Product details
Overview
BAV199DW-7-F from Diodes Incorporated is a quad surface-mount low-leakage switching diode in SOT363 package, featuring 85 V peak reverse voltage, ≤5 nA leakage at 75 V, and 3.0 µs reverse recovery time. It integrates four independent diodes in one compact footprint for signal routing, level shifting, and protection in high-density analog and digital interface circuits.
For engineers reviewing the BAV199DW-7-F datasheet, BAV199DW-7-F pinout, BAV199DW-7-F application, or BAV199DW-7-F equivalent, key selection criteria include ultra-low IR (5 nA @ 75 V), fast tRR (3.0 µs), dual-channel layout compatibility, and RoHS-compliant lead-free plating on SOT363 terminals.
Technical Context
This quad diode array uses planar epitaxial construction to achieve stable low-leakage performance across -65°C to +150°C operating range. Each diode exhibits matched forward voltage (VF ≤ 1.25 V @ 150 mA) and consistent junction capacitance (CT = 1.5 pF @ 0 V, 1 MHz).
The SOT363 package enables high-density placement with thermal resistance RθJA = 625°C/W on FR-4 board, supporting per-element power dissipation up to 200 mW. Polarity is defined by top-view marking (K52 YM) and internal AC/AC/C2/A1/A2/C1 schematic orientation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports DC blocking in 24–48 V industrial control signal paths without breakdown |
| IR @ 75 V | 5.0 nA - ensures minimal signal crosstalk in precision sensor front-ends and sample-hold circuits |
| tRR | 3.0 µs - enables reliable operation in <300 kHz switching applications like clamping and waveform shaping |
| VF @ 150 mA | 1.25 V - limits forward conduction loss to <187.5 mW per diode under max rated current |
| CT @ 0 V | 1.5 pF - preserves signal integrity in RF detector and high-speed logic interface applications |
| PD (total) | 200 mW - defines maximum combined power handling across all four diodes on standard FR-4 layout |
| TJ Range | -65°C to +150°C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment |

IC Role / Device Role / Timing Role: Bidirectional level shifter using back-to-back diode configuration with pull-up resistors. Use Value: Matched VF (≤1.25 V @ 150 mA) ensures symmetric rise/fall timing skew <1 ns across 100 kbps control signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage quad diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7-F | Same SOT363 package; VRRM = 70 V; IR = 10 nA @ 75 V (2× higher leakage) | Not suitable for >60 V signal rails or sub-µA bias networks | Select when cost sensitivity outweighs leakage or voltage margin requirements |
| MMBD1204-7-F | VRRM = 100 V; IR = 100 pA @ 20 V (lower leakage at low VR); tRR = 4.0 µs | Better for ultra-low-current photodiode biasing; slower recovery limits >200 kHz use | Prefer for precision analog sensing where VR < 30 V and speed < 150 kHz |
Compared with BAV99DW-7-F and MMBD1204-7-F, BAV199DW-7-F uniquely balances 85 V rating, 5 nA leakage, and 3.0 µs tRR-making it optimal for industrial I/O modules requiring both robustness and signal fidelity.

FAQ
What is the maximum continuous forward current per diode in the BAV199DW-7-F?
The BAV199DW-7-F supports 160 mA continuous forward current per diode at TA = +25°C, derating linearly to 0 mA at +150°C per the current derating curve in Figure 4. This rating assumes mounting on FR-4 with Diodes Incorporated's recommended pad layout (AP02001) to maintain thermal performance.
Does the BAV199DW-7-F have polarity markings on the package?
Yes-the SOT363 package features top-side laser marking "K52" as the product type code and a two-character date code (e.g., "C9" for September 2015). Pin 1 (A1) is located at the end nearest the marking, with polarity confirmed by the internal schematic showing anode/cathode orientation per diode pair.
Can the BAV199DW-7-F be used in place of a single BAV199 in a design?
No-the BAV199DW-7-F contains four independent diodes in SOT363, whereas the single-diode BAV199 uses SOT23. Pin count, footprint, and internal connectivity differ fundamentally. Substitution requires PCB layout revision and verification of per-diode thermal dissipation under combined loading.
Is the BAV199DW-7-F suitable for high-frequency RF detection applications?
Yes-its 1.5 pF junction capacitance at 0 V and 3.0 µs reverse recovery time support RF detection up to ~300 MHz in envelope detector configurations. However, for >1 GHz applications, dedicated Schottky diodes with sub-0.5 pF CT and <1 ns tRR are recommended instead.
