Product details

Overview

2SB1215T-H from onsemi is a PNP bipolar junction transistor rated for –100 V V_CEO, –3 A I_C, and low V_CE(sat) of –400 mV at –1.5 A/–0.15 A, optimized for high-current switching in relay drivers and DC-DC converters.

For engineers reviewing the 2SB1215T-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, TP package mechanical compatibility, guaranteed halogen-free compliance, and confirmed f_T ≥ 130 MHz performance under V_CE = –10 V / I_C = –0.5 A conditions.

Technical Context

This device operates as a single PNP switch with symmetrical dual-collector configuration (pins 2 and 4 both connected to collector), enabling robust current handling and thermal distribution in high-power linear and switching topologies.

Its design supports fast switching (t_on = 100 ns, t_f = 50 ns) and stable DC gain linearity (h_FE = 140–400 across I_C = –0.5 A to –2 A), with junction temperature limited to 150°C and storage range spanning –55°C to +150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–100 V: Maximum safe collector-emitter voltage before breakdown under open-base condition.
I_C	–3 A: Continuous DC collector current rating at T_c = 25°C, defining steady-state power switching capability.
V_CE(sat)	–400 mV max at I_C = –1.5 A / I_B = –0.15 A: Low saturation voltage minimizes conduction loss in saturated-switch applications.
f_T	130–180 MHz: Gain-bandwidth product ensures usable high-frequency amplification or RF switching up to ~100 MHz.
h_FE	140–400: DC current gain range across operating currents, supporting predictable base drive sizing for diverse load conditions.
P_C	20 W at T_c = 25°C: Case-referenced power dissipation limit, requiring heatsinking for sustained >1 W operation.
C_ob	25 pF max at V_CB = –10 V: Output capacitance impacts switching speed and EMI in hard-switched circuits.

Pinout & Package

Package: TP (JEITA SC-64 / JEDEC TO-251), surface-mount, 4-pin leadframe with exposed collector pads (pins 2 and 4), 0.315 g mass, 7.0 mm × 5.0 mm footprint.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; requires –0.15 A base current to saturate at –1.5 A collector load.
2	Collector	Main high-current output path; electrically tied to pin 4 for parallel current sharing and thermal spreading.
3	Emitter	Common reference terminal; connected to system ground or negative rail in PNP high-side switch configurations.
4	Collector	Redundant collector connection; must be soldered to same copper pour as pin 2 for rated current and thermal performance.

Key Features

Feature	Design Value
Low V_CE(sat)	–400 mV max enables <1.5 W conduction loss at –1.5 A, reducing heatsink requirements in compact converters.
High f_T	≥130 MHz supports clean square-wave switching up to 20–30 MHz in Class C or resonant topologies.
Dual-collector layout	Pins 2 and 4 provide 2× current-carrying capacity and lower thermal resistance vs. single-pin packages.
Halogen-free construction	Complies with IEC 61249-2-21, eliminating brominated flame retardants for RoHS-compliant end-product certification.
Linear h_FE response	Stable gain across I_C = –0.5 A to –2 A simplifies analog amplifier biasing and improves current-source accuracy.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	TO-252 (DPAK) package, V_CEO = –100 V, I_C = –2 A, V_CE(sat) = –500 mV @ –1 A	Lower current rating and higher saturation voltage reduce efficiency in >2 A loads	Select when DPAK footprint is required and peak current ≤ 2 A
2SA1943	TO-3P package, V_CEO = –230 V, I_C = –15 A, V_CE(sat) = –1.5 V @ –8 A	Larger thermal mass and higher V_CE(sat) increase board area and conduction loss	Select only for >100 V or >5 A applications where TP footprint is insufficient

Compared with MJD127G and 2SA1943, the 2SB1215T-H delivers optimal balance of low V_CE(sat), compact TP packaging, and verified 3 A continuous rating-making it preferred for space-constrained, medium-power PNP switching where thermal management and PCB real estate are critical.

FAQ

What is the package type and lead count for 2SB1215T-H?

The 2SB1215T-H uses the TP package (JEITA SC-64 / JEDEC TO-251), a 4-pin surface-mount outline with dual collector terminals (pins 2 and 4), base (pin 1), and emitter (pin 3). Its 7.0 mm × 5.0 mm footprint and 0.315 g mass support high-density PCB layouts while maintaining 20 W thermal capability at T_c = 25°C. The 2SB1215T-H is not offered in TO-220 or SOT-23 variants.

Is 2SB1215T-H halogen-free and RoHS compliant?

Yes, the 2SB1215T-H is explicitly marked "Pb Free and Halogen Free" in the official onsemi ordering information, meeting IEC 61249-2-21 and EU RoHS Directive 2011/65/EU requirements. This applies to all materials-including molding compound, leadframe, and internal die attach-ensuring full compliance for export-controlled and environmentally regulated end products.

What is the guaranteed minimum h_FE for 2SB1215T-H at I_C = –0.5 A?

The 2SB1215T-H has a guaranteed minimum h_FE of 140 at V_CE = –5 V and I_C = –0.5 A, per the "Rank S" classification defined in the datasheet. This value is tested and binned during manufacturing; units labeled "T" offer h_FE = 200–400 under identical conditions. The 2SB1215T-H falls under Rank T per its part number suffix "T".

Can 2SB1215T-H be used as a direct replacement for 2SB1215S-H?

No-2SB1215T-H and 2SB1215S-H share identical electrical specifications and TP packaging but differ in h_FE binning: "S" denotes h_FE = 140–280, while "T" guarantees h_FE = 200–400. Substituting one for the other may affect base drive design and current regulation accuracy, especially in linear amplifier or precision current mirror applications using the 2SB1215T-H.

What is the maximum allowable pulse current for 2SB1215T-H?

The 2SB1215T-H supports a maximum collector current pulse (I_CP) of –6 A, specified under short-duration, non-repetitive conditions per the Absolute Maximum Ratings table. This rating assumes T_j ≤ 150°C and proper PCB copper area for transient heat dissipation; sustained operation above –3 A requires active thermal management and is not recommended for continuous duty.
