Product details
Overview
BAT46GWJ 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 space-constrained DC/DC converters and USB power paths.
For engineers reviewing the BAT46GWJ datasheet, BAT46GWJ pinout, BAT46GWJ application, or BAT46GWJ equivalent, key selection criteria include its low VF/IR trade-off, SOD123 thermal performance (Rth(j-a) = 320 K/W), junction temperature limit of 150 °C, and cathode-marked polarity alignment in automated assembly.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its low barrier height enables fast carrier injection and extraction, resulting in sub-6 ns trr and minimal stored charge - critical for high-frequency flyback snubbers and synchronous rectifier freewheeling paths.
The device operates within −55 °C to +150 °C ambient range and exhibits strong temperature stability: VF increases only ~150 mV from −40 °C to +125 °C at 50 mA, while IR remains below 600 µA even at 100 V and 85 °C - supporting reliable operation in industrial power supplies and automotive body-control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports input clamping in 48 V telecom systems and 24 V industrial rails without avalanche risk. |
| Forward Current (IF) | 250 mA continuous - suitable for low-power signal path protection and auxiliary supply rectification. |
| Forward Voltage (VF) | 710–850 mV @ 250 mA - reduces conduction loss by >30 % vs. standard PN diodes in 3.3 V/5 V logic-level circuits. |
| Reverse Leakage (IR) | 1–4 µA @ 75 V - ensures minimal standby current in battery-backed real-time clocks and sensor bias networks. |
| Reverse Recovery (trr) | 5.9 ns - enables clean switching at >10 MHz in RF detector circuits and ESD clamp discharge paths. |
| Capacitance (Cd) | 39 pF @ 0 V - maintains signal integrity in high-speed data line termination (e.g., RS-485, CAN FD stubs). |
| Junction Temp (Tj) | 150 °C max - allows operation in sealed enclosures with limited airflow, such as smart meter housings. |
Pinout & Package
Encapsulated in the SOD123 plastic surface-mount package (2.675 mm × 1.6 mm × 1.15 mm), BAT46GWJ features a compact, low-profile footprint compatible with standard reflow soldering profiles and wave-solderable PCB layouts per Nexperia's recommended land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side with bar; connects to lower-potential node - must be routed to ground or return path for clamping and polarity protection functions. |
| 2 | Anode (A) | Unmarked terminal; connects to higher-potential source - used for forward conduction into load or reverse blocking from supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge breakdown under voltage transients - improves reliability in unregulated input stages without external TVS. |
| Low VF / IR balance | 710 mV VF and 1 µA IR at 25 °C enable efficient clamping with negligible quiescent loss in always-on circuits. |
| SOD123 thermal design | Rth(j-sp) = 190 K/W to cathode solder point - facilitates heat transfer through PCB copper pour for sustained 250 mA operation. |
| Fast trr & low Cd | 5.9 ns recovery + 39 pF capacitance - minimizes ringing and timing skew in high-speed digital I/O protection networks. |
Applications
| High-Speed Switching | Line Termination |
|---|---|
Use Scenario: Flyback converter secondary-side rectification in 5–12 V isolated auxiliary supplies. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; handles repetitive 250 mA pulses with <6 ns turn-off. Use Value: Low VF reduces conduction loss by 0.18 W vs. 1 V diode at 250 mA, improving efficiency in compact wall adapters. | Use Scenario: RS-485 bus stub termination on multi-drop communication lines. IC Role / Device Role / Timing Role: Bidirectional clamping diode limiting differential voltage swing to ±12 V while preserving signal edge fidelity. Use Value: 39 pF capacitance and 5.9 ns trr prevent signal distortion up to 25 Mbps, meeting TIA-485-A timing budgets. |
| Voltage Clamping | Reverse Polarity Protection |
Use Scenario: Input rail overvoltage suppression in 24 V industrial PLC I/O modules. IC Role / Device Role / Timing Role: Shunt clamp activated during surge events; absorbs energy until upstream fuse opens. Use Value: 100 V VR rating and guard ring ensure stable clamping without premature breakdown during 1 kV EFT bursts. | Use Scenario: Battery-input protection in portable medical sensors powered by CR2032 coin cells. IC Role / Device Role / Timing Role: Series-connected anode-to-load, blocking reverse current when battery is inserted backward. Use Value: 1 µA IR at 3 V ensures <1 nA leakage - extends 10-year shelf life of battery-powered devices. |
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 NSS40201MR6T1G | Same SOD-123 package; 40 V VR, 200 mA IF, 500 mV VF - lower voltage rating but lower forward drop. | Not suitable for 48 V or 24 V clamping; limited to 3.3/5 V logic rails and low-voltage battery inputs. | Select when VF < 500 mV is prioritized over VR > 70 V and system voltage stays below 20 V. |
| Vishay VS-2EDH01HM3/85A | SOD-123; 100 V VR, 250 mA IF, 820 mV VF, 100 pF Cd - higher capacitance and slower trr (12 ns). | Acceptable for DC/DC output rectification but unsuitable for >5 Mbps data line termination due to excessive Cd. | Choose only if cost sensitivity outweighs signal integrity requirements in non-high-speed applications. |
Compared with BAT46GWJ, NSS40201MR6T1G trades 60 V VR headroom for 210 mV lower VF in low-voltage logic protection, while VS-2EDH01HM3/85A sacrifices 39 pF capacitance and 5.9 ns speed for marginally better thermal resistance - making BAT46GWJ optimal for mixed-signal systems needing both robust clamping and clean signal edges.

FAQ
What is the maximum allowable junction temperature for BAT46GWJ?
The absolute maximum junction temperature is 150 °C, verified per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier and increased IR. Derating is required above 85 °C ambient - e.g., at 100 °C Tamb, maximum IF drops to ~180 mA based on Rth(j-a) = 320 K/W and Ptot derating curves.
Does BAT46GWJ have automotive qualification?
No. Per Nexperia's revision history (v.2, 20241009), BAT46GWJ is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is not warranted for use in safety-critical or engine-bay environments. Automotive alternatives require the "-Q" suffix (e.g., BAT46GW-Q).
How is cathode polarity identified on the BAT46GWJ package?
The cathode is marked by a visible bar on the top surface aligned with Pin 1, matching the SOD123 outline in Figure 8. This bar corresponds to the cathode terminal in Table 2 and must connect to the lower-potential node - e.g., ground in reverse polarity protection or the output rail in clamping configurations.
Can BAT46GWJ replace BAT54 series diodes in existing designs?
Only with verification. BAT46GWJ has higher VR (100 V vs. 30 V) and lower IF (250 mA vs. 200 mA avg), but shares SOD123 footprint and cathode-bar marking. Key differences include 5.9 ns trr (vs. ~5 ns for BAT54) and 39 pF Cd (vs. ~10 pF for BAT54). Layout changes may be needed for thermal relief and EMI control in high-frequency applications.
