Product details
Overview
BAS19W RVG from Taiwan Semiconductor is a surface-mount small-signal switching diode in SOT-323 package, rated for 150 V peak repetitive reverse voltage, 200 mA average rectified current, and 625 mW power dissipation, with 4 ns reverse recovery time-used in general-purpose DC-DC converter flyback clamping and signal routing circuits.
For engineers reviewing the BAS19W RVG datasheet, BAS19W RVG pinout, BAS19W RVG application, or BAS19W RVG equivalent, key selection criteria include reverse recovery time (trr = 4 ns), forward voltage at 30 mA (VF = 1.0 V), junction-to-ambient thermal resistance (RθJA = 200 °C/W), moisture sensitivity level (MSL 1), and RoHS-compliant green compound packaging.
Technical Context
The BAS19W RVG operates as a fast-switching unidirectional PN junction diode optimized for high-frequency switching applications up to several MHz. Its low trr (4 ns) and low diode capacitance (CD = 5 pF at VR = 0 V, f = 1 MHz) enable minimal switching loss and reduced ringing in inductive load commutation.
Thermally, it supports continuous operation from –55 °C to +150 °C junction temperature, with derated power dissipation above 25 °C ambient per the defined curve (625 mW @ TA = 25 °C, linearly decreasing to 0 mW at TA = 150 °C). The SOT-323 package provides MSL 1 handling and 260 °C/10 s soldering tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in flyback snubber or polarity protection. |
| IF(AV) | 200 mA - Average forward current rating; sets continuous conduction limit in low-power switching paths. |
| trr | 4 ns - Reverse recovery time; enables efficient operation in >1 MHz DC-DC converters and high-speed logic interface clamping. |
| VF @ 30 mA | 1.0 V - Forward voltage drop; determines conduction loss and self-heating under typical bias conditions. |
| RθJA | 200 °C/W - Junction-to-ambient thermal resistance; used to calculate max junction temperature rise on standard PCB pad layout. |
| CD @ 0 V | 5 pF - Diode capacitance at zero bias; impacts high-frequency signal integrity and switching node oscillation risk. |
Pinout & Package
SOT-323 (SC-70) three-terminal plastic package: compact 2.2 × 1.35 × 0.9 mm outline, MSL 1, lead-free, green compound, 5 mg weight, compatible with standard reflow profiles including 260 °C/10 s peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to higher-potential node during conduction; requires trace width and copper area sufficient for 200 mA continuous current. |
| Cathode (K) | Forward current exit point / reverse voltage reference | Typically tied to ground or low-side switch node; serves as voltage clamp reference in flyback topologies. |
| Case / Heat Sink (not electrically isolated) | Package body (non-terminated) | Not internally connected; mechanical mounting only-no electrical function or thermal path beyond ambient convection. |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | trr = 4 ns enables use in >1 MHz switching regulators without excessive turn-off loss or voltage overshoot. |
| Low forward voltage | VF = 1.0 V @ 30 mA reduces conduction loss and improves efficiency in low-voltage, high-duty-cycle applications. |
| Small footprint SOT-323 | 2.2 × 1.35 mm outline saves board space in dense portable and IoT power management layouts. |
| MSL 1 handling | No dry-pack or baking required prior to assembly-simplifies manufacturing logistics and reduces process cost. |
Applications
| DC-DC Converter Snubber | Signal-Level Clamping |
|---|---|
Use Scenario: Clamp voltage spikes across MOSFET drains in 500 kHz–2 MHz buck-boost converters. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode absorbing inductive energy during switch turn-off. Use Value: 4 ns trr minimizes tail current and limits peak drain voltage to ≤150 V, protecting primary-side switches. | Use Scenario: Limit logic signal excursions beyond supply rails in mixed-voltage FPGA I/O interfaces. IC Role / Device Role / Timing Role: Bidirectional ESD/clamp diode (anode to GND, cathode to rail) providing sub-ns response. Use Value: 5 pF capacitance avoids signal distortion at 10–50 MHz data rates while maintaining 150 V standoff. |
