Product details
Overview
PUMH19 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (TSSOP6) package, featuring built-in 22 kΩ input bias resistors (R1), 50 V VCEO, 100 mA output current per transistor, and AEC-Q101 qualification-designed for low-current digital logic interfacing and IC input control in automotive body electronics.
For engineers reviewing the PUMH19 datasheet, PUMH19 pinout, PUMH19 application, or PUMH19 equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, thermal derating curves, and direct replacement guidance for discrete BJT + resistor networks in space-constrained PCB layouts.
Technical Context
The PUMH19 integrates two independent NPN transistors, each with a dedicated 22 kΩ base-input resistor (R1) and open-circuit R2, enabling direct TTL/CMOS-level drive without external bias components. It operates with VCEO = 50 V, IO = 100 mA per channel, and supports ambient temperatures from −65 °C to +150 °C.
Its thermal resistance is 416 K/W per device on FR4 PCB (single-sided copper), and it exhibits hFE ≥ 100 at IC = 1 mA, VCE = 5 V, with VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA-optimized for fast-switching, low-power digital signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 22 kΩ (15.4–28.6 kΩ range) - Integrated base bias resistor eliminates external component; reduces BOM count by 2× per channel. |
| Ptot (per device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C on FR4 PCB; defines thermal headroom for dual-channel operation. |
| hFE | ≥100 - DC current gain at IC = 1 mA; ensures reliable saturation with standard logic-level base drive. |
| VCE(sat) | ≤150 mV - Low saturation voltage at IC/IB = 20; minimizes power loss and self-heating in switching applications. |
Pinout & Package
Package: SOT363 (TSSOP6), 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, surface-mount plastic package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1; internally connected to 22 kΩ resistor R1; accepts CMOS/TTL logic signals directly. |
| 3 | O2 | Collector output for TR2; active-high switching node for second channel load. |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor channel. |
| 5 | I2 | Base input for TR2; internally connected to 22 kΩ resistor R1; electrically isolated from I1. |
| 6 | O1 | Collector output for TR1; active-high switching node for first channel load. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive under stress test standard; supports under-hood and body-control module deployment. |
| Dual NPN RET architecture | Two independent channels with matched R1 = 22 kΩ bias resistors; eliminates 4 external resistors in typical driver circuits. |
| SOT363 footprint | 0.65 mm pitch, 2.1 mm × 1.25 mm area; enables high-density routing in compact ECUs and sensor nodes. |
| Low VCE(sat) | ≤150 mV at IC = 10 mA; reduces conduction loss and improves efficiency in battery-powered logic interface stages. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|

Use Value: Maintains <100 nA leakage across temperature range, preventing unintended activation of sensitive analog circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD19 | Complementary NPN/PNP pair; identical R1 = 22 kΩ, same SOT363 package, but mixed polarity. | Required where one channel needs high-side (PNP) switching alongside low-side (NPN) control. | Select when designing push-pull or level-shifted output stages requiring bidirectional drive capability. |
| PUMB19 | PNP/PNP configuration; same VCEO = 50 V, IO = 100 mA, R1 = 22 kΩ, but inverted polarity per channel. | Used in high-side switching topologies (e.g., PMOS gate drivers or positive rail loads). | Choose for applications needing active-low control of positive-rail peripherals without external inverters. |
Compared with PUMD19 and PUMB19, the PUMH19 uniquely provides dual NPN topology-making it optimal for grounded-load configurations where both channels require low-side switching, while its AEC-Q101 rating and thermal performance ensure robustness in automotive and industrial environments.

FAQ
What is the function of R2 in the PUMH19?
R2 is open (unconnected) in the PUMH19-confirmed in Table 8 and Section 1 of the datasheet. This configuration provides single-resistor biasing (R1 only) per transistor, simplifying drive requirements and supporting direct logic-level input without feedback or pull-down networks.
Can PUMH19 be used in linear amplification mode?
No-the PUMH19 is characterized and qualified exclusively for switching applications. Its hFE specification is given only at IC = 1 mA, and no linearity, frequency response, or small-signal parameters are provided in the datasheet. It lacks design validation for analog amplification.
Is thermal derating required above 25 °C ambient?
Yes-per Figure 1, total device power dissipation must be linearly derated above 25 °C at 4.8 mW/°C (300 mW ÷ 62.5 °C), reaching 0 mW at 87.5 °C. This applies to continuous operation on standard FR4 PCB with single-sided copper.
How does the marking code 'H6%' map to PUMH19?
The marking code 'H6%' appears on the top surface of the SOT363 package, where 'H6' identifies the PUMH19 type and '%' is a placeholder for the manufacturing site code (e.g., H6A, H6B). This matches Table 4 and is verified in the physical package outline (Figure 6).
