Product details
Overview
BAT46WJ/DG/B2,115 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an ultra-compact SOD323F (SC-90) surface-mount package. It delivers 100 V reverse voltage rating, 710–850 mV forward voltage at 250 mA, and 5.9 ns reverse recovery time, enabling high-speed switching in space-constrained power rail clamping and polarity protection circuits.
For engineers reviewing the BAT46WJ/DG/B2,115 datasheet, BAT46WJ/DG/B2,115 pinout, BAT46WJ/DG/B2,115 application, or BAT46WJ/DG/B2,115 equivalent, key selection criteria include low VF under pulsed 250 mA load, sub-4 µA IR at 75 V, 39 pF capacitance at 1 MHz, and thermal resistance of 310 K/W (junction-to-ambient, FR4 standard footprint).
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against transient overvoltage and ESD stress without compromising switching speed. Its low forward voltage and fast trr stem from minimized minority-carrier storage and optimized metal-semiconductor interface design.
The device operates within −40 °C to +150 °C junction temperature range and is qualified for reflow soldering only. Thermal performance is specified for two mounting conditions: standard SOD323F footprint (Rth(j-a) = 310 K/W) and enhanced cathode pad (Rth(j-sp) = 35 K/W), enabling precise thermal budgeting in compact DC/DC and interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 100 V - supports input rail clamping up to 75 V DC with 25 V margin before breakdown |
| VF @ 250 mA | 710–850 mV - enables <150 mW conduction loss at full rated current, critical for efficiency in low-voltage rails |
| IR @ 75 V | 1–4 µA - ensures minimal leakage-induced offset in precision bias or sensing paths |
| trr | 5.9 ns - allows clean switching in >50 MHz digital line termination and flyback snubbing |
| Cd @ 1 V | 21 pF - limits capacitive loading on high-speed signal lines, preserving edge integrity |
| Ptot @ 25 °C | 400 mW - defines maximum steady-state dissipation on standard FR4 PCB without heatsinking |
| Rth(j-a) | 310 K/W - predicts ~93 °C junction rise above ambient at 300 mW dissipation on standard layout |
Pinout & Package
Encapsulated in the SOD323F (SC-90) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat lead, single-sided copper FR4 compatible. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for clamping and reverse polarity protection; connects to protected load or ground reference |
| 2 | Anode (A) | Input node for supply rail or signal source; carries forward current during conduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness (IFSM = 2.5 A) without increasing VF or trr, enabling reliable operation in noisy industrial environments |
| Low VF at 250 mA | 710–850 mV - reduces conduction loss by ≥30% vs. standard silicon diodes, extending battery life in portable devices |
| Ultra-low Cd | 21 pF at 1 V - minimizes signal distortion in USB, I²C, and CAN bus termination applications |
| SOD323F footprint | 1.7 mm × 1.25 mm area - fits into dense layouts where larger SOD-123 or SMA packages are prohibitive |
| Reflow-only assembly | Qualified per J-STD-020 - eliminates hand-soldering risk and ensures consistent intermetallic formation for long-term reliability |
Applications
| High-Speed Switching | Line Termination |
|---|---|
Use Scenario: Fast-switching DC/DC converter output rectification in point-of-load regulators. IC Role / Device Role / Timing Role: Low-loss freewheeling path during synchronous FET dead-time, minimizing voltage overshoot. Use Value: 5.9 ns trr prevents shoot-through risk and 710 mV VF cuts conduction loss by 40% vs. 1N5819 in 3.3 V/2 A rail. |
Use Scenario: RS-485 or CAN bus stub termination on compact industrial controllers. IC Role / Device Role / Timing Role: Bidirectional clamping element absorbing ESD transients while maintaining signal integrity. Use Value: 21 pF capacitance avoids signal edge degradation at 10 Mbps, and 100 V VR withstands ±36 V fault conditions. |
| Voltage Clamping | Reverse Polarity Protection |
Use Scenario: Input rail overvoltage suppression in battery-powered IoT sensors. IC Role / Device Role / Timing Role: Shunt clamp activated during transient surges (e.g., load dump), diverting excess energy to ground. Use Value: Guard ring ensures stable 100 V clamping threshold across temperature, with <4 µA leakage preserving standby current budget. |
Use Scenario: Reverse-battery protection in automotive accessory modules powered from 12 V systems. IC Role / Device Role / Timing Role: Series-blocking diode placed between battery connector and main regulator input. Use Value: 710 mV VF adds only 85 mV drop at 120 mA, avoiding brownout in microcontroller power domains during cold-crank conditions. |
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 NSR0230HT1G | Lower VR (30 V), higher VF (370 mV @ 200 mA), same SOD-323 package | Restricted to ≤24 V systems; unsuitable for 48 V clamping or 12 V reverse protection with high surge margin | Select when cost sensitivity outweighs voltage headroom needs and system max voltage is ≤24 V. |
| Vishay VS-2EDH01HM3/85A | Higher VR (100 V), higher VF (820 mV @ 250 mA), larger SOD-123 package (2.8 mm × 1.7 mm) | Same clamping capability but occupies 2.3× more PCB area; Rth(j-a) = 200 K/W improves thermal margin | Select when thermal derating dominates layout constraints and board space permits larger footprint. |
Compared with NSR0230HT1G and VS-2EDH01HM3/85A, BAT46WJ/DG/B2,115 uniquely balances 100 V capability, ultra-compact size, and sub-850 mV VF-making it optimal for space-limited 12–48 V systems requiring both surge resilience and low conduction loss.

FAQ
Is BAT46WJ/DG/B2,115 qualified for automotive applications?
No. Per Nexperia's revision history (v.3, October 2022), BAT46WJ was explicitly changed to non-automotive status. It lacks AEC-Q101 qualification, automotive-specific testing, and guaranteed PPAP documentation. For automotive use, select BAT46WJ-Q series variants with "-Q" suffix and verified AEC-Q101 compliance.
What is the maximum continuous forward current at 85 °C ambient?
At Tamb = 85 °C on a standard FR4 PCB (single-sided copper, tin-plated), the maximum average forward current is 0.18 A (Fig. 7). This derates from 0.25 A at 25 °C due to thermal resistance limitations-designers must verify junction temperature does not exceed 150 °C using Rth(j-a) = 310 K/W.
Can BAT46WJ/DG/B2,115 be hand-soldered?
No. The datasheet explicitly states "reflow soldering is the only recommended soldering method" (Section 8, Note [2]). Hand-soldering risks thermal damage to the die or bond wires due to localized overheating and violates Nexperia's qualified process-use stencil-printed paste and controlled reflow profile per J-STD-020.
How does the guard ring affect electrical performance?
The integrated guard ring enhances voltage standoff and ESD robustness without altering forward conduction or switching parameters. It suppresses edge breakdown at the PN junction periphery, allowing full 100 V VR rating while maintaining typical VF and trr values-verified in limiting values (Table 5) and characteristics (Table 7) under pulsed test conditions.
