Product details
Overview
KSC2316YTA from ON Semiconductor is an NPN epitaxial silicon transistor in TO-92L package, rated for 120 V VCEO, 800 mA IC, and 900 mW PD, with hFE of 120–240 at 100 mA, used in audio power amplifier driver stages and complementary to KSA916.
For engineers reviewing the KSC2316YTA datasheet, pinout, applications, or equivalent options, this discrete NPN transistor supports mid-power linear amplification, offers 120 MHz fT, low VCE(sat) (1 V @ 500 mA), and operates up to 150 °C junction temperature in through-hole audio and industrial control circuits.
Technical Context
The KSC2316YTA is a general-purpose NPN bipolar junction transistor optimized for linear amplification and switching in driver-stage applications. Its epitaxial base structure enables high current gain bandwidth product (120 MHz) and stable hFE across collector currents from 10 mA to 100 mA.
It features symmetrical breakdown ratings (VCBO = VCEO = 120 V), low leakage (ICBO ≤ 0.1 μA), and thermal performance validated on FR-4 PCB (RθJA = 130 °C/W). The device is not intended for RF power amplification or switching above 100 kHz without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 120 V - Supports operation in 100 V rail audio amplifiers without breakdown risk |
| IC | 800 mA - Sufficient for driver-stage load currents in Class AB output stages |
| PD | 900 mW - Enables continuous operation at ~700 mW on standard FR-4 board at 25 °C ambient |
| hFE | 120–240 @ IC = 100 mA - Ensures predictable bias stability in emitter-follower and common-emitter configurations |
| fT | 120 MHz - Allows use in wideband audio pre-driver and broadband signal conditioning up to ~10 MHz |
| VCE(sat) | 1 V @ IC = 500 mA, IB = 50 mA - Minimizes conduction loss and self-heating in saturated switching applications |
| Cob | 30 pF @ VCB = 10 V - Limits Miller effect in high-gain amplifier stages operating below 10 MHz |
Pinout & Package
Package: TO-92L (3-lead, non-JEDEC, 8 mm tall body, lead form TA type).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; polarity defines NPN operation |
| 2 (Collector) | Current source terminal | Drives load toward positive supply; handles full IC and VCEO stress |
| 3 (Base) | Control input terminal | Receives forward-biased drive current (typically 5–50 mA) to saturate or linearly bias the transistor |
Key Features
| Feature | Design Value |
|---|---|
| Complementary pairing | Explicitly designed as NPN complement to KSA916 PNP, enabling matched push-pull stage design |
| High fT | 120 MHz gain-bandwidth supports wideband audio driver and broadband signal buffering |
| Low saturation voltage | VCE(sat) = 1 V at 500 mA enables efficient switching in relay drivers and LED current sources |
| Stable hFE classification | Y-grade hFE2 = 120–240 ensures consistent DC bias point across production lots in linear amplifiers |
Applications
| Audio Power Amplifier Driver | Relay/LED Driver Stage |
|---|---|
Use Scenario: Driving the base of output transistors in Class AB audio amplifiers with ±40 V rails. IC Role / Device Role / Timing Role: NPN driver transistor providing current gain and voltage swing to reduce loading on preceding voltage amplifier stage. Use Value: Delivers stable hFE and low VCE(sat) to minimize crossover distortion and thermal drift in quasi-complementary output stages. | Use Scenario: Switching 12 V/500 mA relays or high-brightness LEDs in industrial control panels. IC Role / Device Role / Timing Role: General-purpose NPN switch controlled by microcontroller GPIO or logic-level signal. Use Value: Withstood 120 V VCEO and 800 mA IC, it safely absorbs inductive kickback and sustains repetitive switching without snubber networks. |
| Complementary Push-Pull Pair | DC Motor Speed Control |
Use Scenario: Paired with KSA916 in symmetrical emitter-follower output buffers for op-amp-based instrumentation. IC Role / Device Role / Timing Role: NPN half of complementary pair delivering bidirectional current sourcing/sinking capability. Use Value: Matched VCEO, hFE range, and thermal characteristics with KSA916 enable balanced linearity and reduced even-order harmonic distortion. | Use Scenario: Controlling direction and speed of small brushed DC motors (≤24 V, ≤600 mA) in robotics and automation. IC Role / Device Role / Timing Role: Low-side switch in H-bridge or single-direction PWM driver stage. Use Value: 900 mW PD and 130 °C/W RθJA allow continuous 500 mA PWM operation at 25 °C ambient without heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC548C | Lower VCEO (30 V), lower IC (100 mA), lower fT (300 MHz but limited by low voltage rating) | Suitable only for low-voltage signal amplification, not driver or power stages | Select BC548C only for sub-12 V, <100 mA small-signal applications where cost and footprint are prioritized over voltage headroom |
| MPSA18 | Higher VCEO (50 V), higher hFE (100–300), same TO-92 package but lower PD (625 mW) | Not rated for 120 V operation; unsuitable for high-rail audio or inductive load switching | Choose MPSA18 for high-gain, low-noise preamplifier stages where voltage stress is ≤50 V and power dissipation remains <600 mW |
Compared with BC548C and MPSA18, the KSC2316YTA uniquely combines 120 V breakdown, 800 mA current capability, and 900 mW power dissipation in TO-92L-making it suitable for mid-power driver roles where both voltage headroom and current delivery are required.

FAQ
What is the maximum collector-emitter voltage rating for KSC2316YTA?
The KSC2316YTA has a maximum collector-emitter voltage (VCEO) rating of 120 V at TA = 25 °C. This rating applies under specified test conditions (IC = 10 mA, IB = 0) and must be derated at elevated ambient temperatures per the device's thermal characteristics. Operation above this voltage risks irreversible breakdown.
Is KSC2316YTA pin-compatible with KSA916?
No, KSC2316YTA is not pin-compatible with KSA916. While they are complementary NPN/PNP devices intended for paired use, KSC2316YTA uses TO-92L pinout (Emitter–Collector–Base), whereas KSA916 follows the same mechanical package but requires verification of its specific pin assignment-Fairchild documentation confirms KSA916 uses E–C–B order, matching KSC2316YTA, but absolute compatibility depends on layout tolerances and thermal coupling in shared PCB footprints.
What is the hFE range for KSC2316YTA at 100 mA collector current?
The KSC2316YTA Y-grade variant has a guaranteed hFE range of 120 to 240 when measured at VCE = 5 V and IC = 100 mA. This classification is marked as "Y" on the top of the device (C2316) and is confirmed in the official datasheet Rev. 1.4. Designers should use the minimum value (120) for worst-case bias calculations.
Can KSC2316YTA be used in switching applications?
Yes, KSC2316YTA can be used in switching applications such as relay drivers and LED current control, provided operating conditions remain within its absolute maximum ratings: VCE ≤ 120 V, IC ≤ 800 mA, and PD ≤ 900 mW. Its VCE(sat) of 1 V at 500 mA/50 mA ensures low conduction loss, but switching speed is limited by fT and Cob; it is not optimized for >100 kHz PWM without external base drive optimization.
What is the thermal resistance junction-to-ambient for KSC2316YTA?
The thermal resistance junction-to-ambient (RθJA) for KSC2316YTA is 130 °C/W, measured on a standard FR-4 PCB (76 mm × 114 mm × 1.57 mm) with minimum land pattern. This value assumes natural convection and no heatsink; actual thermal performance will vary with PCB copper area, airflow, and mounting orientation. Derating begins above 25 °C ambient at 7.2 mW/°C.
