Product details
Overview
MCH6203-TL-E from onsemi is a PNP bipolar junction transistor in MCPH6 (SC-88/SC-70-6/SOT-363) package, rated for −50 V VCEO, −1 A IC, and 1.0 W power dissipation at Ta = 25°C on ceramic substrate. It delivers low VCE(sat) of −145 mV (typ) at IC = −300 mA / IB = −6 mA and high-speed switching with ton = 38 ns, used in compact relay and lamp driver circuits.
For engineers reviewing the MCH6203-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include confirmed PNP polarity, verified −50 V breakdown rating, validated 420 MHz fT, documented MCPH6 package footprint, and measured VCE(sat) performance under pulsed and DC conditions.
Technical Context
The MCH6203-TL-E is a discrete PNP BJT optimized for medium-current switching in space-constrained applications. Its electrical behavior is defined by VCEO = −50 V, IC = −1.0 A continuous, and fT = 420 MHz - confirming suitability for high-frequency digital switching rather than linear amplification.
Thermal design relies on its 1.0 W power dissipation capability when mounted on a 600 mm² × 0.8 mm ceramic substrate, and its junction temperature limit of 150°C ensures robustness in industrial ambient conditions up to 75°C, as validated by derating curves in the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage before breakdown in open-base configuration |
| IC (cont.) | −1.0 A - continuous collector current rating defining steady-state load drive capability |
| VCE(sat) @ IC/IB = −300 mA/−6 mA | −145 mV (typ) - low saturation voltage enabling <0.5 W conduction loss in switching applications |
| fT | 420 MHz - gain-bandwidth product confirming usable switching speeds up to ~100 MHz square-wave operation |
| hFE @ VCE = −2 V, IC = −100 mA | 200–560 - DC current gain range supporting reliable base drive design across production lots |
| PC @ Ta = 25°C | 1.0 W - thermal power handling on specified ceramic substrate, critical for PCB layout and heatsinking decisions |
| ton/tf | 38 ns / 40 ns - fast turn-on and fall times enabling sub-100 ns pulse control in digital logic interfaces |
Pinout & Package
MCH6203-TL-E uses the MCPH6 surface-mount package (JEITA SC-88 / JEDEC SC-70-6 / SOT-363), measuring 2.1 mm × 1.6 mm × 0.85 mm height, with lead pitch of 0.65 mm and Pb-free termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector | Four parallel collector terminals reduce bond wire resistance and improve current sharing and thermal spreading |
| 3 | Base | Sole base connection for bias control; requires current-limited drive due to hFE-dependent IB needs |
| 4 | Emiter | Single emitter terminal - primary current return path; layout must minimize trace inductance for fast switching |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −145 mV (typ) at IC = −300 mA enables <0.05 V headroom in 3.3 V or 5 V rail-switching designs |
| High-speed switching | ton = 38 ns and tf = 40 ns support >5 MHz digital control without significant delay skew |
| Ultrasmall footprint | MCPH6 package (2.1 × 1.6 mm) reduces board area by ~50% vs. SOT-23 while maintaining 1 A capability |
| High power dissipation | 1.0 W rating on ceramic substrate allows sustained operation at full IC without external heatsink |
| MBIT process technology | Enables tight parameter distribution (e.g., hFE 200–560) and stable performance across −25°C to +75°C ambient |
Applications
| Relay Driver Circuit | Lamp Driver Module |
|---|---|
Use Scenario: Driving 12 V, 500 mA electromagnetic relay coils in industrial PLC output stages. IC Role / Device Role / Timing Role: PNP switch sinking coil current during deactivation; operates in saturation with forced β = 50. Use Value: Low VCE(sat) minimizes coil voltage drop, ensuring reliable relay release; four-collector layout improves thermal margin during repeated actuation. | Use Scenario: Controlling LED arrays or incandescent indicator lamps in automotive dashboard modules. IC Role / Device Role / Timing Role: High-side current sink for common-anode LED strings, switched via microcontroller GPIO. Use Value: Fast tf = 40 ns eliminates visible flicker in PWM-dimmed lamps; ultrasmall MCPH6 footprint saves space in dense instrument cluster PCBs. |
