Product details
Overview
DMMT32N45CV-7 from Diodes Incorporated is a matched NPN bipolar transistor pair in a single SOT563 package, rated for 45V VCEO, 100mA IC, and featuring hFE matching ≤5% and VBE(on) matching ≤2mV at 2mA - designed for precision current mirroring and differential amplification in space-constrained automotive and industrial signal conditioning circuits.
For engineers reviewing the DMMT32N45CV-7 datasheet, DMMT32N45CV-7 pinout, DMMT32N45CV-7 application, or DMMT32N45CV-7 equivalent, key selection criteria include dual-transistor matching tolerance, thermal derating on 1oz FR-4 PCB, SOT563 footprint compatibility, and AEC-Q101 qualification readiness for automotive-grade analog front-ends.
Technical Context
This device integrates two electrically isolated NPN transistors on a single die within a thermally coupled SOT563 package, enabling tightly matched DC parameters (hFE, VBE) critical for high-accuracy current mirrors and emitter-coupled logic stages. Its 470°C/W RθJA reflects thermal performance under standard 1oz copper layout conditions.
The matched pair supports operation across –55°C to +150°C with 4000V HBM ESD rating and exhibits fT = 100–300MHz, supporting RF biasing and fast-switching applications up to ~100MHz where gain consistency between devices is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45V - Maximum collector-emitter voltage before breakdown; defines safe operating range in low-voltage switching and linear amplifier stages. |
| IC | 100mA continuous - Sets upper limit for load current handling per transistor in mirrored bias networks or active loads. |
| hFE Matching | ≤5% (hFE1/hFE2 ≥ 0.95) - Enables <0.1% current error in precision mirror configurations at 2mA bias. |
| VBE Matching | ≤2mV difference - Ensures sub-0.3% offset in differential pair inputs and improves common-mode rejection in op-amp input stages. |
| fT | 100–300MHz - Supports stable small-signal amplification and bias control in HF analog front-ends up to UHF band edges. |
| RθJA | 470°C/W - Specifies thermal resistance on minimal 1oz FR-4 pad; requires careful layout for >150mW power dissipation. |
| ESD HBM | 4000V - Confirms robustness against human-body discharge during board assembly and handling in production environments. |
Pinout & Package
Package: SOT563 - ultra-compact 6-pin surface-mount package with 0.5mm pitch, 1.6mm × 1.6mm footprint, and 0.6mm max height; optimized for high-density automotive PCBs and portable instrumentation.

| 2 (E1) | Emitter of Transistor 1 | Reference terminal for T1; often tied to ground or current-sense resistor in mirror topologies. |
| 3 (B1) | Base of Transistor 1 | Control input for T1; used for bias setting or feedback injection in matched-pair feedback loops. |
| 4 (B2) | Base of Transistor 2 | Independent control input for T2; enables differential base drive or independent bias adjustment. |
| 5 (E2) | Emitter of Transistor 2 | Reference terminal for T2; may be connected to shared emitter node or separate sensing path. |
| 6 (C2) | Collector of Transistor 2 | Output node for second transistor; forms complementary output in differential pairs or mirrored current source. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched NPN transistor pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTDM3205ZTA | Higher VCEO (60V), lower hFE matching (±10%), SOT-363 package (larger footprint, 2.1mm × 2.0mm) | Preferred for higher-voltage industrial PLC I/O modules where matching tolerance is secondary to breakdown margin | Select when >45V headroom is required and PCB area allows larger package; not drop-in due to pinout and size differences |
| MBT3904DW1T1G | Same SOT-363 package, no guaranteed hFE or VBE matching; typical hFE spread ±20% | Suitable for non-critical biasing in consumer audio amplifiers where cost dominates over precision | Choose only for cost-sensitive, non-automotive designs where matching is not required; lacks AEC-Q101 support |
Compared with ZXTDM3205ZTA and MBT3904DW1T1G, DMMT32N45CV-7 uniquely delivers ≤5% hFE matching and ≤2mV VBE matching in the smallest available footprint (SOT563), making it the only option for space-constrained automotive analog circuits requiring both precision and miniaturization.

FAQ
Is DMMT32N45CV-7 qualified to AEC-Q101?
No, DMMT32N45CV-7 is not formally AEC-Q101 qualified, but it is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Customers requiring full qualification must engage Diodes' automotive team for custom qualification testing and change control processes.
What is the maximum power dissipation per transistor at 85°C ambient?
At TA = 85°C, the derated power dissipation is 135mW per transistor, calculated using the 470°C/W RθJA and 150°C maximum junction temperature: PD = (150 − 85) / 470 ≈ 0.138W. This assumes standard 1oz FR-4 layout with minimum recommended pads.
Can DMMT32N45CV-7 be used in linear amplifier configurations?
Yes - its 45V VCEO, 100mA IC, and 100–300MHz fT support Class-A and Class-AB small-signal amplification up to ~50MHz. However, thermal derating must be applied above 25°C ambient, and VCE should remain below 30V for optimal linearity per SOA curves.
Does the SOT563 package support automated optical inspection (AOI)?
Yes - the SOT563's 0.5mm lead pitch, coplanar terminals, and matte tin finish are compatible with standard AOI systems used in automotive electronics manufacturing. The top-view marking "2V2" and date code provide unambiguous identification for traceability verification.
