Product details
Overview
2SA2215,LF from Toshiba is a silicon PNP epitaxial transistor designed for high-speed switching in DC-DC converters, strobe circuits, and pulse applications. It delivers hFE = 200–500 at IC = −0.5 A, VCE(sat) ≤ −0.19 V at IC = −1.6 A/IB = −53 mA, and tf = 40 ns (typ.), enabling efficient low-loss switching in compact power stages.
For engineers reviewing the 2SA2215,LF datasheet, 2SA2215,LF pinout, 2SA2215,LF application, or 2SA2215,LF equivalent, key selection criteria include guaranteed VCEO = −20 V, JEITA package code 2-2U1A (UFM), verified switching speed under pulsed IB1/IB2 conditions, and thermal derating guidance for ceramic vs. FR4 mounting.
Technical Context
This PNP bipolar junction transistor operates in common-emitter configuration with fixed base drive control. Its design emphasizes fast turn-off (tf = 40 ns typ.) and low saturation voltage to minimize conduction and switching losses in repetitive pulse-mode operation.
Electrical behavior is characterized across temperature (−55°C to 100°C) and current range (IC = −0.001 A to −1.6 A), with hFE specified at two bias points (IC = −0.5 A and −1.6 A) and VCE(sat)/VBE(sat) validated under matched forced-beta conditions (IC/IB = 30).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20 V: Maximum allowable collector-emitter voltage before breakdown in open-base condition |
| hFE (IC = −0.5 A) | 200–500: Sufficient DC gain to drive moderate base currents with low control overhead |
| VCE(sat) (IC = −1.6 A) | ≤ −0.19 V: Limits conduction loss to < 300 mW at rated pulsed current |
| tf | 40 ns (typ.): Enables >1 MHz switching in non-resonant topologies with controlled fall edge |
| PC (FR4) | 500 mW: Power dissipation limit on standard PCB, defining thermal design margin at Ta = 25°C |
| Tj max | 150°C: Absolute junction temperature ceiling for reliability-limited continuous operation |
Pinout & Package
Package: UFM (JEITA 2-2U1A), surface-mount plastic package with 3-pin single-row layout, 6.6 mg typical weight, footprint 2.1 mm × 1.7 mm × 0.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires −53 mA drive for specified VCE(sat) at IC = −1.6 A |
| 2 | Emitter | Common reference terminal; connected to higher potential rail in PNP high-side switch configurations |
| 3 | Collector | Output current sink; handles −4.0 A pulsed current with defined SOA limits |
Key Features
| Feature | Design Value |
|---|---|
| High hFE range | 200–500 at IC = −0.5 A enables stable biasing with minimal base drive circuitry |
| Low VCE(sat) | ≤ −0.19 V reduces power loss and self-heating during saturated conduction |
| Fast fall time | 40 ns typ. supports clean signal edges in strobe and PWM timing-critical paths |
| Thermally rated PC | 500 mW on FR4 and 800 mW on ceramic board allows layout-dependent power scaling |
Applications
| DC-DC Converter Switch | Camera Strobe Driver |
|---|---|
Use Scenario: Step-down (buck) converter output stage operating at 200–500 kHz with 12 V input and 5 V/2 A output. IC Role / Device Role / Timing Role: PNP high-side switch controlling inductor current flow during active phase. Use Value: Low VCE(sat) minimizes dropout and improves efficiency; fast tf ensures precise duty-cycle control without tailing. | Use Scenario: High-intensity flash discharge circuit triggered by microcontroller GPIO. IC Role / Device Role / Timing Role: Fast-turn-on/-off switch gating capacitor discharge into xenon tube. Use Value: 40 ns tf enables sub-100 μs flash duration; −20 V VCEO safely isolates trigger circuit from HV storage. |
| Industrial Pulse Generator | LED Current Switch |
Use Scenario: Programmable logic-controlled 100 ns–1 ms pulse train for solenoid actuation. IC Role / Device Role / Timing Role: Digital-output interface transistor amplifying FPGA or CPLD drive signals. Use Value: Guaranteed hFE ≥ 200 ensures reliable saturation even with marginal base drive; SOA supports 4 A pulses. | Use Scenario: Constant-current LED string driver with PWM dimming at 1–10 kHz. IC Role / Device Role / Timing Role: Saturated switch modulating LED path between supply and ground. Use Value: −0.19 V VCE(sat) maintains tight current regulation; thermal rating supports 500 mW dissipation on standard PCB. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SA1774,TE85R | VCEO = −30 V, hFE = 120–270, tf = 100 ns (typ.) | Higher voltage rating but slower switching; suited for lower-frequency, higher-voltage rails | Select when VCEO > −20 V is required and switching speed < 1 MHz is acceptable |
| BC807-40,LF | VCEO = −45 V, hFE = 250–630, SOT-23 package, PC = 310 mW | Smaller footprint and higher hFE, but lower power handling and no UFM thermal performance | Choose for space-constrained designs where 500 mW dissipation is not needed |
Compared with 2SA2215,LF, the 2SA1774 offers higher voltage tolerance at the cost of speed, while BC807-40 provides superior gain and miniaturization but sacrifices thermal robustness and pulsed current capability.

FAQ
What is the maximum continuous collector current for 2SA2215,LF?
The 2SA2215,LF has a maximum continuous collector current (IC) of −2.5 A at Ta = 25°C, as defined in its Absolute Maximum Ratings table. This rating assumes proper PCB thermal management per Note 2 (FR4) or Note 1 (ceramic). Exceeding this value risks thermal runaway or accelerated degradation, especially above 25°C ambient.
Does 2SA2215,LF support DC-DC converter topologies beyond buck?
Yes, the 2SA2215,LF is used in buck, boost, and inverting converter configurations where a PNP switch is required-particularly in high-side or level-shifted gate-drive roles. Its −20 V VCEO and low VCE(sat) make it suitable for input voltages up to 12 V, though layout and drive strength must ensure full saturation under load.
How does the UFM package of 2SA2215,LF compare thermally to SOT-23?
The UFM package (2.1 mm × 1.7 mm) of 2SA2215,LF provides significantly better thermal resistance than SOT-23: it achieves 500 mW dissipation on FR4 versus ~310 mW for typical SOT-23 transistors. This is due to larger copper pad area (645 mm²) and optimized leadframe thermal path, directly supporting higher pulsed current operation.
Is 2SA2215,LF RoHS compliant?
Yes, 2SA2215,LF is RoHS compliant per Toshiba's environmental documentation. The ",LF" suffix explicitly denotes lead-free termination and halogen-free molding compound. Compliance aligns with EU Directive 2011/65/EU and subsequent amendments, verified through Toshiba's material declarations and third-party testing.
Can 2SA2215,LF replace 2SA1037 in existing designs?
No-2SA2215,LF is not a direct replacement for 2SA1037. While both are PNP transistors, 2SA1037 has VCEO = −60 V and hFE = 120–270, whereas 2SA2215,LF is rated at −20 V and hFE = 200–500. Substituting 2SA2215,LF in a −60 V application risks breakdown; verify voltage stress, gain matching, and thermal margins before any interchange.
