Product details

Overview

MPS8098 from onsemi is an NPN general-purpose amplifier transistor in TO-92 package, rated for 60 V_CEO, 500 mA continuous collector current, and 625 mW power dissipation at T_A = 25°C. It delivers h_FE ≥ 100 at I_C = 1.0 mA and V_CE = 5 V, with f_T = 150 MHz, supporting audio preamplifier, switching, and signal buffering applications.

For engineers reviewing the MPS8098 datasheet, pinout, applications, or equivalent options, key selection criteria include its safe operating area (SOA) up to 60 V/500 mA, low V_CE(sat) of 0.4 V at I_C = 100 mA/I_B = 5 mA, thermal resistance R_JA = 200 °C/W, and compatibility with lead-free assembly per J-STD-020.

Technical Context

The MPS8098 operates as a silicon NPN bipolar junction transistor optimized for linear amplification and medium-speed switching. Its DC current gain (h_FE) is specified across three bias points (1 mA, 10 mA, 100 mA), and its f_T of 150 MHz confirms usable RF capability up to VHF band under small-signal conditions.

Thermal design is constrained by R_JA = 200 °C/W (PCB-mounted) and R_JC = 83.3 °C/W, with second breakdown limiting active-region operation above 60 V and 500 mA per Figure 9. Safe operation requires derating PD by 5.0 mW/°C above 25°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum collector-emitter voltage before breakdown; defines upper rail limit in amplifier or switch designs
I_C (continuous)	500 mA - Sustained output current capacity; supports medium-power driver stages
P_D @ T_A = 25°C	625 mW - Power handling on standard PCB; requires heatsinking or derating above 25°C ambient
h_FE @ I_C = 1 mA	100–300 - Stable DC gain for low-current bias networks and sensor interface amplifiers
f_T	150 MHz - Small-signal bandwidth limit; enables use in FM IF stages and fast-switching logic interfaces
V_CE(sat) @ I_C/I_B = 10	0.4 V - Low saturation voltage reduces conduction loss in switching applications
R_JA	200 °C/W - Thermal resistance to ambient; determines temperature rise under load on typical FR-4 board

Pinout & Package

Package: TO-92 (Case 29-11, Style 1), through-hole, Pb-free compatible. Dimensions per ANSI Y14.5M: body height ~4.7 mm, lead pitch 2.54 mm, E-B-C pin order viewed from flat side.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitter terminal	Reference node for base-emitter junction; connects to ground or low-impedance return path in common-emitter configurations
2 (Base)	Control input	Current-controlled gate; requires series resistor to limit I_B and ensure stable h_FE-based biasing
3 (Collector)	Output terminal	High-side output node; carries full load current and must be routed with adequate copper area for thermal management

Key Features

Feature	Design Value
Lead-free (Pb-free) packaging	Complies with RoHS Directive 2011/65/EU and J-STD-020 reflow profiles without SnPb solder compromise
Wide SOA with second-breakdown protection	Active-region safe operating area extends to 60 V × 500 mA per Figure 9, enabling robust analog and switching use
High f_T / low C_obo	150 MHz gain-bandwidth with only 6.0 pF output capacitance supports stable high-frequency amplification
Low V_BE(on) variation	0.5–0.8 V range across I_C = 1–10 mA ensures predictable turn-on in multi-stage bias networks
Extended temperature range	−55°C to +150°C junction operation supports automotive under-hood and industrial control environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC547B	V_CEO = 45 V, I_C = 100 mA, h_FE = 200–450, f_T ≈ 300 MHz	Lower voltage/current rating; higher gain variability; better for low-power RF, not motor drive	Select when lower power and higher f_T are prioritized over SOA robustness
2N3904	V_CEO = 40 V, I_C = 200 mA, h_FE = 100–300, f_T = 300 MHz	Reduced SOA margin; widely available but unsuitable for >40 V or >200 mA loads	Choose for cost-sensitive consumer electronics where 40 V/200 mA limits are acceptable

Compared with BC547B and 2N3904, the MPS8098 provides superior voltage headroom (60 V), higher continuous current (500 mA), and extended thermal operating range (−55°C to +150°C), making it preferred for industrial switching and ruggedized analog front-ends where reliability under stress is critical.

FAQ

What is the maximum safe collector-emitter voltage for MPS8098?

The MPS8098 has a guaranteed minimum V_(BR)CEO of 60 Vdc at I_C = 10 mA and I_B = 0. This is the absolute maximum DC voltage that can be applied between collector and emitter without risking avalanche breakdown. Designers should maintain at least 20% margin (≤48 V) in continuous operation to ensure long-term reliability under temperature and process variation.

Does MPS8098 support lead-free reflow soldering?

Yes, the MPS8098 is available in Pb-free variants (e.g., MPS8098G) qualified to J-STD-020 moisture sensitivity level (MSL) 1 and compatible with standard lead-free reflow profiles peaking at 260°C. The TO-92 package meets RoHS Directive 2011/65/EU requirements without performance trade-offs.

What is the typical DC current gain (h_FE) of MPS8098 at 100 mA collector current?

At I_C = 100 mA and V_CE = 5.0 Vdc, the MPS8098 exhibits h_FE ≥ 75 (minimum) and typically 100–200. This value is confirmed in the "ON CHARACTERISTICS" table on page 2 of the datasheet and reflects usable gain for medium-current switching and driver stages.

Can MPS8098 replace MPS8099 in a circuit?

No - the MPS8098 and MPS8099 are distinct variants: MPS8098 is rated for 60 V_CEO, while MPS8099 is rated for 80 V_CEO. Substituting MPS8098 for MPS8099 in circuits operating near 80 V risks premature breakdown. They share identical pinout and package, but voltage rating is not interchangeable without redesign.

What thermal derating applies to MPS8098 above 25°C ambient temperature?

The MPS8098 must be derated at 5.0 mW/°C above T_A = 25°C for operation on a standard PCB (R_JA = 200 °C/W). For example, at 75°C ambient, maximum allowable power dissipation drops to 625 mW − (50 × 5.0) = 375 mW. This linear derating ensures junction temperature remains within −55°C to +150°C limits.
