Product details

Overview

2N6520RLRAG from onsemi is a PNP high-voltage bipolar junction transistor (BJT) designed for switching and linear amplification in high-breakdown-voltage applications. It features V_CEO = 350 V, I_C = 500 mA, P_D = 1.5 W at T_C = 25°C, and f_T = 40 MHz, and is commonly used in flyback converter snubber circuits and industrial relay drivers.

For engineers reviewing the 2N6520RLRAG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, TO-92 package details, thermal performance data, switching timing characteristics, and validated alternative parts for high-voltage PNP BJT selection.

Technical Context

The 2N6520RLRAG operates as a general-purpose PNP BJT with negative-polarity voltage and current ratings per datasheet convention. Its DC current gain (h_FE) ranges from 20 to 200 across I_C = 1–100 mA and V_CE = −10 V, and its saturation behavior is characterized by V_CE(sat) ≤ 1.0 V at I_C = 50 mA / I_B = 5 mA.

Thermal design is supported by R_JC = 83.3°C/W and R_JA = 200°C/W, enabling operation from −55°C to +150°C junction temperature. Switching performance includes t_on ≤ 200 ns and t_off ≤ 3.5 µs under specified test conditions (V_CC = −100 V, I_C = 50 mA).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	350 V - Maximum collector-emitter voltage before breakdown; enables use in 300 V-class power supply circuits.
I_C	500 mA - Continuous collector current rating; supports medium-power switching loads without forced cooling.
P_D @ T_C = 25°C	1.5 W - Total device dissipation at case temperature; defines thermal limit when mounted on heatsink.
f_T	40 MHz - Current-gain bandwidth product; confirms suitability for audio-frequency amplification and moderate-speed switching.
V_BE(sat)	0.90 V max at I_C/I_B = 30 - Low base-emitter saturation voltage reduces drive power requirement in saturated-switching designs.
t_off	3.5 µs max - Turn-off time under V_CC = −100 V, I_C = 50 mA; critical for snubber and relay driver timing budgets.
C_eb	100 pF - Emitter-base capacitance at V_EB = −0.5 V; impacts high-frequency input impedance and Miller effect in amplifier stages.

Pinout & Package

2N6520RLRAG is housed in a Pb-free TO-92 (Case 29-11) plastic package with straight leads and tape-and-reel packaging (2000 units/reel). The package measures 4.45–5.20 mm in length, 4.32–5.33 mm in width, and has a lead pitch of 2.54 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink terminal; connects to most positive rail in PNP common-emitter configurations.
2	Base	Control input; requires negative bias relative to emitter to turn on; low I_B max = 250 mA simplifies driver design.
3	Collector	Output terminal; connects to load and negative supply; rated for 350 V reverse blocking capability.

Key Features

Feature	Design Value
High V_CEO rating	350 V enables direct interface with 230 VAC rectified rails and flyback transformer primary-side switching.
Pb-free TO-92 package	Complies with RoHS Directive 2011/65/EU; compatible with standard through-hole reflow and wave soldering processes.
Wide operating temperature	−55°C to +150°C junction range supports deployment in industrial motor controls and outdoor power electronics.
Low V_CE(sat)	≤1.0 V at I_C = 50 mA ensures minimal conduction loss in relay coil and solenoid driver applications.
Controlled C_eb	100 pF at −0.5 V allows predictable frequency response in discrete amplifier stages up to ~10 MHz.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD2955G	V_CEO = 60 V, I_C = 10 A, P_D = 75 W - lower voltage, higher current/power; TO-220 package.	Suitable for high-current, low-voltage linear regulators or motor drivers; not viable for 300+ V circuits.	Select only if application operates below 60 V and requires higher current handling and heatsink mounting.
2N4403	V_CEO = 40 V, I_C = 600 mA, f_T = 200 MHz - much lower voltage rating but higher bandwidth; same TO-92 package.	Used in RF preamps and low-voltage switching; insufficient for mains-derived high-voltage applications.	Choose only for sub-40 V signal amplification where speed matters more than breakdown voltage.

Compared with MJD2955G and 2N4403, the 2N6520RLRAG uniquely balances 350 V breakdown, TO-92 form factor, and 1.5 W dissipation-making it irreplaceable in space-constrained, high-voltage switching roles where neither higher-power nor higher-speed alternatives meet the combined specification envelope.

FAQ

What is the maximum collector-emitter voltage rating for the 2N6520RLRAG?

The 2N6520RLRAG has a guaranteed minimum V_CEO rating of 350 Vdc at I_C = 1.0 mA and I_B = 0, as specified in the "OFF CHARACTERISTICS" section of the official datasheet. This rating applies across the full operating temperature range and defines the absolute maximum reverse-biased voltage the device can block in common-emitter configuration without breakdown.

Is the 2N6520RLRAG RoHS-compliant and lead-free?

Yes, the 2N6520RLRAG is explicitly marked as a Pb-free device in the datasheet, with "Pb−Free Package" noted in the ordering information and marking diagram. It complies with EU RoHS Directive 2011/65/EU and is suitable for lead-free soldering processes including wave and reflow, per onsemi's Soldering and Mounting Techniques Reference Manual.

What is the thermal resistance from junction to case (R_JC) for the 2N6520RLRAG?

The 2N6520RLRAG has a specified R_JC of 83.3°C/W, measured under steady-state conditions at T_C = 25°C. This value is critical for calculating junction temperature rise when the device is mounted to a heatsink and must be used with the actual case temperature-not ambient-to ensure operation remains within the −55°C to +150°C junction limit.

Can the 2N6520RLRAG be used as a direct replacement for the 2N6517 in a circuit?

No-the 2N6520RLRAG is a PNP transistor, while the 2N6517 is an NPN device with identical voltage/current ratings but opposite polarity. Swapping them would invert biasing requirements and likely cause circuit failure. They belong to the same family only in mechanical and rating categories-not functional compatibility.

What are the valid pin assignments for the 2N6520RLRAG in TO-92 package?

The 2N6520RLRAG uses TO-92 Style 2 pinout per the datasheet's mechanical outline: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This is confirmed in the "MECHANICAL CASE OUTLINE" table on page 2, which explicitly lists Style 2 for PNP transistors in this family, distinguishing it from NPN variants like the 2N6515 (Style 17).
