Product details
Overview
BC68-25PA from Nexperia is a 20 V, 2 A NPN medium-power transistor in a thermally enhanced DFN2020-3 (SOT1061) leadless SMD package, designed for linear voltage regulation, MOSFET gate driving, and low-side switching. It delivers hFE = 160–375 at VCE = 1 V and IC = 500 mA, supports 3 A peak collector current, and features an exposed heatsink for improved thermal conduction in space-constrained power stages.
For engineers reviewing the BC68-25PA datasheet, BC68-25PA pinout, BC68-25PA application, or BC68-25PA equivalent, key selection criteria include its 20 V VCEO, 2 A continuous IC, 0.6 V VCE(sat) at 2 A/200 mA drive, DFN2020-3 thermal performance, and suitability for battery-powered load switching and regulator pass elements.
Technical Context
This NPN bipolar junction transistor operates as a medium-power amplifying and switching device with fixed-emitter configuration. Its design emphasizes high DC current gain consistency across 500 mA–2 A loads and robust thermal behavior on FR4 PCBs-especially with collector pad area optimization.
The device uses silicon planar epitaxial technology with an exposed copper die pad for direct thermal path to the PCB. It exhibits fT = 40–170 MHz and Cc = 22 pF, supporting stable operation up to mid-frequency switching while maintaining low saturation voltage under high-current drive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch or series-pass regulator applications. |
| IC (continuous) | 2 A - Continuous collector current rating at Tamb ≤ 25 °C; enables use in 2 A load switches without forced cooling on standard FR4. |
| hFE | 160–375 - DC current gain at VCE = 1 V, IC = 500 mA; ensures reliable base drive margin for 100–200 mA gate drivers or amplifier stages. |
| VCE(sat) | 0.6 V max at IC = 2 A, IB = 200 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switching. |
| Ptot | 1.65 W - Total power dissipation on 4-layer FR4 with 1 cm² collector pad; determines thermal footprint requirements for sustained 2 A operation. |
| Rth(j-a) | 76 K/W - Junction-to-ambient thermal resistance under optimal 4-layer PCB mounting; critical for junction temperature estimation in thermal design. |
| fT | 40–170 MHz - Transition frequency at VCE = 5 V, IC = 50 mA; supports stable small-signal amplification and moderate-speed switching. |
Pinout & Package
BC68-25PA is housed in a 3-terminal, leadless DFN2020-3 package (SOT1061), measuring 2.0 × 2.0 × 0.65 mm, with an exposed copper thermal pad on the bottom side for soldering directly to PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≥200 mA base drive for full 2 A saturation; sensitive to ESD due to lack of integrated protection. |
| 2 | Emitter (E) | Reference node for collector current; connected to ground or low-side return path; forms common-emitter topology with defined VBE ≈ 1 V at 1 A. |
| 3 | Collector (C) | Main current-carrying output terminal; electrically and thermally tied to exposed pad; must be routed to large copper area for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Exposed thermal pad | Direct thermal interface to PCB copper; reduces Rth(j-a) by up to 60% vs. standard SOT packages, enabling higher IC in compact layouts. |
| High hFE binning (160–375) | Narrower gain spread than standard BC68 variants; simplifies base resistor selection and improves current matching in parallel configurations. |
| Low VCE(sat) (≤0.6 V) | Reduces conduction loss to <1.2 W at 2 A, lowering thermal stress in battery-powered devices and extending runtime in portable regulators. |
| DFN2020-3 footprint | 2.0 × 2.0 mm body with 0.5 mm pitch; compatible with automated reflow assembly and supports >3× higher power density than SOT23 equivalents. |
| 32 V VCBO rating | Provides 12 V headroom above 20 V VCEO, improving surge tolerance during inductive load switching and transient overvoltage events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC68-16PA | Lower hFE bin: 85–375 (min 85 vs. 160 for BC68-25PA); identical VCEO, IC, package, and thermal specs. | Suitable where base drive current is limited or gain variation is acceptable; less margin for marginal drive conditions. | Select when optimizing for cost and base drive availability is guaranteed; avoid in precision current mirror or low-IB designs. |
| BC817-40,215 | SOT23 package (3.0 × 1.4 × 1.1 mm); lower Ptot (0.5 W), lower IC (0.5 A), hFE = 250–630; no exposed thermal pad. | Limited to <500 mA loads; unsuitable for 2 A applications or thermally demanding environments. | Use only for signal-level switching or low-current bias networks; not a functional replacement for BC68-25PA's power capability. |
Compared with BC68-16PA, BC68-25PA offers higher guaranteed hFE for reduced base drive overhead; compared with BC817-40, it provides 4× higher current capacity and 3× better thermal performance in half the footprint area.

FAQ
What is the maximum allowable junction temperature for BC68-25PA?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet Limiting Values table. Operation above this threshold risks permanent degradation of hFE, increased leakage, and bond wire failure. Thermal design must ensure Tj remains ≤150 °C under worst-case ambient and power dissipation conditions, using the specified Rth(j-a) values for the chosen PCB layout.
Can BC68-25PA be used in avalanche mode?
No-BC68-25PA is not rated or characterized for avalanche operation. Its VCEO = 20 V and VCBO = 32 V are absolute maximum ratings, not repetitive avalanche energy specifications. Intentional operation beyond VCEO may cause irreversible breakdown and parametric shift; external clamping or snubbing is required for inductive load switching.
Is the exposed pad electrically connected to any internal node?
Yes-the exposed thermal pad on the underside of the SOT1061 package is internally connected to the collector terminal. It must be soldered to a PCB copper pour designated as the collector net and sized per thermal requirements; floating or grounding the pad will compromise both electrical function and thermal performance.
Does BC68-25PA have built-in ESD protection?
No-BC68-25PA has no integrated ESD protection diodes. The base-emitter junction has a VEBO rating of only 5 V, making it susceptible to damage from human-body-model (HBM) discharges >2 kV. Handling and PCB layout require standard ESD controls: grounded workstations, ionized air, and series base resistors or external TVS if exposed to user-accessible interfaces.
