Product details
Overview
BC846BPNH-QX from Nexperia is an AEC-Q101-qualified NPN/PNP general-purpose double transistor in SOT363 (TSSOP6) package, rated for 65 V VCEO, 100 mA IC, and 175 °C junction temperature. It delivers matched hFE (200–450), low VCE(sat) (200–300 mV at 100 mA), and <1.8 pF collector capacitance per transistor - enabling compact dual-polarity switching in automotive body control modules.
For engineers reviewing the BC846BPNH-QX datasheet, BC846BPNH-QX pinout, BC846BPNH-QX application, or BC846BPNH-QX equivalent, this device supports high-temperature dual-transistor functions including complementary signal inversion, push-pull driver stages, and redundant load switching where mutual interference must be avoided.
Technical Context
This dual discrete device integrates one NPN (TR1) and one PNP (TR2) transistor in a single SOT363 package with electrically isolated die. Each transistor operates independently with separate emitter, base, and collector terminals - no shared junctions or thermal coupling beyond package-level conduction.
It supports bidirectional current handling (±100 mA), features symmetric breakdown ratings (VCEO = ±65 V, VCBO = ±80 V), and maintains stable hFE across −40 °C to +175 °C ambient, verified per AEC-Q101 stress test conditions including HTGB, HTRB, and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | ±65 V - Enables use in 48 V automotive systems and industrial 24/36 V rails without derating. |
| IC | ±100 mA - Supports direct drive of small relays, LEDs, and logic-level interface loads. |
| hFE | 200–450 @ 2 mA - Ensures predictable DC gain for biasing and analog amplification stages. |
| VCE(sat) | 200–300 mV @ 100 mA - Minimizes conduction loss in high-efficiency switching applications. |
| Cc | 1.2 pF (NPN), 1.8 pF (PNP) - Reduces high-frequency signal distortion in RF-coupled or fast-switching circuits. |
| Tj(max) | 175 °C - Allows operation in under-hood environments without forced cooling. |
| Rth(j-a) | 375 K/W (per device) - Defines thermal budget for PCB layout on FR4 with standard copper footprint. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, 6-terminal configuration with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-impedance current sink node for NPN transistor; connects to ground or low-side load return. |
| 2 | Base of TR1 (NPN) | Control input for NPN switch/amplifier; requires ~0.7 V forward bias relative to E1. |
| 3 | Collector of TR2 (PNP) | Current source node for PNP transistor; connects to positive rail or high-side load supply. |
| 4 | Emitter of TR2 (PNP) | High-impedance current source terminal; ties to VCC or regulated supply for sourcing. |
| 5 | Base of TR2 (PNP) | Inverted control input for PNP; active low with ~−0.7 V bias relative to E2. |
| 6 | Collector of TR1 (NPN) | Current sink output for NPN; drives loads connected between C1 and VCC. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated die structure eliminates crosstalk between TR1 and TR2 - critical for noise-sensitive analog sensing paths. |
| Closely matched hFE | Both transistors share identical gain distribution (200–450), enabling precise complementary biasing in Class-B amplifier stages. |
| AEC-Q101 qualification | Validated for automotive use per HTGB, HTRB, and temperature cycling tests - supports ASIL-B system integration without additional qualification. |
| Low VCE(sat) | 200 mV max at 100 mA ensures <20 mW conduction loss per transistor - extends battery life in always-on vehicle modules. |
| High-temperature operation | Rated up to 175 °C junction temperature - eliminates need for heatsinking in engine bay or powertrain control units. |
Applications
| Automotive Door Module | Industrial Push-Pull Driver |
|---|---|
Use Scenario: Controlling window lift motor direction via H-bridge half-bridge outputs. IC Role / Device Role / Timing Role: Dual-transistor pair provides complementary high-side (PNP) and low-side (NPN) switching in discrete H-bridge leg. Use Value: Eliminates need for two separate SOT23 packages, reducing PCB area by 40% and improving thermal symmetry across bridge legs. |
Use Scenario: Driving 24 V solenoid valves in programmable logic controller (PLC) output cards. IC Role / Device Role / Timing Role: NPN switches valve ground path; PNP supplies regulated 24 V to auxiliary circuitry during fault isolation. Use Value: Independent saturation voltage specs (200–300 mV) ensure consistent valve activation timing across both polarities. |
| LED Tail Light Control | Redundant Power Switch |
Use Scenario: Dimmable brake/tail LED array with PWM-controlled current regulation. IC Role / Device Role / Timing Role: NPN handles PWM-switched cathode current; PNP enables reverse-polarity protection and standby biasing. Use Value: Matched hFE ensures identical current gain across dimming range, maintaining consistent LED brightness linearity. |
Use Scenario: Dual-redundant 12 V load switch in safety-critical ADAS camera power domain. IC Role / Device Role / Timing Role: One transistor serves primary switch; second provides fail-safe backup path with independent control. Use Value: Isolated die structure prevents single-point failure propagation - meets ISO 26262 hardware fault tolerance requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN/PNP dual-transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BSH-Q | NPN/NPN configuration only; lacks PNP element. | Not suitable for complementary switching or level-shifting requiring opposite polarity devices. | Select when dual low-side switching is required and no high-side sourcing is needed. |
| BC856BSH-Q | PNP/PNP configuration only; no NPN element. | Cannot implement standard open-collector or sink-driver topologies without external NPN. | Choose only for dual high-side sourcing applications such as dual pull-up networks. |
Compared with BC846BPNH-QX, BC846BSH-Q and BC856BSH-Q each provide only half the functional capability - neither supports true complementary switching in a single package, making them unsuitable drop-in replacements for applications requiring integrated NPN+PNP functionality.

FAQ
Is BC846BPNH-QX pin-compatible with BC847BPNH-Q?
No. BC846BPNH-QX uses SOT363 pinout (E1-B1-C2-E2-B2-C1), while BC847BPNH-Q has different gain binning and may differ in thermal resistance and saturation voltage tolerances. Pin numbering is identical, but electrical behavior under high-current or high-temperature conditions is not interchangeable without validation.
Can BC846BPNH-QX replace discrete BC846B and BC856B in existing designs?
Yes, provided PCB layout accommodates SOT363 footprint and routing respects isolated terminal assignments. The dual-device integration reduces component count and improves thermal tracking between NPN and PNP elements, but requires verification of trace inductance and grounding due to shared package substrate.
What is the maximum continuous power dissipation per transistor at 100 °C ambient?
At Tamb = 100 °C, Ptot derates linearly from 270 mW (per transistor) at 25 °C using Rth(j-a) = 556 K/W. This yields ~155 mW max per transistor - sufficient for 100 mA switching at VCE(sat) ≤ 300 mV, assuming adequate PCB copper area per Fig. 1.
Does BC846BPNH-QX support pulse operation above 100 mA?
Yes. ICM = 200 mA peak (single pulse, tp ≤ 1 ms) is specified. However, VCE(sat) rises to ~850 mV at IC = 10 mA / IB = 0.5 mA, so pulse drive must maintain IB/IC ≥ 20 to avoid excessive heating during transient loads.
