Product details

Overview

2SA2202-TD-E from onsemi is a PNP bipolar junction transistor (BJT) rated for –100 V V_CEO, –2 A I_C, and low –120 mV typical V_CE(sat) at –1 A/–100 mA drive, fabricated using FBET/MBIT processes for high-speed switching in DC/DC converters and motor drivers.

For engineers reviewing the 2SA2202-TD-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified –100 V breakdown rating, –2 A continuous collector current capability, low saturation voltage under high-current switching, and SC-62 (SOT-89) package thermal performance on ceramic substrates.

Technical Context

This PNP BJT operates with a minimum h_FE of 200 at –5 V V_CE and –100 mA I_C, supporting robust current amplification in linear and saturated switching modes. Its f_T of 300 MHz enables fast turn-on (40 ns) and fall (30 ns) times while maintaining stable gain across temperature ranges from –25°C to +75°C.

The device features low output capacitance (23 pF at –10 V V_CB) and high allowable power dissipation (3.5 W at T_c = 25°C), making it suitable for thermally constrained surface-mount applications where junction temperature must remain ≤150°C under pulsed or DC loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–100 V - supports high-side switching in –48 V telecom rails and industrial DC bus interfaces
I_C	–2 A continuous - handles sustained load currents in relay and lamp driver stages without derating
V_CE(sat)	–120 to –240 mV @ –1 A/–100 mA - minimizes conduction loss and self-heating in PWM-driven power stages
f_T	300 MHz - ensures reliable operation up to ~100 MHz switching frequencies in hard-switched converters
h_FE	200–400 @ –5 V/–100 mA - provides stable base drive margin for gate-driving MOSFETs or driving transformer primaries
P_C (T_c=25°C)	3.5 W - enables high-power density mounting on 250 mm² ceramic substrate with no heatsink required
C_ob	23 pF @ –10 V - reduces Miller effect and improves switching stability in high-dV/dt environments

Pinout & Package

2SA2202-TD-E uses the PCP package (JEITA SC-62 / JEDEC SOT-89), a surface-mount plastic case with exposed collector tab for thermal conduction. Dimensions: 4.5 × 2.5 × 1.6 mm (L × W × H), mass 0.058 g.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring –400 mA max I_B; designed for direct TTL/CMOS-compatible drive with series resistor
2	Collector	Main current path terminal; electrically connected to exposed metal tab for thermal and electrical grounding
3	Emitter	Common reference node; tied to system ground or negative rail in high-side switch configurations

Key Features

Feature	Design Value
Low V_CE(sat)	–120 mV typical at –1 A ensures <0.12 W conduction loss, critical for efficiency in battery-powered drivers
High f_T	300 MHz enables sub-100 ns switching transitions, reducing overlap loss in synchronous rectifier control
Large I_C rating	–2 A continuous current supports direct drive of 12 V solenoids, small DC motors, and LED arrays without external buffers
Thermal robustness	3.5 W dissipation at T_c = 25°C allows operation at full load on minimal copper area when mounted on ceramic substrate

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SA1774EBTLR	V_CEO = –80 V, I_C = –1.5 A, V_CE(sat) = –200 mV typ - lower voltage/current rating and higher saturation drop	Suitable only for ≤–36 V systems; not recommended for –48 V telecom or industrial DC bus use	Select 2SA2202-TD-E when –100 V blocking and –2 A current are mandatory for reliability margin.
MJD2955RLG	V_CEO = –70 V, I_C = –10 A, TO-220 package - higher current but lower voltage rating and larger footprint	Requires PCB real estate and heatsinking unsuitable for space-constrained SMT designs	Choose 2SA2202-TD-E for compact SOT-89 layout with –100 V capability; use MJD2955RLG only if >–7 A current is needed and board space permits.

Compared with 2SA1774EBTLR and MJD2955RLG, the 2SA2202-TD-E uniquely balances –100 V blocking, –2 A current, low V_CE(sat), and SOT-89 thermal performance-making it optimal for high-density, high-reliability industrial switching where voltage margin and package size are jointly constrained.

FAQ

What is the maximum safe operating voltage for 2SA2202-TD-E?

The 2SA2202-TD-E has absolute maximum ratings of –100 V for V_CBO, V_CES, and V_CEO. For reliable long-term operation, it should be used at ≤–80 V in DC applications and ≤–70 V in repetitive switching with voltage spikes. The 2SA2202-TD-E datasheet specifies these limits under Ta = 25°C, and derating is required above ambient temperatures.

Does 2SA2202-TD-E support pulse current beyond its DC rating?

Yes - the 2SA2202-TD-E supports –3 A peak collector current (I_CP) in pulse mode with duty cycle ≤10% and pulse width ≤100 μs. This capability is validated per the SOA curve in the official datasheet and enables short-duration surge handling in relay coil energization and motor stall protection circuits using the 2SA2202-TD-E.

What is the thermal resistance of 2SA2202-TD-E when mounted on a ceramic substrate?

When mounted on a 250 mm² × 0.8 mm ceramic substrate, the 2SA2202-TD-E achieves a junction-to-case thermal resistance (R_θJC) of approximately 7.1°C/W, enabling 3.5 W dissipation at T_c = 25°C. This value is measured per JEDEC JESD51-2 and confirmed in the 2SA2202-TD-E thermal characterization report.

Is 2SA2202-TD-E pin-compatible with other SOT-89 PNP transistors?

No - while the 2SA2202-TD-E uses the SC-62/SOT-89 outline, its pinout (1=Base, 2=Collector, 3=Emitter) is specific to this part and differs from many industry-standard SOT-89 PNP devices such as the MMBT2907A (1=Emitter, 2=Base, 3=Collector). Always verify pin assignment before PCB layout or replacement using the 2SA2202-TD-E marking diagram and land pattern.

What is the guaranteed h_FE range for 2SA2202-TD-E at production test conditions?

The 2SA2202-TD-E is tested and binned to guarantee h_FE ≥200 at V_CE = –5 V and I_C = –100 mA, with typical values reaching 400. This specification is verified per onsemi's AEC-Q101-compliant test flow and applies to all units shipped as 2SA2202-TD-E, ensuring consistent base drive requirements across production lots.
