Product details
Overview
BAV19WS-G RRG from Taiwan Semiconductor is a surface-mount fast switching diode in SOD-323 package, rated for 120 V repetitive peak reverse voltage, 200 mA average rectified output current, and 625 mW power dissipation, used in general-purpose small-signal switching applications such as voltage clamping and signal routing in consumer power supplies.
For engineers reviewing the BAV19WS-G RRG datasheet, BAV19WS-G RRG pinout, BAV19WS-G RRG application, or BAV19WS-G RRG equivalent, key selection criteria include reverse recovery time (trr = 50 ns), forward voltage at 200 mA (VF = 1.25 V), junction capacitance (CJ = 2.5 pF), halogen-free green compound compliance, and SOD-323 mechanical compatibility with automated assembly.
Technical Context
This diode operates as a unidirectional semiconductor switch with low forward conduction loss and fast turn-off behavior enabled by optimized carrier lifetime control. Its 50 ns reverse recovery time supports operation up to several MHz in high-frequency rectification and waveform shaping circuits.
The SOD-323 package provides polarity identification via cathode band, moisture sensitivity level 1 handling, and thermal resistance of 200°C/W junction-to-ambient - enabling reliable performance in compact, thermally constrained PCB layouts without derating below 75°C ambient.
Key Specifications

| trr | 50 ns - measured at IF = IR = 30 mA, RL = 100 Ω, Irr = 0.1×IR; enables clean edge transitions in >1 MHz digital logic interfaces |
| CJ | 2.5 pF - junction capacitance at VR = 0 V, f = 1.0 MHz; minimizes signal distortion in RF detector and high-speed sampling circuits |
| VF | 1.25 V - forward voltage drop at IF = 200 mA; determines conduction loss and self-heating in battery-powered signal conditioning stages |
| PD | 625 mW - maximum power dissipation at TA = 25°C; sets thermal design margin before derating begins per Fig. 4 curve |
| RθJA | 200 °C/W - thermal resistance from junction to ambient; informs heatsinking requirements in sealed enclosures or stacked PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar small-signal switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV20WS-G RRG | Higher VRRM = 150 V; identical SOD-323 package, trr = 50 ns, VF = 1.25 V @ 200 mA | Preferred where system-level transients exceed 120 V but layout space and thermal constraints match BAV19WS-G RRG | Select when higher reverse standoff is required without changing board layout or thermal management |
| 1N4148W-7-F | VRRM = 100 V; trr = 4 ns (faster); VF = 1.25 V @ 100 mA; same SOD-123 package (not pin-compatible) | Better suited for ultra-fast digital signal steering; requires PCB pad redesign due to different footprint | Choose only if trr < 10 ns is mandatory and layout revision is acceptable |
Compared with BAV19WS-G RRG, BAV20WS-G RRG offers +30 V reverse margin with no trade-offs in speed or thermal performance, while 1N4148W-7-F delivers significantly faster recovery but demands mechanical redesign and accepts lower reverse voltage tolerance.

FAQ
What is the maximum reverse voltage rating for BAV19WS-G RRG?
The BAV19WS-G RRG has a repetitive peak reverse voltage (VRRM) rating of 120 V. This value is specified under standard test conditions (TA = 25°C) and represents the highest continuous reverse-bias voltage the diode can block without entering avalanche breakdown. Exceeding this rating risks irreversible junction damage, especially under transient conditions without proper clamping.
Does BAV19WS-G RRG meet halogen-free standards?
Yes, BAV19WS-G RRG uses green compound compliant with IEC 61249-2-21 and is RoHS 2011/65/EU compliant. The "G" suffix in the part number explicitly denotes halogen-free molding compound, verified through material certification and elemental analysis - no brominated or chlorinated flame retardants are present in the SOD-323 package body.
What is the reverse recovery time of BAV19WS-G RRG and how is it measured?
The reverse recovery time (trr) of BAV19WS-G RRG is 50 ns, measured under the condition: IF = IR = 30 mA, RL = 100 Ω, and Irr = 0.1 × IR (per Note 3 in DS_S0000021). This standardized test reflects real-world switching behavior in digital logic interfaces and high-frequency rectifiers, not idealized small-signal conditions.
Can BAV19WS-G RRG be used in place of 1N4148 in existing designs?
BAV19WS-G RRG is not a direct replacement for 1N4148 due to differences in package (SOD-323 vs. DO-35), VRRM (120 V vs. 100 V), and trr (50 ns vs. 4 ns). While both are general-purpose switching diodes, substituting BAV19WS-G RRG requires verifying layout compatibility, thermal margin at 625 mW, and whether 50 ns recovery meets timing requirements in the target circuit.
What is the thermal resistance of BAV19WS-G RRG and how does it affect PCB layout?
BAV19WS-G RRG has a junction-to-ambient thermal resistance (RθJA) of 200°C/W under standard JEDEC test conditions. This means each watt of dissipated power raises the junction temperature by 200°C above ambient - so at 200 mA and 1.25 V drop (250 mW), junction rise is ~50°C. Layout must avoid copper isolation and ensure ≥10 mm² of adjacent top-layer copper for passive cooling in sustained operation.
