Product details
Overview
PUMD2/DG/B4F from Nexperia is an NPN/PNP dual resistor-equipped transistor (RET) in a SOT363 (SC-88) surface-mount package, integrating two complementary bias-resistor transistors - one NPN and one PNP - each with 22 kΩ input and feedback resistors. It delivers 100 mA output current per transistor, supports ±50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal-level switching applications such as LED driver control and logic-level translation.
For engineers reviewing the PUMD2/DG/B4F datasheet, PUMD2/DG/B4F pinout, PUMD2/DG/B4F application, or PUMD2/DG/B4F equivalent, this page provides verified pin functions, thermal derating curves, built-in resistor ratios, saturation voltage at 10 mA/0.5 mA drive, and validated alternatives for digital interface consolidation in space-constrained PCBs.
Technical Context
The PUMD2/DG/B4F integrates two monolithic transistors - TR1 (NPN) and TR2 (PNP) - with matched on-chip bias networks (R1 = R2 = 22 kΩ, ratio 0.8–1.2), enabling direct logic-level drive without external base resistors. Its dual-complementary topology allows push-pull output staging and bidirectional level shifting in compact digital I/O buffers.
Each transistor exhibits hFE ≥ 60 at 5 mA collector current, fT of 230 MHz (NPN) and 180 MHz (PNP), and VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA - confirming suitability for high-speed, low-power switching in automotive body electronics and industrial microcontroller peripheral interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports rail-to-rail operation in 24 V automotive systems with margin against load dump transients. |
| IO | 100 mA - Enables direct driving of small-signal loads like optocoupler LEDs or logic gate inputs without external amplification. |
| R1 / R2 | 22 kΩ ±25% - Eliminates need for two external base resistors per transistor, reducing BOM count and layout area by ~4 components per channel. |
| VCE(sat) | ≤150 mV @ IC=10 mA - Minimizes power loss (<1.5 mW per switch) and self-heating in always-on control nodes. |
| fT | 230 MHz (NPN), 180 MHz (PNP) - Allows clean switching up to ~10–20 MHz square waves in timing-critical digital isolation paths. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and cabin applications including door modules and HVAC controllers. |
| Ptot (per device) | 300 mW @ Tamb ≤25 °C - Enables operation in thermally constrained spaces when mounted on standard FR4 PCBs. |
Pinout & Package
SOT363 (SC-88) ultra-small 6-pin plastic package with 0.65 mm pitch, 2.2 mm × 1.35 mm footprint, and exposed pad for thermal relief. Designed for reflow soldering with defined land pattern (sot363_fr) per Nexperia's 2013 datasheet Rev. 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Common emitter reference for NPN transistor; connects to system ground or low-side return path. |
| 2 | input (base) TR1 | Logic-level input node for NPN transistor; internally biased via 22 kΩ resistor to VCC. |
| 3 | output (collector) TR2 | Active-low output terminal of PNP transistor; sinks current when TR2 is on. |
| 4 | GND (emitter) TR2 | Common emitter reference for PNP transistor; ties to VCC rail in high-side switch configurations. |
| 5 | input (base) TR2 | Logic-level input node for PNP transistor; internally biased via 22 kΩ resistor to GND. |
| 6 | output (collector) TR1 | Active-high output terminal of NPN transistor; sources current when TR1 is on. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN/PNP RET topology | Enables single-package push-pull output stages without discrete biasing, reducing board area by >30% vs. discrete transistor + resistor solutions. |
| Matched R1/R2 ratio (0.8–1.2) | Ensures consistent turn-on thresholds between NPN and PNP sections, critical for symmetrical switching in bus drivers and level translators. |
| VI(on)/VI(off) = 1.7–2.5 V / 0.8–1.1 V | Provides TTL/CMOS-compatible input thresholds, allowing direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting circuitry. |
| 150 °C max junction temperature | Supports operation in engine bay environments where ambient temperatures reach 125 °C, with 25 °C thermal margin. |
| Low Cc (2.5–3 pF) | Minimizes capacitive loading on driving signals, preserving edge integrity in >10 MHz digital control lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2T100MZ | Same SOT363 package; R1 = R2 = 10 kΩ; lower VCEO = 40 V; higher IO = 150 mA | Better suited for 3.3 V logic domains with tighter voltage margins; less robust in 24 V automotive systems | Select when driving low-voltage peripherals with higher current demand and no 50 V transient exposure. |
| PUMH2,115 | SOT363; NPN/NPN configuration only; R1 = 47 kΩ, R2 = open; no PNP section | Lacks complementary output capability; requires external PNP for push-pull; limited to unidirectional logic buffering | Choose only for NPN-only applications where dual-NPN pairing simplifies design, e.g., parallel GPIO expansion. |
Compared with NSVD2T100MZ and PUMH2,115, the PUMD2/DG/B4F uniquely offers matched NPN/PNP topology with 50 V rating and 22 kΩ biasing - making it the only option among the three qualified for AEC-Q101-compliant bidirectional switching in 12/24 V automotive subsystems.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The PUMD2/DG/B4F supports continuous operation from −55 °C to +150 °C ambient, with thermal derating beginning above 25 °C. At 100 °C ambient, its per-device power dissipation must be reduced to ≤150 mW (50% of rated 300 mW) per Figure 1 in the 2013 datasheet Rev. 8.
Can PUMD2/DG/B4F replace discrete transistors in existing designs without layout changes?
Yes - the SOT363 footprint matches industry-standard SC-88 land patterns. Pin compatibility with legacy PUMH1 and PUMB1 devices enables drop-in replacement, provided the original design used identical 22 kΩ biasing and did not require higher VCEO than 50 V.
Does PUMD2/DG/B4F support PWM-driven LED dimming?
Yes - its 230 MHz fT (NPN) and 180 MHz fT (PNP), combined with <150 mV VCE(sat), enable clean switching at PWM frequencies up to 20 MHz. Verified performance at 10 kHz–100 kHz makes it ideal for camera flash and status LED dimming with minimal thermal rise.
Is the internal resistor ratio stable over temperature and voltage?
Yes - the R2/R1 ratio remains within 0.8–1.2 across −55 °C to +150 °C and 0–40 V input range, as confirmed in Table 2 and Figure 13–14 of the datasheet. This ensures consistent switching thresholds and prevents shoot-through in push-pull configurations.
