Product details
Overview
B190BE-13 from Diodes Incorporated is a 90 V, 1.0 A high-voltage Schottky barrier rectifier in SMB package, featuring 0.79 V max forward voltage at 1.0 A and 0.2 mA max reverse leakage at 25°C, optimized for polarity protection and DC-DC freewheeling in compact power supplies.
For engineers reviewing the B190BE-13 datasheet, B190BE-13 pinout, B190BE-13 application, or B190BE-13 equivalent, this device is selected for low-loss, high-frequency rectification where thermal resistance (75°C/W junction-to-ambient) and RoHS-compliant lead-free plating are critical design constraints.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and supports automated SMT assembly. Its 27 pF typical junction capacitance at 4 V and 1 MHz enables stable operation in high-frequency switching topologies up to several hundred kHz.
Rated for -55°C to +150°C operating temperature, it delivers 30 A non-repetitive surge current capability and maintains <5.0 mA reverse leakage at 125°C - enabling reliable use in thermally constrained industrial and automotive auxiliary power stages.
Key Specifications

| IO | 1.0 A - Continuous average forward current at TA = 25°C on FR-4 PCB |
| VF Max | 0.79 V @ IF = 1.0 A, TA = 25°C - Low conduction loss enabling >90% efficiency in 5–24 V DC-DC outputs |
| IR Max | 0.2 mA @ VR = 90 V, TA = 25°C - Minimal standby power drain in blocking configurations |
| RθJA | 75 °C/W - Thermal resistance with SMB package on standard 2 oz copper pad, defining heatsinking requirements |
| CT | 27 pF @ VR = 4 V, f = 1 MHz - Low junction capacitance supporting fast switching and reduced EMI in SMPS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB190-E3/54 (Vishay) | Same 90 V VRRM, 1.0 A IO, but VF = 0.85 V max at 1 A; SMB package identical | Higher VF increases conduction loss by ~75 mW at 1 A, requiring marginally larger thermal pad | Select when Vishay supply chain alignment or legacy qualification is required |
| SS19 (ON Semiconductor) | 90 V VRRM, 1.0 A IO, VF = 0.82 V max; SMB package, but IR = 0.5 mA max at 25°C | Higher leakage reduces suitability in battery-powered always-on circuits | Prefer for cost-sensitive consumer designs where 0.5 mA leakage is acceptable |
Compared with SB190-E3/54 and SS19, B190BE-13 offers the lowest VF (0.79 V) and tightest IR (0.2 mA), making it optimal for thermally constrained or ultra-low-quiescent-current applications demanding minimal forward drop and leakage.

FAQ
What is the maximum junction temperature for continuous operation of B190BE-13?
The B190BE-13 is rated for continuous operation from -55°C to +150°C junction temperature. Derating begins above 25°C ambient per Figure 4; at 75°C ambient, maximum DC forward current drops to approximately 0.6 A due to RθJA = 75°C/W and thermal limits.
Is B190BE-13 compatible with lead-free reflow soldering processes?
Yes - B190BE-13 features matte tin lead-free plating qualified to MIL-STD-202 Method 208 and supports standard Pb-free reflow profiles (peak 260°C, 10-second dwell). Its SMB package withstands JEDEC J-STD-020 Level 1 moisture sensitivity without baking.
How does the guard ring construction improve reliability in real-world applications?
The guard ring die structure mitigates edge breakdown under voltage transients, increasing surge immunity beyond standard Schottky designs. In practice, this allows the device to survive 30 A non-repetitive surges without degradation - critical in relay drivers and motor control flyback paths.
Can B190BE-13 replace B1100BE-13 in a 100 V blocking application?
No - B190BE-13 has 90 V VRRM and must not be substituted in circuits requiring 100 V blocking. Exceeding VRRM risks avalanche breakdown and premature failure. For 100 V applications, B1100BE-13 (100 V, 1.0 A, 0.79 V VF) is the correct selection with identical SMB footprint and thermal performance.
