Product details
Overview
BAV99HDWQ-7 from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, rated for 100 V peak reverse voltage, 200 mA continuous forward current, and 4.0 ns reverse recovery time. It integrates two independent BAV99 circuits for compact signal routing in automotive-level ESD-protected interfaces.
For engineers reviewing the BAV99HDWQ-7 datasheet, BAV99HDWQ-7 pinout, BAV99HDWQ-7 application, or BAV99HDWQ-7 equivalent, key selection criteria include reverse breakdown voltage, low capacitance (1.5 pF), AEC-Q101 qualification, thermal resistance (260 °C/W junction-to-solder point), and dual-diode integration in a 6-pin surface-mount package.
Technical Context
This dual diode array implements two independent, isolated silicon planar epitaxial switching diodes in a single SOT363 package. Each element features 100 V VRRM, 0.715 V typical forward voltage at 1 mA, and sub-5 ns tRR under 10 mA test conditions.
The device is optimized for high-reliability automotive signal conditioning: it meets AEC-Q101 stress testing requirements, supports operation from –65 °C to +150 °C, and delivers <0.5 µA leakage at 80 V reverse bias and 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands transient spikes up to 100 V without breakdown in signal path protection |
| tRR | 4.0 ns - Enables clean switching in >100 MHz digital or RF signal routing applications |
| CT | 1.5 pF @ 0 V - Minimizes signal distortion and loading in high-frequency data lines |
| IF | 200 mA continuous - Supports sustained current in level-shifting or clamping circuits |
| RθJSP | 260 °C/W - Enables reliable thermal performance with standard FR-4 PCB layout and solder-point heatsinking |
| IR | 0.5 µA @ 80 V - Ensures low standby power loss in always-on sensing or interface circuits |
Pinout & Package
SOT363 6-pin surface-mount package with exposed leadframe; dimensions: 2.15 mm × 2.10 mm × 1.00 mm (L × W × H); moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first diode's forward conduction path |
| 2 (C1) | Cathode of Diode 1 | Output/return node for Diode 1; tied to common reference plane |
| 3 (A2) | Anode of Diode 2 | Independent input node for second diode's forward path |
| 4 (C2) | Cathode of Diode 2 | Independent output node for Diode 2; electrically isolated from C1 |
| 5 (AC1) | Anode Common (shared) | Internally connected anode node for both diodes - used in common-anode configuration |
| 6 (AC2) | Cathode Common (shared) | Not present - AC2 is mislabeled in some diagrams; actual SOT363 pin 6 is cathode of Diode 2 (C2) per internal schematic and top view |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent diodes in one package | Reduces board space by ~40% vs. two discrete SOT23 diodes; enables matched timing in differential paths |
| AEC-Q101 qualified | Validated for automotive-grade temperature cycling, humidity, and mechanical shock per industry reliability standard |
| Low 1.5 pF capacitance | Maintains signal integrity on USB 2.0, CAN FD, or LVDS lines without added impedance discontinuity |
| 0.715 V VF @ 1 mA | Enables low-voltage logic-level clamping down to 1.8 V I/O rails without excessive forward drop |
| Halogen- and antimony-free "Green" construction | Complies with EU Directive 2011/65/EU and automotive material restrictions (Br+Cl <1500 ppm, Sb <1000 ppm) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7 | Same SOT363 package and dual-diode topology but not AEC-Q101 qualified; 5.0 ns tRR vs. 4.0 ns | Limited to industrial/commercial temperature range (–55 °C to +150 °C) and non-automotive use cases | Select when AEC-Q101 compliance is unnecessary and cost optimization is prioritized |
| NSR0230P2T5G | Single 30 V Schottky diode in SOD-523; no dual configuration; 0.35 V VF but only 30 V VRRM | Not suitable for 100 V rail protection; used in low-voltage DC-DC feedback or USB power path | Choose only for sub-30 V systems requiring ultra-low forward drop, not for BAV99HDWQ-7 functional replacement |
Compared with BAV99DW-7 and NSR0230P2T5G, the BAV99HDWQ-7 uniquely combines AEC-Q101 qualification, 100 V rating, and 4.0 ns switching in a dual-diode SOT363 - making it irreplaceable for automotive signal-line protection where reliability and voltage margin are non-negotiable.

FAQ
What is the maximum operating temperature for BAV99HDWQ-7?
The BAV99HDWQ-7 is rated for junction and storage temperatures from –65 °C to +150 °C. Its thermal resistance junction-to-solder point is 260 °C/W, enabling full-rated operation at +125 °C ambient when mounted per Diodes' recommended SOT363 pad layout on FR-4 PCB.
Is BAV99HDWQ-7 pin-compatible with standard BAV99 dual-diode packages?
Yes - BAV99HDWQ-7 uses the industry-standard SOT363 footprint and pinout (pins 1–2 and 3–4 as independent anode-cathode pairs, pin 5 as common anode). It replaces legacy BAV99 variants without PCB redesign, provided the AEC-Q101 qualification and tighter tRR spec meet system requirements.
Does BAV99HDWQ-7 support bidirectional ESD protection?
No - the BAV99HDWQ-7 contains two unidirectional switching diodes. For bidirectional ESD clamping, external series resistors and TVS diodes are required. Its internal structure supports only forward-biased clamping from anode to cathode per element, not symmetrical ±VBR behavior.
How does the 1.5 pF capacitance affect high-speed signal routing?
At 1.5 pF per diode, the BAV99HDWQ-7 introduces negligible capacitive loading on 50 Ω transmission lines - causing <0.1 dB insertion loss at 500 MHz and preserving rise times >700 ps. This enables direct placement on USB 2.0, CAN FD, and LVDS traces without signal integrity degradation.
