Product details
Overview
PMP4501QAS from Nexperia is an AEC-Q101-qualified NPN/NPN matched double transistor in a DFN1010B-6 (SOT1216) package, designed for precision analog functions requiring tight parameter matching. It delivers 45 V VCEO, 100 mA IC, and guaranteed hFE matching (0.95–1.05) and VBE matching (≤2 mV) at 2 mA/5 V, enabling high-accuracy current mirroring in automotive sensor signal conditioning circuits.
For engineers reviewing the PMP4501QAS datasheet, PMP4501QAS pinout, PMP4501QAS application, or PMP4501QAS equivalent, key selection criteria include dual-transistor matching tolerance, ultra-thin 0.37 mm profile for space-constrained PCBs, AEC-Q101 qualification for under-hood use, and thermal resistance of 358 K/W (per device) on FR4.
Technical Context
This matched pair integrates two identical NPN transistors on a single die within a thermally enhanced leadless DFN package, ensuring correlated thermal drift and minimized inter-transistor parameter variation. Its pinout (B1, B2, C2, E2, E1, C1) supports direct differential configuration without external routing asymmetry.
The device operates with VCEO = 45 V and IC = 100 mA per transistor, while maintaining low VCE(sat) ≤ 400 mV at 100 mA/5 mA drive and fT ≥ 100 MHz - enabling stable operation in both DC biasing and moderate-frequency analog feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in current mirror or amplifier stages. |
| IC | 100 mA - Continuous collector current per transistor; sets usable dynamic range for biasing and small-signal amplification. |
| hFE1/hFE2 | 0.95–1.05 - Ratio of DC current gains between transistors; ensures ≤5% gain mismatch for balanced differential operation. |
| VBE1−VBE2 | ≤2 mV - Absolute difference in base-emitter voltage at 2 mA/5 V; enables sub-0.1% current ratio accuracy in mirrors. |
| Rth(j-a) (per device) | 358 K/W - Junction-to-ambient thermal resistance on FR4 PCB; determines maximum power dissipation before Tj exceeds 150 °C. |
| Ptot (per device) | 350 mW - Total power dissipation limit at Tamb ≤ 25 °C; constrains combined static + dynamic losses in dual-transistor layout. |
| fT | ≥100 MHz - Transition frequency at 10 mA/5 V; supports stable closed-loop behavior up to ~10 MHz in emitter-coupled configurations. |
Pinout & Package
DFN1010B-6 (SOT1216) is a 0.37 mm height, 1.05 × 1.05 mm leadless plastic package with exposed thermal pad, optimized for automated placement and high-density automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B1 | Base of transistor TR1 - referenced to E1 for independent bias control of first transistor. |
| 2 | B2 | Base of transistor TR2 - referenced to E2 for independent bias control of second transistor. |
| 3 | C2 | Collector of TR2 - output node for TR2; electrically isolated from C1 to prevent cross-coupling in differential pairs. |
| 4 | E2 | Emitter of TR2 - common reference for TR2; paired with B2/C2 to form complete second transistor unit. |
| 5 | E1 | Emitter of TR1 - common reference for TR1; paired with B1/C1 to form complete first transistor unit. |
| 6 | C1 | Collector of TR1 - output node for TR1; physically adjacent to C2 but electrically separate to preserve matching integrity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control modules and body electronics. |
| Current gain matching (hFE1/hFE2) | 0.95–1.05 tolerance ensures predictable current division in mirrored bias networks. |
| Base-emitter voltage matching (VBE1−VBE2) | ≤2 mV at 2 mA enables <0.1% error in precision current sources without trimming. |
| Ultra-low profile (0.37 mm) | Reduces board stack height in multi-layer ADAS sensor modules and compact ECUs. |
| Application-optimized pinout | Adjacent emitter-collector pairs (E1/C1, E2/C2) minimize parasitic inductance in high-speed differential paths. |
Applications
| Current Mirror | Differential Amplifier |
|---|---|
|
Use Scenario: Precision bias current generation for op-amp input stages in automotive temperature sensors. IC Role / Device Role / Timing Role: Dual-transistor current mirror providing matched reference current to front-end amplifiers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | SO-8 package; hFE matching ±10%, no VBE matching spec; non-AEC-Q101. | Limited to industrial/commercial PCBs; unsuitable for automotive under-hood deployment. | Select only if AEC-Q101 compliance and sub-2 mV VBE matching are not required. |
| MBT3904DW1T2G | Same SOT-363 package; hFE matching ±15%; VBE matching not specified; AEC-Q101 qualified. | Acceptable for less demanding automotive functions like LED driver biasing, but insufficient for precision mirrors. | Choose when cost sensitivity outweighs matching performance, and thermal profile allows larger package. |
Compared with BC847BDW1T1G and MBT3904DW1T2G, PMP4501QAS provides tighter VBE matching (≤2 mV vs. unspecified), superior hFE tolerance (±5% vs. ±10–15%), and lower thermal resistance (358 K/W vs. ≥450 K/W), making it uniquely suitable for high-accuracy automotive analog signal chains.

FAQ
Is PMP4501QAS suitable for reflow soldering on standard FR4 PCBs?
Yes - the DFN1010B-6 package is qualified for lead-free reflow per J-STD-020. Recommended footprint matches Nexperia's sot1216_fr land pattern (1.1 mm × 0.6 mm pads, 0.35 mm spacing), and thermal performance data assumes standard FR4 with single-sided 1 oz copper.
What is the maximum junction temperature and how does it affect continuous operation?
The absolute maximum junction temperature is 150 °C. At ambient temperatures above 25 °C, power derating applies: total device dissipation must be reduced linearly beyond 350 mW using the 358 K/W Rth(j-a) value, reaching zero allowable power at Tamb ≈ 125 °C on standard FR4.
Does the matching specification apply across the full automotive temperature range?
No - hFE and VBE matching values (0.95–1.05 and ≤2 mV) are specified at Tamb = 25 °C. However, the monolithic die construction ensures correlated thermal drift, and application data shows <0.2% current ratio degradation from −40 °C to 125 °C in properly biased mirror configurations.
Can PMP4501QAS replace discrete single-transistor solutions in existing designs?
Yes - its pinout supports direct substitution in dual-transistor layouts, but requires verification of PCB pad geometry (DFN1010B-6 vs. older SOT-363/SOT-353 footprints) and thermal relief design, as the 0.37 mm height and thermal pad demand updated stencil and reflow profiles.
