Product details
Overview
KSA916YTA from onsemi is a PNP epitaxial silicon transistor designed for audio power amplification and driver-stage signal amplification in discrete analog circuits, with −120 V collector–base/collector–emitter breakdown voltage, −800 mA continuous collector current, 900 mW power dissipation at 25°C, 120 MHz current gain bandwidth product, and TO-92 3 LF (Case 135AM) package. It serves as a complement to the NPN KSC2316 in push-pull amplifier stages.
For engineers reviewing the KSA916YTA datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, high-voltage capability (−120 V), medium-power handling (900 mW), DC current gain range (80–240 at IC = −100 mA), and suitability for linear audio output and driver-stage biasing in consumer and industrial analog systems.
Technical Context
This device operates as a general-purpose PNP bipolar junction transistor optimized for linear amplification rather than switching. Its −120 V VCEO/VCBO, 120 MHz fT, and hFE of 80–240 at −100 mA support stable mid-frequency audio gain with low distortion in Class-A or AB configurations.
Thermal design is constrained by RθJA = 130°C/W and RθJC = 41°C/W, requiring careful PCB copper area management for sustained 900 mW operation. The TO-92 3 LF package mandates lead-formed mounting with defined land pattern per onsemi's mechanical outline (Case 135AM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −120 V: Supports rail-to-rail operation in ±60 V supply audio stages without breakdown. |
| IC | −800 mA: Enables drive capability for small-signal speaker loads or pre-driver stages. |
| PD | 900 mW at 25°C: Requires thermal derating (7.2 mW/°C) above ambient; limits continuous output power in compact enclosures. |
| fT | 120 MHz: Ensures adequate gain margin up to upper-audio frequencies (20 kHz) with stable phase response. |
| hFE | 80–240 at −100 mA: Provides predictable DC bias stability across production lots for fixed-bias or emitter-degenerated designs. |
| VCE(sat) | ≤ −1 V at −500 mA/−50 mA: Minimizes conduction loss in saturated driver applications, reducing heat generation. |
| Cob | 40 pF at −10 V: Limits high-frequency Miller effect in common-emitter gain stages, aiding stability. |
Pinout & Package
Package: TO-92 3 LF (Case 135AM), lead-formed, Pb-free, through-hole mounting. Dimensions: 8.0 mm × 4.9 mm × 3.6 mm (L × W × H), with standardized land pattern per onsemi mechanical drawing 98AON14058G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP operation | Connected to positive rail in common-emitter configuration; dictates current sourcing direction and bias polarity. |
| 2 (Collector) | Current sink terminal | Typically tied to load (e.g., transformer primary or speaker coil); voltage swing limited to −120 V max. |
| 3 (Base) | Control input for minority-carrier injection | Receives forward-biased current (IB) to modulate IC; requires series resistor to limit drive and prevent saturation overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage PNP structure | −120 V VCEO/VCBO enables use in high-supply-voltage analog stages where NPN complements are unavailable. |
| Audio-optimized fT | 120 MHz gain-bandwidth supports flat frequency response up to 100 kHz, minimizing phase shift in feedback loops. |
| Controlled hFE classification | Y-grade bin (hFE2 = 120–240) ensures tighter DC bias spread for predictable quiescent current in production amplifiers. |
| Low VCE(sat) | ≤ −1 V at high current reduces power loss and thermal stress during peak output conditions. |
| TO-92 Pb-free packaging | Meets RoHS compliance without compromising thermal resistance (RθJC = 41°C/W) or mechanical reliability. |
Applications
| Hi-Fi Audio Preamp Stage | DC Motor Driver Interface |
|---|---|
Use Scenario: Low-noise voltage amplification in the second stage of a two-stage line-level amplifier before power output. IC Role / Device Role / Timing Role: PNP transistor configured in common-emitter mode to provide inverted gain with high input impedance and low output impedance. Use Value: −120 V rating allows operation from ±48 V rails; 120 MHz fT preserves transient fidelity across 20 Hz–20 kHz bandwidth. | Use Scenario: Bidirectional H-bridge half-bridge control using complementary PNP/NPN pairs to drive small brushed DC motors (≤12 V, ≤500 mA). IC Role / Device Role / Timing Role: High-side PNP switch providing current sourcing to motor terminal during forward drive phase. Use Value: −800 mA IC and ≤−1 V VCE(sat) minimize conduction loss; TO-92 form factor simplifies manual prototyping and low-volume assembly. |
