Product details
Overview
NID5100GW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified automotive ideal diode IC that replaces Schottky diodes in low-voltage power OR-ing and reverse-polarity-protected supply paths. It operates from 1.2 V to 5.5 V, delivers up to 1.5 A forward current, regulates forward voltage drop to 31 mV (typ) at 10 mA, and integrates reverse-polarity protection (RPP) and active-low enable (EN) with open-drain status (ST) output - used in automotive cluster displays and ADAS domain controllers.
For engineers reviewing the NID5100GW-Q100 datasheet, NID5100GW-Q100 pinout, NID5100GW-Q100 application, or NID5100GW-Q100 equivalent, this device serves as a low-quiescent-current (240 nA typ), input-polarity-protected ideal diode for automotive power rail management where <50 mV forward regulation, -6 V absolute max reverse input, and seamless dual-supply OR-ing are required.
Technical Context
The NID5100GW-Q100 implements a gate-regulated PMOS architecture with dual-mode operation: forward conduction under EN low (regulated VREG ≈ 31 mV) and automatic reverse-current blocking (RCB) triggered at VOUT − VIN ≥ 30.5 mV (typ). Its RPP circuitry remains active regardless of EN state, enabling autonomous protection against −6 V input reversal.
It supports hybrid OR-ing topologies - including NID5100 + external PMOS, dual-NID5100, or NID5100 + Schottky - and uses an open-drain ST pin to signal conduction (high-Z) or blocking/disabled (low) states, allowing real-time monitoring or control of auxiliary power switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 1.2 V to 5.5 V - enables use across automotive 1.8 V, 3.3 V, and 5 V rails without level-shifting. |
| Forward Regulation Voltage (VREG) | 31 mV (typ) at IOUT = 10 mA, VIN = 3.3 V - reduces power loss by ~90% vs. typical Schottky diodes (~300 mV). |
| Max Continuous Current | 1.5 A - supports high-reliability power path switching in body control modules and display subsystems. |
| Quiescent Current (IIN(Q)) | 240 nA (typ) at 3.3 V - minimizes standby power draw in always-on automotive domains. |
| Reverse Polarity Protection | −6 V absolute max on IN - prevents damage during battery misconnection or supply polarity reversal. |
| Enable Logic | Active-low EN with 0.4 V max VIL - compatible with standard CMOS logic and microcontroller GPIOs. |
| Status Pin Output | Open-drain ST: high-Z when regulating, low when disabled or reverse-biased - enables direct MCU interrupt or PMOS gate control. |
Pinout & Package
The NID5100GW-Q100 is housed in a TSSOP6 (SOT363-2) package measuring 2.1 mm × 1.25 mm × 0.95 mm - footprint-compatible with SC-88/SC70-6 standards and optimized for space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Anode-equivalent input | Primary power input node; connects to upstream supply (e.g., battery or DC-DC output); withstands −6 V reverse polarity. |
| GND (Pin 2) | Power ground reference | System ground return for internal regulation amplifier and logic; must be low-impedance for stable VREG control. |
| EN (Pin 3) | Active-low enable control | Drives device into regulated conduction (EN ≤ 0.4 V) or disables it (EN ≥ 1.2 V); must not float - tie to GND or MCU GPIO. |
| n.c. (Pin 4) | No internal connection | Unused terminal; may be left floating or tied to GND for mechanical stability - no electrical function. |
| ST (Pin 5) | Open-drain status output | Signals regulation (high-Z) or blocking/disabled (low); requires external pull-up to monitor or drive external PMOS in OR-ing circuits. |
| OUT (Pin 6) | Cathode-equivalent output | Regulated power output to load; maintains VOUT = VIN − VREG during forward conduction; blocks reverse current autonomously. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for −40 °C to +125 °C ambient operation - certified for engine bay and infotainment module deployment. |
| Integrated Reverse-Polarity Protection (RPP) | Blocks −6 V input without external components - eliminates need for discrete reverse-battery protection FETs or diodes. |
| Low-loss forward regulation | VREG = 31 mV (typ) at light load - cuts conduction loss vs. Schottky by >90%, critical for thermally constrained clusters. |
| Autonomous reverse-current blocking (RCB) | Triggers at VOUT − VIN ≥ 30.5 mV (typ) - prevents backfeed from downstream rails even when EN is high or floating. |
| Ultra-low quiescent current | IIN(Q) = 240 nA (typ) at 3.3 V - extends battery life in always-on ADAS sensors and telematics modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ideal diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26631QPWPRQ1 | Higher 2.7 V min VIN, 2.5 A rating, integrated overvoltage clamp - no RPP; requires external reverse-battery FET. | Better suited for 12 V automotive systems with overvoltage transients; lacks monolithic RPP for low-voltage battery inputs. | Select when system-level overvoltage protection is prioritized over input polarity robustness below 2.7 V. |
| LM74700QDBVRQ1 | Lower 1.5 V min VIN, 3.5 A rating, no integrated RPP - relies on external circuit for reverse polarity handling. | Optimized for high-current 3.3 V/5 V OR-ing but adds design complexity for RPP; higher IQ (1.2 µA) than NID5100GW-Q100. | Choose for >2 A loads where ultra-low VREG (20 mV typ) justifies added external protection components. |
Compared with TPS26631QPWPRQ1 and LM74700QDBVRQ1, the NID5100GW-Q100 uniquely integrates RPP, operates down to 1.2 V, and achieves sub-µA quiescent current - making it optimal for low-voltage, space-constrained automotive modules requiring autonomous polarity and reverse-current protection.

FAQ
What is the maximum reverse voltage the NID5100GW-Q100 can withstand on its IN pin?
The NID5100GW-Q100 supports −6 V absolute maximum reverse voltage on the IN pin per its limiting values table. This rating applies regardless of EN state and enables robust protection against battery misconnection in automotive environments - no external components needed to achieve this level of reverse-polarity immunity.
How does the ST pin behave during reverse-current blocking?
During reverse-current blocking - whether due to VOUT > VIN or EN = high - the ST pin is actively pulled low (≤0.1 V at 1 mA sink). This provides unambiguous hardware signaling to a microcontroller or external PMOS gate driver, enabling immediate system-level response such as disabling secondary supplies or logging fault conditions.
Can the NID5100GW-Q100 operate with a 1.2 V input supply?
Yes - the NID5100GW-Q100 is fully specified from 1.2 V to 5.5 V input. At 1.2 V, it maintains functional VREG regulation (up to ~50 mV at 10 mA) and retains all protections including RPP and RCB, making it uniquely suitable for emerging 1.2 V automotive domains like next-gen ADAS sensor hubs and low-power MCUs.
Is an external capacitor required on the OUT pin?
Yes - the datasheet mandates a minimum 0.1 µF output capacitor (COUT) on the OUT pin for stable regulation and transient response. Recommended values range from 0.1 µF to 100 µF depending on load dynamics; 0.47 µF is typical for automotive cluster applications to suppress ripple while minimizing board area.
