Product details
Overview
BAW101-7 from Diodes Incorporated is a dual surface-mount switching diode in SOT143 package, featuring two electrically isolated diode elements with 300 V repetitive peak reverse voltage per element, 50 ns reverse recovery time, and 1.1 V max forward voltage at 100 mA - used in high-speed signal routing and DC-DC converter flyback protection.
For engineers reviewing the BAW101-7 datasheet, BAW101-7 pinout, BAW101-7 application, or BAW101-7 equivalent, this device supports fast-switching requirements in compact power management and RF signal path isolation where low capacitance (2.0 pF) and thermal robustness (–65°C to +150°C) are critical.
Technical Context
The BAW101-7 integrates two independent PN junction diodes in a single SOT143 package, enabling dual-channel switching without cross-coupling. Each diode exhibits 300 V VRRM, 50 ns tRR, and 2.0 pF total capacitance at 0 V, making it suitable for high-frequency clamp and snubber circuits.
Its thermal resistance of 312 °C/W (RθJA) and 400 mW total power dissipation support operation up to +150°C ambient when mounted on FR-4 with recommended pad layout. Reverse leakage remains ≤75 µA at 250 V and +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V per diode - supports 24 V–48 V industrial bus clamping and flyback voltage suppression |
| tRR | 50 ns - enables reliable operation in 1–5 MHz switching converters and RF detector circuits |
| CT | 2.0 pF at 0 V - minimizes signal distortion in UHF band (≤1 GHz) antenna switching paths |
| IF | 250 mA per diode - sufficient for logic-level signal steering and low-power rectification |
| RθJA | 312 °C/W - requires minimal PCB copper area for thermal relief in space-constrained modules |
| TJ Range | –65°C to +150°C - qualified for under-hood automotive and outdoor telecom equipment |
Pinout & Package
SOT143 package: 4-pin surface-mount plastic case (UL 94V-0), 2.90 mm × 1.92 mm footprint, 0.80 mm height, matte tin-plated leadframe, moisture sensitivity level 1.

| Pin 2 | Cathode of Diode 1 | Connected to ground or return path in clamp configuration; shares common cathode plane with Pin 4 in some layouts |
| Pin 3 | Anode of Diode 2 | Independent anode node - enables dual-rail or differential signal switching without shared bias |
| Pin 4 | Cathode of Diode 2 | Electrically isolated cathode; allows separate voltage referencing for each diode channel |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99-7-F | Same SOT143 package; 70 V VRRM, 4 ns tRR, 2.5 pF CT | Better for <100 MHz digital logic clamping; insufficient for 24 V+ power rail protection | Select when ultra-fast recovery (<5 ns) and low-voltage signal integrity outweigh voltage headroom needs. |
| MMBD1204-7-F | Same SOT143; 200 V VRRM, 50 ns tRR, 1.5 pF CT | Lower voltage rating limits use in 48 V systems; slightly lower capacitance improves HF isolation margin. | Choose for cost-sensitive 24 V telecom line cards where 200 V margin is acceptable and sub-2 pF capacitance is prioritized. |
Compared with BAV99-7-F and MMBD1204-7-F, the BAW101-7 uniquely balances 300 V standoff, 50 ns speed, and 2.0 pF capacitance - making it optimal for mid-voltage industrial power clamping where both ruggedness and RF performance matter.

FAQ
What is the maximum continuous forward current rating per diode in the BAW101-7?
The BAW101-7 supports 250 mA average forward current per diode under standard FR-4 mounting conditions. This rating assumes TA = 25°C and adheres to the recommended pad layout published by Diodes Incorporated. Derating applies above 25°C ambient per the 312 °C/W thermal resistance curve.
Can the BAW101-7 be used in series-connected configurations for higher voltage blocking?
Yes - the datasheet explicitly specifies 600 V series connection working peak reverse voltage. This requires matched diodes and balanced voltage division, typically achieved using equal parallel resistors (e.g., 1 MΩ each) across each diode to ensure static voltage sharing under DC or low-frequency conditions.
Is the SOT143 package of the BAW101-7 compatible with standard reflow profiles for lead-free soldering?
Yes - the BAW101-7 uses matte tin-plated leads and meets J-STD-020 moisture sensitivity level 1, allowing exposure to ambient indefinitely before reflow. It is qualified for standard Pb-free reflow profiles with peak temperatures up to 260°C and 60-second duration above 217°C, per Diodes' packaging specifications.
Does the BAW101-7 have a specified junction-to-case thermal resistance (RθJC)?
No - the official datasheet provides only RθJA = 312 °C/W (junction-to-ambient, FR-4 board). RθJC is not characterized or guaranteed for this SOT143 device, as thermal performance depends heavily on PCB copper area, layer stack-up, and airflow - all outside the device's controlled parameters.
