Product details
Overview
BC856SE6327BTSA1 from Infineon Technologies is a dual PNP silicon small-signal transistor array in SOT-363 (SC-74) package, configured as two galvanically isolated transistors with matched characteristics. It delivers VCEO = 65 V, hFE = 200–630 at IC = 2 mA, and VCE(sat) ≤ 250 mV at IC = 10 mA / IB = 0.5 mA. Used in AF input stages and driver circuits for automotive audio amplifiers and industrial sensor signal conditioning.
For engineers reviewing the BC856SE6327BTSA1 datasheet, BC856SE6327BTSA1 pinout, BC856SE6327BTSA1 application, or BC856SE6327BTSA1 equivalent, key selection criteria include dual-transistor matching tolerance, low VCE(sat) under 10 mA drive, AEC-Q101 qualification, and thermal resistance RthJS ≤ 140 K/W for compact board-level thermal design.
Technical Context
This dual PNP array integrates two discrete transistors with tightly controlled parameter matching-especially hFE and VBE(sat)-enabling balanced differential pair operation without external trimming. Its galvanic isolation between TR1 and TR2 supports independent biasing and prevents crosstalk in feedback or current mirror configurations.
The device operates across –65 °C to +150 °C junction temperature, with guaranteed performance up to TS = 115 °C. Thermal derating follows a defined Ptot vs. TS curve (250 mW at 115 °C), and pulse handling supports duty cycles ≤ 2% with tp < 300 µs per JEDEC JESD22-A114.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Supports rail-to-rail operation in 48 V automotive supply domains with margin. |
| hFE (IC = 2 mA) | 200–630 - Enables stable current gain across production lots for precision current mirrors. |
| VCE(sat) (IC = 10 mA) | ≤ 250 mV - Minimizes conduction loss in low-voltage switching nodes like level shifters. |
| fT | 250 MHz - Sufficient for AF and low-MHz signal amplification without phase degradation. |
| RthJS | ≤ 140 K/W - Allows direct PCB copper pour thermal coupling without heatsink in space-constrained modules. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL and TC. |
Pinout & Package
SOT-363 (SC-74) surface-mount package with 6-pin lead frame, 0.65 mm pitch, and exposed thermal pad (not electrically connected). Dimensions: 2.1 × 2.0 × 1.1 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of Transistor 1 | Low-impedance current sink node for TR1; tied to local ground reference in common-emitter stage. |
| 2 (B1) | Base of Transistor 1 | High-impedance control input; requires current-limited bias network to avoid saturation overshoot. |
| 3 (C2) | Collector of Transistor 2 | Active load or output node for TR2; routed to VCC via pull-up resistor in switch mode. |
| 4 (E2) | Emitter of Transistor 2 | Independent emitter terminal enabling separate biasing or current sensing for TR2. |
| 5 (B2) | Base of Transistor 2 | Isolated control path for TR2; enables differential pair or complementary push-pull configuration. |
| 6 (C1) | Collector of Transistor 1 | Main output collector for TR1; designed for direct connection to load or next-stage base. |
Key Features
| Feature | Design Value |
|---|---|
| Galvanic isolation between TR1 and TR2 | Prevents signal coupling and enables independent bias networks for matched differential operation. |
| Matched hFE and VBE(sat) | Reduces offset voltage drift in current mirrors and improves linearity in analog gain blocks. |
| Low VCE(sat) at 10 mA | Enables efficient operation in 3.3 V/5 V logic-level interface circuits without additional level-shifting. |
| Pb-free & RoHS-compliant | Meets EU Directive 2011/65/EU and supports lead-free reflow profiles (JEDEC J-STD-020, peak 260 °C). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857SE6327HTSA1 | VCEO = 45 V (vs. 65 V); otherwise identical pinout, matching, and thermal specs. | Not suitable for 48 V rail systems; limited to 24 V or lower automotive sub-systems. | Select only when VCC ≤ 30 V and higher hFE typ. (330) is prioritized over breakdown margin. |
| MBT3906DW1T1G | Same SOT-363 package but non-AEC-Q101; hFE min. = 100 (vs. 200); RthJS = 160 K/W. | Lacks automotive qualification; higher thermal resistance limits continuous power in sealed enclosures. | Acceptable for cost-sensitive industrial controls where AEC-Q101 is not mandated and thermal margin ≥ 15 °C exists. |
Compared with BC856SE6327BTSA1, BC857SE6327HTSA1 trades breakdown voltage for slightly higher gain, while MBT3906DW1T1G reduces qualification assurance and thermal performance to meet budget constraints-neither offers drop-in replacement without system-level validation.

FAQ
What is the maximum continuous collector current per transistor?
The absolute maximum DC collector current per transistor is 100 mA, as specified in the "Maximum Ratings" table. Derating applies above TS = 115 °C, and pulsed operation up to 200 mA is allowed for tp ≤ 10 ms with duty cycle ≤ 2%, per JEDEC JESD22-A114.
Is BC856SE6327BTSA1 pin-compatible with BC857S variants?
Yes-both BC856S and BC857S share identical SOT-363 pinout (E1-B1-C2-E2-B2-C1), same package outline, and mechanical footprint. However, BC857S has lower VCEO (45 V) and VCBO (50 V), so electrical substitution requires verification of voltage margin in the target circuit.
Does this device require external bias resistors for basic switching operation?
Yes-BC856SE6327BTSA1 is a bare transistor array with no integrated biasing. For switching use, external base resistors must be selected to ensure IB ≥ IC/hFE(min), accounting for worst-case hFE = 200 at IC = 2 mA and elevated temperature.
How is thermal performance affected by PCB layout?
Thermal resistance RthJS ≤ 140 K/W assumes minimum 10 mm² copper pour connected to pins 1, 4, and the thermal pad (if present). Reducing copper area below 5 mm² increases RthJS by ≥ 35 K/W, risking junction temperature exceedance above 115 °C at full 250 mW dissipation.
