Product details
Overview
BAV19WS RRG from Taiwan Semiconductor is a single-die, high-voltage SMD switching diode in SOD-323F package, rated for 120 V repetitive peak reverse voltage (VRRM), 200 mA average forward current (IF), and 1.25 V forward voltage at 200 mA - used in SMPS primary-side snubbers and DC/DC converter flyback clamping.
For engineers reviewing the BAV19WS RRG datasheet, BAV19WS RRG pinout, BAV19WS RRG application, or BAV19WS RRG equivalent, key selection criteria include verified VRRM = 120 V, IFSM = 2.5 A (1 µs), trr ≤ 50 ns, moisture sensitivity level 1, and RoHS-compliant halogen-free green compound.
Technical Context
This diode operates as a fast-recovery unidirectional switch with low stored charge and controlled reverse recovery behavior, enabling efficient energy transfer in high-frequency (>100 kHz) switching topologies. Its 5 pF junction capacitance at 0 V and 50 ns maximum reverse recovery time support stable operation in compact, high-density power stages.
The SOD-323F package provides thermal resistance of ~450°C/W (junction-to-ambient), and its matte tin-plated leads meet J-STD-002 solderability requirements. Polarity is marked by a cathode band, and the device is qualified to JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV20WS RRG | VRRM = 200 V (vs. 120 V); otherwise identical electrical and mechanical specs | Supports higher input voltage ranges (e.g., 230 V AC SMPS) but increases forward voltage margin | Select BAV20WS RRG only when system VIN transients exceed 120 V peak reverse stress on BAV19WS RRG |
| 1N4148W RRG | VRRM = 100 V, IF = 150 mA, trr = 4 ns - faster but lower voltage rating and surge capability | Better for signal-level switching; unsuitable for 120 V clamp or 200 mA power paths | Use 1N4148W RRG only in low-voltage (<80 V), low-current (<150 mA) logic or protection roles - not a drop-in replacement |
Compared with BAV20WS RRG and 1N4148W RRG, the BAV19WS RRG uniquely balances 120 V robustness, 200 mA current handling, and 50 ns recovery for cost-sensitive, high-volume SMPS snubbers where over-spec'ing voltage margin is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for BAV19WS RRG?
The BAV19WS RRG has a guaranteed VRRM of 120 V, verified per Taiwan Semiconductor's K2212 datasheet revision. This rating applies under standard test conditions (TA = 25°C, pulse testing), and the device maintains this specification across its full operating temperature range (−65°C to +150°C). The BAV19WS RRG is not rated for 200 V or 250 V - those values apply only to BAV20WS RRG and BAV21WS RRG respectively.
Is BAV19WS RRG RoHS compliant and halogen-free?
Yes, the BAV19WS RRG is RoHS compliant and halogen-free. The "G" suffix in the ordering code explicitly denotes green compound meeting IEC 61249-2-21 requirements. Taiwan Semiconductor confirms compliance in Version K2212 documentation, and the device carries no brominated flame retardants or chlorine-based additives in its SOD-323F molding compound.
What is the reverse recovery time (trr) of BAV19WS RRG, and under what conditions is it measured?
The BAV19WS RRG has a maximum reverse recovery time (trr) of 50 ns, measured under the standardized condition: IF = IR = 30 mA, RL = 100 Ω, and Irr = 3 mA. This value is specified at TA = 25°C and reflects the device's performance in high-frequency switching applications such as flyback snubbers and DC/DC converter outputs.
Does BAV19WS RRG require moisture baking before reflow soldering?
No, the BAV19WS RRG does not require moisture baking prior to reflow. It is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard lead-free reflow profiles (e.g., JEDEC J-STD-020) without preconditioning. This eliminates bake steps in high-volume SMT lines.
What is the marking code printed on the BAV19WS RRG device body?
The BAV19WS RRG is marked with the code "S5" on its SOD-323F package body. This marking is laser-etched or molded and appears adjacent to the cathode band. The "S5" identifier distinguishes it from BAV20WS RRG (marked "S6") and BAV21WS RRG (marked "S7"), enabling visual verification during incoming inspection and assembly traceability.
