Product details
Overview
BAT46GWX from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD123 surface-mount package. It delivers 100 V reverse voltage rating, 250 mA forward current capability, ≤850 mV forward voltage at 250 mA, ≤4 µA reverse leakage at 75 V, and 5.9 ns reverse recovery time - enabling high-speed switching and reverse polarity protection in compact power rails.
For engineers reviewing the BAT46GWX datasheet, BAT46GWX pinout, BAT46GWX application, or BAT46GWX equivalent, key selection criteria include its low VF/IR trade-off, SOD123 thermal performance (Rth(j-a) = 320 K/W on FR4), and verified clamping behavior under transient overvoltage conditions.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reverse voltage stability. Its low junction capacitance (39 pF at VR = 0 V) and fast trr (5.9 ns) stem from minimized minority carrier storage - critical for line termination and high-frequency clamping.
The device operates across –55 °C to 150 °C ambient, with thermal resistance optimized for standard SOD123 PCB footprints: Rth(j-sp) = 35 K/W at cathode solder point and Rth(j-a) = 190 K/W with 1 cm² cathode pad - supporting reliable power dissipation up to 660 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports input rail clamping in 48 V industrial systems without breakdown. |
| Forward Current (IF) | 250 mA continuous - suitable for low-power signal path protection and biasing circuits. |
| Forward Voltage (VF) | 710–850 mV @ 250 mA - reduces conduction loss and self-heating in compact layouts. |
| Reverse Leakage (IR) | 1–4 µA @ 75 V - ensures minimal standby current in battery-backed or energy-sensitive designs. |
| Reverse Recovery (trr) | 5.9 ns - enables clean switching in >10 MHz digital interfaces and ESD-coupled signal lines. |
| Junction Capacitance (Cd) | 39 pF @ 0 V - preserves signal integrity in RF-adjacent or high-speed data line termination. |
| Thermal Resistance (Rth j-a) | 320 K/W - defines temperature rise under free-air conditions on standard FR4 footprint. |
Pinout & Package
Encapsulated in the SOD123 plastic surface-mount package (2.675 mm × 1.6 mm × 1.15 mm body), the BAT46GWX features a two-terminal configuration with cathode marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar identifies this terminal - critical for correct orientation in reverse polarity protection. |
| 2 | Anode (A) | Connected to higher-potential source; serves as input for clamping or forward conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge robustness without increasing VF - validated per IEC 61000-4-2 Level 4. |
| Low forward voltage | 710 mV typical at 250 mA - directly lowers power loss in always-on protection paths. |
| Low reverse leakage | 1 µA typical at 75 V - maintains system sleep current below 5 µA in battery-powered sensors. |
| Small SMD footprint | SOD123 package - fits 2.5 mm² board area, compatible with 0402-class placement equipment. |
| Fast reverse recovery | 5.9 ns - prevents signal distortion in USB 2.0 or CAN FD bus termination networks. |
Applications
| High-Speed Switching | Line Termination |
|---|---|
Use Scenario: Fast-switching DC-DC converter synchronous rectification and flyback snubber paths. IC Role / Device Role: Low-loss unidirectional current steering element replacing slower PN diodes. Use Value: Reduces switching losses by 35% vs. 1N4148 due to sub-850 mV VF and near-zero Qrr. | Use Scenario: RS-485, CAN, and LVDS differential pair termination with transient suppression. IC Role / Device Role: Bidirectional clamping diode in parallel with TVS or as standalone line protector. Use Value: Limits overshoot to <1.2× VCC using 100 V VR margin while adding <40 pF loading. |
| Voltage Clamping | Reverse Polarity Protection |
Use Scenario: Input rail overvoltage suppression in 24 V industrial PLC I/O modules. IC Role / Device Role: Shunt clamp activated during transients exceeding nominal supply. Use Value: Clamps 100 V spikes with <5 ns response and dissipates ≤660 mW without derating. | Use Scenario: Battery input protection in portable medical monitors and handheld test equipment. IC Role / Device Role: Series-connected anode-to-load, cathode-to-battery positive rail. Use Value: Blocks reverse connection with <850 mV drop at full load - preserving >96% efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230P2T5G | 30 V VR, 200 mA IF, VF = 450 mV @ 200 mA - lower voltage, lower VF, smaller SOD-323 package. | Not suitable for 48–100 V clamping; limited to 3.3/5 V logic rail protection. | Select when ultra-low VF dominates over voltage rating and board space is constrained. |
| Vishay VS-2EDH02HM3/85A | 100 V VR, 2 A IF, VF = 820 mV @ 2 A - higher current, TO-277 package, no guard ring. | Over-specified for 250 mA use; requires larger layout and lacks integrated stress protection. | Select only if future design scaling to >1 A is certain and thermal mass justifies TO-277 footprint. |
Compared with NSR0230P2T5G and VS-2EDH02HM3/85A, BAT46GWX uniquely balances 100 V capability, SOD123 compactness, guard ring reliability, and 250 mA operation - making it optimal for space-constrained industrial and instrumentation designs requiring proven stress resilience.

FAQ
Is BAT46GWX qualified for automotive applications?
No. BAT46GWX is explicitly designated as non-automotive qualified per Nexperia's revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction. For automotive use, Nexperia offers the BAT46GW-Q variant with full AEC-Q101 compliance and enhanced HTOL testing.
What is the maximum allowable peak forward surge current for BAT46GWX?
The non-repetitive peak forward current (IFSM) is 2.5 A for tp < 10 ms square-wave pulses with Tj(init) = 25 °C. This rating assumes mounting on standard FR4 with single-sided copper and tin-plated pads - exceeding this value risks metallization failure or bond wire lift.
How does the guard ring affect BAT46GWX's ESD performance?
The integrated guard ring improves ESD robustness by distributing electric field gradients at the junction edge, raising the human-body model (HBM) rating to ±8 kV (per Nexperia internal characterization). This mitigates premature avalanche and enhances survivability during board handling and connector mating events.
Can BAT46GWX be used in place of BAT54 series diodes?
No - BAT54 devices are dual common-cathode Schottky diodes in SOT-23, while BAT46GWX is a single-diode SOD123 part. Electrically, BAT46GWX offers higher VR (100 V vs. 30 V) but lower IF (250 mA vs. 200 mA per anode), making direct substitution invalid without circuit revalidation and layout change.
