Product details
Overview
2SC6135,LF from Toshiba Electronic Devices & Storage Corporation is a silicon NPN epitaxial transistor designed for high-speed switching in DC-DC converters and strobe circuits. It delivers hFE = 400–1000 at IC = 0.1 A, VCE(sat) ≤ 0.12 V (IC = 300 mA, IB = 6 mA), and tf = 85 ns (typ.), enabling efficient low-loss switching in compact power stages.
For engineers reviewing the 2SC6135,LF datasheet, 2SC6135,LF pinout, 2SC6135,LF application, or 2SC6135,LF equivalent, key selection criteria include its 50 V VCEO rating, 1.0 A continuous collector current, UFM package with confirmed 3-pin leaded configuration, and verified performance in pulse-driven lighting and SMPS control stages.
Technical Context
This transistor operates in common-emitter configuration with fixed bias-driven switching behavior. Its low VCE(sat) and fast tf/tr/tstg timing (tf = 85 ns, tr = 35 ns, tstg = 680 ns) support high-duty-cycle, low-loss operation in flyback and boost converter primary-side switches.
Designed for discrete BJT-based topologies, it relies on external base drive for saturation control and exhibits strong hFE stability across IC = 0.1–0.3 A and temperatures up to 100°C, as confirmed by published IC–hFE and VCE(sat)–IC curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base conditions; defines upper limit for switch node voltage swing in DC-DC applications. |
| IC (DC) | 1.0 A - Continuous collector current handling capacity; supports ≥1 W switching loads with appropriate heatsinking on FR4. |
| hFE (IC = 0.1 A) | 400–1000 - High DC current gain enables low base drive current (e.g., ~0.1–0.25 mA) for 100 mA collector load. |
| VCE(sat) | ≤0.12 V @ IC = 300 mA, IB = 6 mA - Minimizes conduction loss in saturated-switch mode; contributes to <36 mW static loss at 300 mA. |
| tf | 85 ns (typ.) - Fall time measured under VCC ≈ 30 V, RL = 100 Ω; enables >1 MHz switching in optimized driver layouts. |
| Cob | 5 pF @ VCB = 10 V - Low output capacitance reduces Miller-effect delay and improves turn-off speed in high-frequency switching. |
Pinout & Package
Supplied in the UFM (2-2U1A) surface-mount package: 3-pin, single-row, gull-wing leads, 2.1 mm × 1.7 mm footprint, 0.65 mm pitch, 0.7 mm height, 6.6 mg typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal accepting DC or pulsed current to drive transistor into saturation or cutoff; requires series resistor for current limiting. |
| 2 | Emitter | Current return path; connected to ground or low-side reference in common-emitter configurations; carries full load current. |
| 3 | Collector | High-side switching node; connects to inductive load or switching rail; must withstand VCEO and handle peak current surges. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE range | 400–1000 at IC = 0.1 A ensures consistent saturation with minimal base drive overhead across production lots. |
| Low VCE(sat) | ≤0.12 V reduces conduction losses below 36 mW at 300 mA, improving thermal margin in space-constrained DC-DC modules. |
| Fast switching | tf = 85 ns and tr = 35 ns enable clean edge transitions in strobe flash timing and PWM-controlled power stages. |
| Robust voltage ratings | VCBO = 100 V and VCEO = 50 V support use in 24–48 V input systems with transient margin for inductive kickback. |
Applications
| Strobe Lighting Control | DC-DC Converter Switch |
|---|---|
Use Scenario: Driving xenon or high-intensity LED flash tubes in camera modules and emergency beacons. IC Role / Device Role / Timing Role: NPN switch controlling high-current discharge pulse through flash capacitor; triggered by microcontroller GPIO. Use Value: Fast tf/tr and low VCE(sat) ensure precise sub-millisecond flash duration and minimal energy loss during pulse delivery. | Use Scenario: Low-side switching element in non-synchronous buck or boost converter power stages. IC Role / Device Role / Timing Role: Discrete main switch turning inductor current on/off at 100 kHz–1 MHz; driven by PWM controller via base resistor network. Use Value: High hFE allows direct MCU-level drive without buffer stage; 50 V VCEO safely handles 36 V input transients. |
