Product details

Overview

50A02CH-TL-H from onsemi is a PNP bipolar junction transistor rated for −50V V_CEO, −500mA continuous collector current, and 700mW power dissipation in the CPH3 surface-mount package; it delivers low V_CE(sat) (−120mV typ. at I_C=−100mA, I_B=−10mA) and high f_T (690MHz), enabling use in high-speed switching and small motor drive circuits.

For engineers reviewing the 50A02CH-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE range (200–500), switching speed (t_on/t_f = 30ns), thermal limits (T_j = 150°C), and Pb-free/Halogen-free compliance per J-STD-609.

Technical Context

This PNP transistor operates with reverse-polarity biasing: emitter is most positive, collector most negative in active/saturation modes. Its high DC current gain (h_FE = 200–500 at I_C = −10mA) supports low-base-drive designs, while 690MHz f_T enables stable amplification up to low-VHF frequencies.

Switching performance is defined by t_on = 30ns, t_stg = 170ns, and t_f = 30ns under specified test conditions; saturation resistance R_CE(sat) is 210mΩ typ. at I_C = −0.5A/I_B = −50mA, confirming suitability for efficient low-voltage switching loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50V - Maximum allowable voltage between collector and emitter with base open; defines safe blocking capability in switching applications.
I_C	−500mA - Continuous DC collector current rating; sets maximum steady-state load current without derating.
V_CE(sat)	−120mV typ. at I_C=−100mA/I_B=−10mA - Low saturation voltage minimizes conduction loss and self-heating in switch-mode operation.
f_T	690MHz - Transition frequency confirms usable gain-bandwidth for RF amplifier stages up to ~100MHz.
h_FE	200–500 at V_CE=−2V, I_C=−10mA - Wide DC gain range allows flexible base resistor design for varying drive strength requirements.
P_C	700mW on ceramic substrate (600mm² × 0.8mm) - Power dissipation limit determines thermal layout requirements and heatsinking necessity.
C_ob	3.8pF at V_CB=−10V, f=1MHz - Output capacitance impacts high-frequency switching efficiency and EMI behavior.

Pinout & Package

50A02CH-TL-H is housed in the CPH3 surface-mount package (JEDEC TO-236AB variant), measuring 2.4mm × 0.95mm × 0.95mm with gull-wing leads. It features a standardized 3-pin configuration optimized for automated placement and reflow soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; requires −10mA typical base current to saturate at −100mA collector load, enabling logic-level drive compatibility.
2	Emitter	Current source node in PNP operation; connected to higher potential rail; must be routed with low-inductance path for fast switching.
3	Collector	Current sink node; carries full load current to ground or lower-potential rail; thermal pad connection recommended for power handling.

Key Features

Feature	Design Value
Low V_CE(sat)	−120mV typ. enables <120mW conduction loss at 100mA, reducing thermal stress in compact layouts.
High f_T	690MHz supports stable small-signal amplification up to VHF band, suitable for IF stages and oscillator buffers.
Fast switching	t_on/t_f = 30ns ensures minimal transition losses in PWM-driven loads like motor windings or LED strings.
Pb-Free & Halogen Free	Complies with J-STD-609 Class 2a and RoHS Directive 2011/65/EU, meeting environmental requirements for industrial and consumer PCBs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT501C-7-F	V_CEO = −50V, I_C = −500mA, but f_T = 250MHz (vs. 690MHz); h_FE min = 200 same, but R_CE(sat) not specified.	Limited to ≤50MHz switching; unsuitable for RF buffer or high-speed PWM above 1MHz.	Select when cost sensitivity outweighs bandwidth need and V_CE(sat) is less critical.
DXT501P-13	V_CEO = −50V, I_C = −600mA, but P_C = 500mW (vs. 700mW); t_on/t_f = 40/40ns (slower than 30/30ns).	Lower power handling and slower edges reduce margin in thermally constrained or >2MHz PWM designs.	Prefer for higher-current DC loads where peak I_C exceeds 500mA but speed and thermal headroom are secondary.

Compared with MMBT501C-7-F and DXT501P-13, the 50A02CH-TL-H provides superior high-frequency response and tighter saturation voltage control, making it optimal for designs requiring both fast edge rates and low conduction loss in space-constrained surface-mount layouts.

FAQ

What is the maximum continuous collector current rating for the 50A02CH-TL-H?

The 50A02CH-TL-H has a maximum continuous collector current (I_C) rating of −500mA at T_a = 25°C. This rating assumes operation within absolute maximum limits and proper PCB thermal management-specifically mounting on a ceramic substrate of 600mm² × 0.8mm thickness. Derating is required above 25°C ambient per the thermal resistance curve in the official datasheet.

Does the 50A02CH-TL-H support high-speed switching applications?

Yes, the 50A02CH-TL-H supports high-speed switching with t_on = 30ns, t_f = 30ns, and t_stg = 170ns under standard test conditions. Its 690MHz f_T and low V_CE(sat) make it suitable for PWM-driven loads operating up to 3MHz, provided layout minimizes parasitic inductance and base drive is adequately sized for required I_B.

What package type does the 50A02CH-TL-H use, and what are its dimensions?

The 50A02CH-TL-H uses the CPH3 surface-mount package (JEDEC TO-236AB), with footprint dimensions of 2.4mm × 0.95mm and height of 0.95mm. Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector. The package is Pb-free and Halogen Free, compliant with J-STD-609 Class 2a and RoHS Directive 2011/65/EU.

How does the 50A02CH-TL-H compare to standard PNP transistors in terms of saturation voltage?

The 50A02CH-TL-H achieves a typical V_CE(sat) of −120mV at I_C = −100mA and I_B = −10mA, and R_CE(sat) of 210mΩ at I_C = −0.5A/I_B = −50mA-significantly lower than many legacy PNP transistors. This reduces conduction loss and self-heating, especially in battery-powered or thermally limited applications.

Is the 50A02CH-TL-H suitable for low-frequency amplifier designs?

Yes, the 50A02CH-TL-H is suitable for low-frequency amplifier designs, with h_FE ranging from 200 to 500 at V_CE = −2V and I_C = −10mA, and f_T = 690MHz. Its low noise characteristics and stable gain make it appropriate for audio preamps, sensor interface stages, and instrumentation amplifiers operating below 1MHz.
