Product details
Overview
BC856UE6327HTSA1 from Infineon Technologies is a dual PNP silicon small-signal transistor array in SOT-363 (SC74) 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 = 100 mA / IB = 5 mA, enabling use in AF input stages and driver circuits for automotive and industrial control modules.
For engineers reviewing the BC856UE6327HTSA1 datasheet, BC856UE6327HTSA1 pinout, BC856UE6327HTSA1 application, or BC856UE6327HTSA1 equivalent, key selection criteria include dual-PNP matching tolerance, AEC-Q101 qualification, low VCE(sat), thermal resistance RthJS ≤ 130 K/W, and RoHS-compliant SOT-363 packaging for space-constrained PCB layouts.
Technical Context
This dual-transistor array integrates two independent PNP BJTs on a single die with tight parameter matching-critical for differential pair amplifiers and complementary driver stages. Its design supports DC-coupled AF signal conditioning and current-source biasing where thermal tracking between devices reduces drift.
The device operates across −65 °C to +150 °C junction temperature range, with specified fT = 250 MHz at IC = 20 mA and Ccb = 1.5 pF, confirming suitability for high-frequency analog switching up to mid-VHF band without parasitic resonance issues.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Supports rail-to-rail operation in 48 V automotive subsystems and 24 V industrial logic interfaces. |
| hFE | 200–630 - Enables stable current gain across wide collector current range (10 µA–100 mA), reducing base drive complexity. |
| VCE(sat) | ≤250 mV @ IC=100 mA - Minimizes conduction loss in active-low switch applications and improves power efficiency. |
| RthJS | ≤130 K/W - Allows sustained 250 mW dissipation at board-level soldering point temperatures ≤118 °C. |
| fT | 250 MHz - Supports audio-frequency amplification with margin for transient response in feedback-controlled drivers. |
| Ccb | 1.5 pF - Limits Miller effect in common-emitter configurations, preserving bandwidth in multi-stage amplifiers. |

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 |
|---|---|---|---|
| BC856B,215 (Nexperia) | Single PNP transistor in SOT-23; no dual configuration or internal isolation. | Requires two discrete devices and additional layout area; lacks inter-device matching. | Select only when dual-channel integration is unnecessary and board space permits discrete placement. |
| MBT3906DW1T1G (ON Semiconductor) | Same SOT-363 package but hFE min = 100 (vs. 200), VCEO = 40 V (vs. 65 V), and no AEC-Q101 qualification. | Limited to non-automotive 24 V systems; higher VCE(sat) (300 mV) increases conduction loss. | Acceptable for cost-sensitive industrial controls where 65 V rating and automotive qualification are not required. |
Compared with BC856B,215 and MBT3906DW1T1G, BC856UE6327HTSA1 uniquely combines dual-channel integration, AEC-Q101 compliance, 65 V breakdown, and tight hFE matching-making it optimal for space-constrained, high-reliability automotive and industrial driver applications.

FAQ
What is the maximum continuous collector current per transistor in BC856UE6327HTSA1?
The maximum continuous collector current per transistor is 100 mA at TS ≤ 118 °C. This rating assumes proper PCB copper pour and thermal vias to maintain junction temperature below 150 °C. Pulse operation up to 200 mA is allowed for tp ≤ 10 ms with duty cycle ≤ 2%.
Does BC856UE6327HTSA1 support direct connection to 3.3 V microcontroller GPIOs?
Yes-its VBE(sat) ≤ 850 mV at IC = 100 mA ensures full turn-on with standard 3.3 V logic outputs. Base resistor calculation must account for hFE minimum of 200 to guarantee saturation; typical design uses 10 kΩ for 3.3 V drive with IC = 10 mA.
How is pin 1 identified on the SOT-363 package of BC856UE6327HTSA1?
Pin 1 is marked by a laser-etched dot or beveled edge located at the top-left corner of the package when the marking side faces up and the leads point downward. The physical outline matches JEDEC MO-178AA, with pin 1 adjacent to the chamfered corner of the 2.9 mm × 1.9 mm body.
Is BC856UE6327HTSA1 suitable for high-frequency switching above 10 MHz?
Yes-its fT = 250 MHz and Ccb = 1.5 pF support reliable switching up to ~50 MHz in common-emitter configurations. For >100 MHz operation, layout parasitics dominate; keep trace lengths <5 mm and use ground plane shielding to preserve bandwidth and minimize oscillation risk.