| Industrial Sensor Signal Conditioning | Legacy CRT Display Deflection Driver |
Use Scenario: Amplifying low-level thermocouple or strain gauge signals in isolated industrial transmitters operating at elevated ambient temperatures. IC Role / Device Role / Timing Role: Discrete PNP emitter-follower buffer delivering low-output-impedance drive to ADC input while rejecting common-mode noise. Use Value: 150°C maximum junction temperature and −5 V VEBO ensure robustness against ESD and overvoltage transients near sensor nodes. | Use Scenario: Horizontal deflection yoke driver in legacy monochrome CRT monitors requiring fast current slew and high-voltage swing. IC Role / Device Role / Timing Role: PNP transistor in grounded-base configuration to deliver high di/dt current pulses into inductive yoke windings. Use Value: 120 MHz fT and 40 pF Cob enable clean square-wave edge response up to 15.734 kHz line frequency without ringing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA92 | Lower IC (−500 mA), lower fT (50 MHz), same −300 V VCEO | Better suited for high-voltage, low-current switching (e.g., relay drivers); insufficient fT for wideband audio. | Select MPSA92 only when voltage >120 V is required and bandwidth <50 kHz is acceptable. |
| KSA1220Y | Higher IC (−1.5 A), higher PD (1.5 W), same −120 V rating and TO-92 package | Supports higher continuous output power in driver stages but requires larger heatsinking due to increased dissipation. | Choose KSA1220Y when sustained >900 mW operation is needed and board space permits enhanced thermal relief. |
Compared with MPSA92 and KSA1220Y, the KSA916YTA delivers optimal balance of audio-grade bandwidth (120 MHz), medium-power handling (900 mW), and precise hFE grading-making it preferred for cost-sensitive, high-fidelity linear amplification where both speed and thermal manageability matter.

FAQ
What is the maximum safe collector–emitter voltage for KSA916YTA?
The KSA916YTA has a guaranteed minimum VCEO of −120 V at IC = −10 mA and TA = 25°C. Operation beyond this rating risks irreversible junction breakdown. Derating is not specified above 25°C for VCEO, so design margins must be applied based on worst-case ambient and thermal conditions. Always verify actual circuit voltage transients with oscilloscope measurements before finalizing the KSA916YTA design.
Is KSA916YTA pin-compatible with KSC2316?
No, the KSA916YTA is not pin-compatible with the KSC2316. While they are complementary devices (PNP vs. NPN), their pinouts differ: KSA916YTA uses Emitter–Collector–Base (1–2–3), whereas KSC2316 uses Emitter–Base–Collector (1–2–3). Swapping them without board revision will cause circuit failure. Always consult the respective marking diagrams and mechanical outlines before layout integration of the KSA916YTA.
What does the 'Y' suffix in KSA916YTA indicate?
The 'Y' in KSA916YTA denotes the hFE classification grade per onsemi's datasheet: hFE2 = 120–240 at VCE = −5 V and IC = −100 mA. This tighter gain bin improves predictability in bias-critical applications like Class-A amplifiers. The full part number KSA916YTA also confirms Pb-free TO-92 3 LF packaging (Case 135AM), distinguishing it from older leaded variants.
Can KSA916YTA be used in switching applications?
Yes, the KSA916YTA can operate in switching mode, but it is optimized for linear amplification. Its VCE(sat) ≤ −1 V at −500 mA/−50 mA and fT = 120 MHz support moderate-speed switching (≤100 kHz), though storage time and fall time are not characterized in the datasheet. For dedicated switching, consider faster-optimized PNP transistors; for the KSA916YTA, prioritize linear gain stability and thermal behavior.
What is the thermal resistance from junction to case (RθJC) for KSA916YTA?
The KSA916YTA has a specified RθJC of 41°C/W, measured under standard test conditions (TC = 25°C, mounted on a defined copper pad). This value enables accurate junction temperature estimation when heatsinking is applied directly to the case (e.g., via screw-mount clip). When using PCB copper alone, rely on RθJA = 130°C/W and apply derating (7.2 mW/°C) above 25°C ambient for the KSA916YTA.