| Reverse Polarity Protection | Peak Detector Circuit |
Use Scenario: Block reverse battery connection in 3.3–12 V portable electronics with minimal voltage drop. IC Role / Device Role / Timing Role: Series-connected anode-in blocking diode in main power path. Use Value: 1.0 V VF at 200 mA yields <200 mW loss at full load-acceptable for low-power battery systems. | Use Scenario: Capture positive voltage peaks in analog sensor conditioning front-ends (e.g., thermocouple amplifiers). IC Role / Device Role / Timing Role: Low-capacitance, low-leakage sampling diode charging hold capacitor. Use Value: IR = 0.1 µA @ 100 V ensures <1% droop over 100 ms hold time with 10 nF capacitor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS1C200MZ4T1G | VRRM = 200 V, trr = 4 ns, VF = 1.1 V @ 200 mA, SOT-323 | Higher reverse voltage rating; identical speed and package; slightly higher VF increases conduction loss. | Preferred where ≥200 V blocking is required; otherwise BAS19W RVG offers lower VF at 150 V use cases. |
| Diodes Incorporated BAV21W-7-F | VRRM = 250 V, trr = 50 ns, VF = 1.0 V @ 200 mA, SOT-323 | Slower recovery (50 ns vs. 4 ns); suitable for ≤100 kHz switching but not high-frequency SMPS. | Select BAS19W RVG when trr < 10 ns is mandatory; choose BAV21W-7-F only for cost-sensitive, low-frequency clamping. |
Compared with NSS1C200MZ4T1G and BAV21W-7-F, the BAS19W RVG delivers optimal balance of low VF (1.0 V), ultrafast trr (4 ns), and 150 V rating-making it ideal for compact, high-efficiency 1–2 MHz DC-DC stages where both speed and conduction loss matter.

FAQ
What is the maximum junction temperature rating for BAS19W RVG?
The BAS19W RVG has a specified junction temperature range of –55 °C to +150 °C. This allows reliable operation in automotive under-hood environments and industrial power supplies where ambient temperatures exceed 85 °C. Derating begins at 25 °C ambient, with power dissipation linearly decreasing to zero at 150 °C case temperature. The BAS19W RVG must be mounted on a PCB with adequate copper area to maintain TJ ≤ 150 °C under worst-case load.
Is BAS19W RVG pin-compatible with BAS20W or BAS21W?
Yes, the BAS19W RVG shares identical SOT-323 package dimensions, pin configuration (anode–cathode–case), and mechanical footprint with BAS20W and BAS21W. However, their electrical ratings differ: BAS20W has VRRM = 200 V, BAS21W has VRRM = 250 V, while BAS19W RVG is rated at 150 V. All three exhibit the same 4 ns trr and 1.0 V VF @ 30 mA, making them drop-in replacements where voltage margin permits.
What does "RVG" signify in BAS19W RVG?
"RVG" is Taiwan Semiconductor's packing and marking code: "RV" denotes the manufacturing site and process control, and "G" indicates green compound (lead-free, RoHS-compliant encapsulant). It appears as the top-side laser marking on the SOT-323 package and corresponds to ordering code BAS19W RVG-distinct from BAS19W-M0 RVG (which adds tape-and-reel variant coding). The BAS19W RVG meets JEDEC MSL 1 and 260 °C/10 s soldering requirements.
Does BAS19W RVG require special handling due to moisture sensitivity?
No-BAS19W RVG is rated Moisture Sensitivity Level 1 (MSL 1), meaning it may be stored indefinitely at ≤30 °C/85 % RH without dry-packaging or baking. This eliminates pre-reflow baking steps and simplifies SMT line integration. The SOT-323 package uses green compound with robust moisture barrier properties, fully compliant with IPC/JEDEC J-STD-020D. The BAS19W RVG can be placed directly from reel into standard reflow ovens.
How is thermal performance characterized for BAS19W RVG on a standard PCB?
Thermal performance of BAS19W RVG is specified as RθJA = 200 °C/W on a standard JEDEC 2S2P test board (1 in² copper pad, 1 oz Cu). In real designs, actual junction temperature depends on local copper area, airflow, and adjacent heat sources. For example, with 200 mA IF and 1.0 V VF, power dissipation is 200 mW; at RθJA = 200 °C/W, ΔTJ = 40 °C above ambient. To ensure TJ ≤ 150 °C, keep ambient below 110 °C-or increase copper area to reduce RθJA. The BAS19W RVG datasheet includes Fig. 3 (Power Derating Curve) for precise derating guidance.