| Industrial Sensor Interface | Relay Driver Circuit |
Use Scenario: Level-shifting and current amplification for digital outputs driving optocouplers or isolated logic inputs. IC Role / Device Role / Timing Role: Signal-conditioning transistor translating 3.3 V/5 V logic to 12–24 V interface levels with galvanic isolation. Use Value: Stable hFE over temperature ensures reliable logic translation across -40°C to +85°C industrial ambient ranges. | Use Scenario: Driving electromagnetic relay coils rated up to 1 A in PLC I/O modules and HVAC controllers. IC Role / Device Role / Timing Role: Saturated switch providing full coil current while clamping inductive flyback with external diode. Use Value: Low VCE(sat) limits self-heating during continuous duty; 1.0 A IC rating matches standard 12 V/24 V relay coil requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC5662,LF | VCEO = 60 V, hFE = 350–800, tf = 100 ns, same UFM package | Higher voltage margin but slower fall time; suitable where 60 V headroom is critical | Prefer when operating near 48 V rails with significant transients |
| MMBT4401LT1G | VCEO = 40 V, hFE = 100–300, SOT-23 package, lower power dissipation (225 mW) | Lower voltage/current capability; not drop-in due to different package and gain profile | Select only for low-power signal switching where 500 mW PC is sufficient |
Compared with 2SC6135,LF, the 2SC5662,LF offers higher VCEO but slower switching, while MMBT4401LT1G provides SOT-23 compatibility at reduced voltage and gain-neither is pin-compatible, and both require layout and drive circuit review for substitution.

FAQ
What is the maximum continuous collector current rating for the 2SC6135,LF?
The 2SC6135,LF has a maximum continuous collector current (IC) rating of 1.0 A at Ta = 25°C when mounted on an FR4 board (Note 2). Derating applies above 25°C ambient; at 70°C, usable IC drops to approximately 0.7 A per published thermal resistance data. This rating directly determines its suitability for 1 A-class switching loads in the 2SC6135,LF design.
Does the 2SC6135,LF have a documented RoHS compliance status?
Yes, the 2SC6135,LF is RoHS compliant per Toshiba's environmental documentation. The ",LF" suffix explicitly denotes lead-free termination and halogen-free packaging. Compliance aligns with EU Directive 2011/65/EU and Toshiba's internal substance control standards, confirmed in official Toshiba product change notices and material declarations for the 2SC6135,LF.
What is the base-emitter saturation voltage specification for the 2SC6135,LF?
The 2SC6135,LF has a maximum base-emitter saturation voltage (VBE(sat)) of 1.10 V under test conditions of IC = 300 mA and IB = 6 mA. This value reflects the forward voltage required to fully saturate the base junction and is critical for calculating base resistor values in driver circuits using the 2SC6135,LF.
Can the 2SC6135,LF be used in linear amplifier applications?
No-the 2SC6135,LF is characterized and qualified exclusively for switching operation. Toshiba's datasheet specifies parameters like hFE only at defined switching bias points (e.g., VCE = 2 V, IC = 0.1 A), and does not provide small-signal parameters (e.g., fT, hfe, or noise figure) needed for linear amplification. Use of the 2SC6135,LF outside switching contexts is not supported.
What is the junction-to-ambient thermal resistance (RθJA) for the 2SC6135,LF on FR4?
For the 2SC6135,LF mounted on a standard FR4 board (25.4 mm × 25.4 mm × 1.6 mm, Cu pad = 645 mm²), RθJA is 250°C/W, derived from PC = 500 mW and ΔT = 125°C (150°C max Tj – 25°C ambient). This value governs thermal design margins and must be applied when estimating junction temperature rise in actual 2SC6135,LF deployments.
