dissipation, and 120 MHz fT, designed for audio power amplifier and driver-stage applications.
For engineers reviewing the KSC2316OTA datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal derating data, hFE classification bands, saturation voltage at 500 mA, and complementary pairing with KSA916 - all confirmed from Fairchild/ON Semiconductor official documentation.
Technical Context
This device operates as a general-purpose medium-power NPN bipolar junction transistor with fixed-emitter configuration and non-hermetic plastic TO-92L packaging. Its 120 V breakdown ratings support high-voltage audio output stages, while its 120 MHz fT enables stable gain up to mid-audio frequencies.
The KSC2316OTA exhibits two hFE classifications (O: 80–160; Y: 120–240) at IC = 100 mA, VCE = 5 V, and maintains VCE(sat) ≤ 1.0 V at IC = 500 mA / IB = 50 mA - confirming suitability for linear amplification and switching in low-to-medium speed analog circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO / VCEO | 120 V - supports operation in audio output stages with rail voltages up to ±60 V DC without breakdown. |
| IC(max) | 800 mA - enables drive capability for small loudspeakers or pre-driver loads in Class-A/B amplifiers. |
| PD @ 25°C | 900 mW - defines maximum continuous dissipation at ambient; derates 7.2 mW/°C above 25°C. |
| fT | 120 MHz - ensures usable small-signal gain up to ~100 kHz with margin for stability in feedback designs. |
| VCE(sat) | ≤1.0 V @ IC = 500 mA, IB = 50 mA - confirms low conduction loss in saturated-switching roles like relay drivers. |
| Cob | 30 pF @ VCB = 10 V - limits Miller effect in high-gain amplifier stages; manageable with standard compensation. |
Pinout & Package
Package: TO-92L (3-lead, non-JEDEC 8 mm tall body, lead form TA type), with standardized pinout when viewed from flat side, leads down: Emitter (1), Collector (2), Base (3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current exit path, common reference node | Connected to ground or negative rail in common-emitter configurations; sets bias point stability. |
| 2 (Collector) | Current input path, output terminal | Drives load (e.g., speaker transformer or next-stage base); handles full collector current and voltage swing. |
| 3 (Base) | Control input, current-controlled gate | Receives drive current (e.g., from previous stage or microcontroller); requires series resistor to limit IB per hFE requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary pair to KSA916 | Enables balanced push-pull output stages in discrete audio amplifiers without topology redesign. |
| hFE classification bands (O/Y) | Allows binning for consistent gain matching in production amplifier modules or matched-dual designs. |
| Low VCE(sat) at high IC | Reduces power loss and heat generation in driver applications operating near 500 mA load current. |
| 130 °C/W RθJA | Defines thermal interface requirement: needs ≥1 cm² copper pour on PCB for sustained 500 mA operation at 50°C ambient. |
Applications
| Audio Power Amplifier | Driver Stage Amplifier |
|---|---|
Use Scenario: Final output stage in portable mono audio amplifiers delivering 0.5–1 W into 8 Ω speakers. IC Role / Device Role / Timing Role: NPN output transistor in Class-A/B common-emitter configuration, biased by resistive divider and emitter degeneration. Use Value: 120 V rating accommodates ±45 V rails; 800 mA IC and 900 mW PD support peak power delivery without thermal runaway. | Use Scenario: Voltage/current gain stage driving the base of a higher-power output transistor (e.g., TIP31C) in multi-stage amplifiers. IC Role / Device Role / Timing Role: Medium-gain, medium-speed active element providing isolation and current multiplication between preamp and power stage. Use Value: 120 MHz fT ensures bandwidth beyond audio range; low Cob minimizes phase shift in feedback loops. |
| Discrete Push-Pull Output | Relay / Solenoid Driver |
Use Scenario: Complementary NPN/PNP pair (KSC2316OTA + KSA916) forming Class-B output stage in low-cost discrete op-amp or headphone amp designs. IC Role / Device Role / Timing Role: NPN half of symmetrical output stage, sourcing current to load during positive half-cycle. Use Value: Matched hFE bands (Y-class) enable balanced crossover behavior and reduced even-order distortion. | Use Scenario: Direct-drive interface between microcontroller GPIO and 12 V/500 mA electromagnetic relay coil. IC Role / Device Role / Timing Role: Saturated switch controlling coil current; base driven via current-limiting resistor from logic-level signal. Use Value: VCE(sat) ≤ 1.0 V at 500 mA ensures < 0.5 W dissipation; TO-92L package fits compact control boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA42 | Higher VCBO (300 V), lower IC (500 mA), same TO-92 package | Better suited for high-voltage low-current applications (e.g., CRT deflection, HV bias supplies); not recommended for >500 mA loads | Select MPSA42 only when voltage >160 V is required and current remains ≤500 mA. |
| BC547C | Lower VCBO (50 V), lower IC (100 mA), same pinout but smaller PD (500 mW) | Restricted to low-voltage signal amplification (e.g., preamp, sensor interface); unsuitable for power output or driver roles | Choose BC547C only for sub-100 mA, <30 V signal-chain use - not a functional replacement for KSC2316OTA. |
Compared with MPSA42 and BC547C, the KSC2316OTA uniquely balances 120 V breakdown, 800 mA current, and 900 mW dissipation in TO-92L - making it a targeted solution for medium-power audio and driver applications where both voltage headroom and current delivery matter.

FAQ
What is the pin configuration of the KSC2316OTA?
The KSC2316OTA uses a TO-92L package with leads down and flat side facing viewer: Pin 1 is Emitter, Pin 2 is Collector, Pin 3 is Base. This configuration is documented in Figure 6 of the official KSC2316 Rev. 1.4 datasheet and matches JEDEC-standard orientation for lead-form TA devices. The KSC2316OTA must be mounted with correct pin alignment to avoid circuit malfunction.
Does the KSC2316OTA have a specified hFE range at high current?
Yes - the KSC2316OTA specifies hFE2 (DC current gain) at VCE = 5 V, IC = 100 mA: minimum 80, maximum 240, with two classification bands (O: 80–160; Y: 120–240). This high-current hFE band is critical for predicting gain in driver-stage operation and is explicitly defined in the Electrical Characteristics table of the KSC2316OTA datasheet.
Can the KSC2316OTA replace the KSC2316YTA?
Yes - KSC2316OTA and KSC2316YTA are identical in electrical specifications, package (TO-92L), and marking (C2316). The "OTA" suffix reflects ON Semiconductor's post-Fairchild nomenclature update replacing underscore with dash; no functional or parametric change occurred. The KSC2316OTA is the current orderable part number for the same device formerly labeled KSC2316_YTA.
What is the maximum safe operating temperature for the KSC2316OTA?
The KSC2316OTA has a maximum junction temperature (TJ) of 150°C and storage temperature range of –55°C to +150°C. To maintain reliability, junction temperature must stay below 150°C under operating conditions - requiring thermal design that accounts for PD derating (7.2 mW/°C above 25°C) and PCB copper area. The KSC2316OTA's RθJA of 130°C/W defines the worst-case thermal path from junction to ambient.
Is the KSC2316OTA suitable for switching applications?
Yes - the KSC2316OTA supports switching use with VCE(sat) ≤ 1.0 V at IC = 500 mA / IB = 50 mA, and Cob = 30 pF limiting switching speed. It is appropriate for low-frequency (<100 kHz) switching tasks such as relay control or LED array drivers. For high-speed switching, consider devices with lower Cob and faster recovery; the KSC2316OTA remains optimal where simultaneous voltage headroom, current capacity, and cost efficiency are prioritized.
