Product details
Overview
BAT54GWJ from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD123 surface-mount package. It delivers 30 V reverse voltage rating, 200 mA forward current capability, ≤400 mV forward voltage at 10 mA, ≤2 µA reverse leakage at 25 V, and 10 pF capacitance at 1 V - enabling ultra-high-speed switching in automotive signal line termination.
For engineers reviewing the BAT54GWJ datasheet, BAT54GWJ pinout, BAT54GWJ application, or BAT54GWJ equivalent, key selection criteria include AEC-Q101 qualification, low VF/IR trade-off, thermal resistance (Rth(j-a) = 350 K/W), SOD123 footprint compatibility, and junction temperature limit of 150 °C.
Technical Context
This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ESD and transient overvoltage robustness. Its low-barrier metal-semiconductor junction enables fast recovery (no minority-carrier storage) and minimal reverse recovery charge.
The device operates within −55 °C to +150 °C ambient range and is rated for 600 mA non-repetitive peak forward current. Thermal performance is defined for two mounting conditions: standard FR4 footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (Rth(j-sp) = 58 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum DC blocking capability without breakdown; defines safe operating margin in 24 V automotive bus clamping. |
| Forward Current (IF) | 200 mA continuous - Sustained conduction level compatible with logic-level signal routing and low-power bias networks. |
| Forward Voltage (VF) | ≤400 mV at 10 mA - Minimizes power loss and self-heating in high-frequency switching paths. |
| Reverse Leakage (IR) | ≤2 µA at 25 V - Ensures signal integrity in high-impedance termination and sensing circuits. |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - Supports >100 MHz signal integrity in USB, LVDS, and CAN FD stub termination. |
| Junction Temperature (Tj) | 150 °C max - Enables operation in under-hood automotive environments with validated thermal derating curves. |
Pinout & Package
The BAT54GWJ is supplied in the SOD123 plastic surface-mount package (3.75 × 2.55 × 1.3 mm), featuring a standardized 2-pin layout with cathode identification via a molded marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked side of package; connects to ground or lower-potential node in clamp/rectifier configurations. |
| 2 | Anode (A) | Positive terminal; unmarked side; interfaces with signal source or higher-potential rail in forward-biased operation. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ruggedness against ESD and localized avalanche during line transients without increasing VF. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics per stress test requirements. |
| Low thermal resistance (Rth(j-sp)) | 58 K/W to solder point - Enables efficient heat transfer when cathode pad is enlarged on PCB. |
| Small SOD123 footprint | Compatible with 0805-class board space; supports automated placement and reflow without tombstoning risk. |
Applications
| Automotive CAN FD Bus Termination | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Bidirectional signal line protection on 5 Mbps CAN FD networks exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Passive clamping diode placed between CANH/CANL and VCC/GND rails to shunt transients below 30 V threshold. Use Value: Prevents receiver IC damage while maintaining <10 pF loading to preserve signal edge rate and eye diagram integrity. | Use Scenario: ESD protection for D+ and D− lines in portable USB host/device ports subjected to ±8 kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance steering diode routing surge current to VBUS or GND during IEC 61000-4-2 events. Use Value: Limits signal distortion with 10 pF capacitance and responds within nanoseconds due to Schottky zero-recovery behavior. |
| Industrial Sensor Signal Conditioning | Low-Power Logic-Level Translation |
Use Scenario: Biasing and level-shifting analog sensor outputs (e.g., thermistor bridges) into microcontroller ADC inputs. IC Role / Device Role / Timing Role: Forward-conducting diode establishing precise 0.3–0.4 V offset or clamping reference voltage in passive networks. Use Value: Delivers stable forward drop across −40 °C to +125 °C with <2 µA leakage preserving high-impedance node accuracy. | Use Scenario: Interfacing 3.3 V logic outputs to 5 V tolerant inputs in mixed-voltage embedded systems. IC Role / Device Role / Timing Role: Level-shifting diode in series with pull-up resistor to translate logic HIGH from 3.3 V to ~2.9 V at 5 V rail. Use Value: Enables reliable communication without active translators; 200 mA IF rating supports multiple fan-out loads. |
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; VF = 450 mV @ 10 mA; IR = 5 µA @ 25 V; not AEC-Q101 qualified. | Lacks automotive qualification; higher leakage reduces suitability for precision biasing. | Select when cost sensitivity outweighs AEC-Q101 requirement and leakage tolerance >5 µA. |
| Vishay VS-2EDH01HM3/85A | SOD-323 package; VR = 30 V; IF = 200 mA; VF = 370 mV @ 10 mA; IR = 1 µA @ 25 V; AEC-Q101 qualified. | Smaller footprint (1.7 × 1.25 mm); higher thermal resistance (Rth(j-a) = 450 K/W) limits power handling. | Prefer for space-constrained layouts where 0.3 V lower VF justifies reduced thermal margin and tighter placement. |
Compared with BAT54GWJ, NSS40201MR6T1G trades automotive qualification for slightly higher VF and IR, while VS-2EDH01HM3/85A offers better VF/IR but sacrifices thermal performance and board area flexibility due to smaller SOD-323 size.

FAQ
Is BAT54GWJ suitable for bidirectional ESD protection?
No - BAT54GWJ is a single anode-cathode Schottky diode and provides unidirectional clamping only. For bidirectional protection, two BAT54GWJ devices must be used in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated dual-rail TVS like PESD5V0S1BA should be selected.
What is the maximum allowable PCB copper area for optimal thermal performance?
Per Nexperia's data sheet, a 1 cm² copper pad connected to the cathode (Pin 1) reduces Rth(j-sp) to 58 K/W. Larger pads yield diminishing returns; no specification exceeds 1 cm². Standard footprint (no extended pad) yields Rth(j-a) = 350 K/W on single-sided FR4.
Does the "G9" marking correspond to BAT54GWJ?
Yes - Table 4 confirms BAT54GW is marked "G9" on the SOD123 package. The "J" suffix in BAT54GWJ denotes tape-and-reel packaging per ordering code BAT54GW,115 (10,000 pcs/reel), not a functional variant.
Can BAT54GWJ replace BAT54C in existing designs?
Only with layout review - BAT54C uses SOT-23 (3-pin) packaging with anode/cathode/anode configuration, while BAT54GWJ is SOD123 (2-pin) with anode/cathode. Pin count, footprint, and thermal path differ significantly; direct replacement requires PCB redesign and validation of VF/IR performance at system operating conditions.