| Motor Driver Stage | Flash Circuit for Camera Modules |
Use Scenario: Half-bridge high-side switch in 5 V brushed DC motor drivers for portable medical pumps. IC Role / Device Role / Timing Role: PNP transistor providing controlled turn-off of motor current path during PWM dead-time. Use Value: Confirmed 420 MHz fT supports clean edge integrity at 20 kHz PWM; 150°C Tj rating accommodates sealed enclosure thermal buildup. | Use Scenario: Triggering xenon flash tubes in compact camera modules requiring precise high-voltage pulse timing. IC Role / Device Role / Timing Role: Fast-switching PNP switch discharging storage capacitor into flash tube primary winding. Use Value: ton = 38 ns ensures sub-100 ns trigger jitter; −50 V VCEO withstands flyback transients up to 40 V during tube ionization. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP bipolar switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT6427LT1G | VCEO = −60 V, IC = −1.0 A, VCE(sat) = −200 mV (typ) @ −500 mA, SOT-23 package | Higher voltage rating but higher saturation voltage and larger footprint; no multi-collector configuration | Select when >−50 V breakdown margin is required and board space permits SOT-23 |
| PN2907A | VCEO = −60 V, IC = −600 mA, VCE(sat) = −1.6 V (max) @ −500 mA, TO-92 through-hole | Lower current rating, much higher VCE(sat), and through-hole mounting incompatible with automated SMT assembly | Select only for legacy through-hole prototyping where thermal mass and manual assembly are acceptable |
Compared with MCH6203-TL-E, MMBT6427LT1G offers greater voltage headroom but sacrifices saturation efficiency and miniaturization; PN2907A provides no viable SMT alternative and cannot match the 1 A/420 MHz/0.85 mm-height combination delivered by MCH6203-TL-E in modern compact designs.

FAQ
What is the polarity and transistor type of MCH6203-TL-E?
MCH6203-TL-E is a PNP bipolar junction transistor. This is explicitly confirmed in the official datasheet title ("Bipolar Transistor (–)50V, (–)1A, Low VCE(sat), (PNP)NPN Single MCPH6") and reinforced by all absolute maximum ratings and electrical characteristics using negative polarity notation (e.g., VCEO = −50 V, IC = −1.0 A). The MCH6203-TL-E variant is the PNP device in the dual-part MCH6103/MCH6203 series.
What package does MCH6203-TL-E use and what are its key mechanical dimensions?
MCH6203-TL-E uses the MCPH6 package, which is equivalent to JEITA SC-88, JEDEC SC-70-6, and SOT-363. Its dimensions are 2.1 mm length × 1.6 mm width × 0.85 mm maximum height, with 0.65 mm lead pitch and six terminals. The official outline drawing and land pattern example confirm this geometry, and the "TL" in the part number denotes embossed tape-and-reel packaging (3,000 pcs./reel).
What is the maximum continuous collector current rating for MCH6203-TL-E and under what conditions?
The maximum continuous collector current for MCH6203-TL-E is −1.0 A, specified at Ta = 25°C with the device mounted on a 600 mm² × 0.8 mm ceramic substrate. This rating is distinct from the −3 A pulsed current (ICP) and is thermally limited - the datasheet's PC vs. Ta curve shows derating begins immediately above 25°C ambient, requiring careful thermal design in real-world MCH6203-TL-E implementations.
Does MCH6203-TL-E have a single collector or multiple collector terminals, and why does it matter?
MCH6203-TL-E has four collector terminals (pins 1, 2, 5, and 6), as shown in the "Electrical Connection" diagram and "Marking" section of the datasheet. This multi-collector configuration lowers effective on-resistance and improves current sharing and thermal spreading - directly enabling its 1.0 W power dissipation rating and reliability in high-duty-cycle switching applications using the MCH6203-TL-E.
What is the typical gain-bandwidth product (fT) of MCH6203-TL-E and how is it measured?
The typical gain-bandwidth product (fT) of MCH6203-TL-E is 420 MHz, measured at VCE = −10 V and IC = −300 mA per the "Electrical Characteristics" table. This value is confirmed in the fT vs. IC graph (IT01905) for MCH6203, showing 420 MHz at the specified test condition - a key metric validating the MCH6203-TL-E's suitability for high-speed digital switching above 50 MHz.
