Product details
Overview
BAV99TQ-13-F from Diodes Incorporated is a dual high-speed switching diode in SOT523 package, configured as two independent anode-cathode pairs sharing a common cathode connection (dual-common-cathode topology), with 85 V peak repetitive reverse voltage, 155 mA forward current per diode, and 4.0 ns reverse recovery time. It is AEC-Q101 qualified and manufactured in IATF16949-certified facilities for automotive signal routing and protection circuits.
For engineers reviewing the BAV99TQ-13-F datasheet, BAV99TQ-13-F pinout, BAV99TQ-13-F application, or BAV99TQ-13-F equivalent, key selection criteria include reverse recovery speed, leakage at elevated temperature, total capacitance at zero bias, and automotive qualification status - all confirmed in Diodes' DS30260 Rev. 13–2.
Technical Context
This dual diode operates with independent forward conduction paths and shared cathode termination, enabling compact clamping and steering functions in space-constrained PCB layouts. Its ultra-fast 4.0 ns trr and low 0.81 pF capacitance support high-frequency signal integrity in data line protection and RF detector applications.
Thermal resistance of 833 °C/W (junction-to-ambient) and operation from –55 °C to +150 °C allow reliable use in under-hood automotive modules. The device's 100 nA IR at VR = 25 V and TJ = +150 °C confirms stable leakage performance across extended temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports 24 V automotive bus transient suppression without breakdown |
| IF (per diode) | 155 mA - sufficient for logic-level signal routing and low-power analog switching |
| trr | 4.0 ns - enables clean switching up to ~100 MHz digital signal paths |
| CT | 0.81 pF @ 0 V - minimizes capacitive loading on high-speed data lines (e.g., USB, CAN) |
| IR @ 75 V, 25 °C | 2.0 µA - ensures low standby power loss in always-on monitoring circuits |
| PD | 150 mW - defines maximum dissipation under FR-4 pad layout per Diodes' recommended footprint |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first switching path; connects to signal source or pull-up |
| Pin 2 | Cathode (common) | Shared return path for both diodes; ties to ground or reference rail |
| Pin 3 | Anode of Diode 2 | Input node for second independent switching path; enables dual-channel routing |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 |
| Ultra-fast trr = 4.0 ns | Reduces switching loss and prevents signal distortion in >50 MHz clock/data lines |

Applications
| Automotive LIN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting LIN transceiver pins against load-dump transients and ESD events in body control modules. IC Role / Device Role: Dual-clamp diode providing bidirectional voltage limiting to ±15 V while preserving signal rise/fall times. Use Value: 4.0 ns trr avoids pulse distortion during 19.2 kbps LIN signaling; AEC-Q101 qualification ensures field reliability. |

Use Scenario: Demodulating low-amplitude RF signals (e.g., 868 MHz ISM band) in wireless sensor nodes. IC Role / Device Role: High-speed envelope detector using forward conduction of one diode element. Use Value: Fast trr and low CT enable accurate detection of narrow RF pulses without droop or ringing. |
Use Scenario: Level-shifting and fault isolation between 3.3 V microcontroller GPIOs and 24 V industrial sensors. IC Role / Device Role: Dual-path signal steering diode routing inputs to ADC or comparator inputs. Use Value: 85 V VRRM withstands inductive kickback; –55 °C to +150 °C rating supports harsh factory environments. |
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 |
|---|---|---|---|
| BAV99-7-F | Same electrical specs but not AEC-Q101 qualified; standard commercial grade | Lacks PPAP capability and automotive change control documentation | Select when automotive qualification is not required and cost sensitivity is higher |
| NSR0230HT1G | Lower VRRM (30 V), faster trr (3.5 ns), smaller SOD-523 package | Not suitable for 24 V bus protection; limited to low-voltage logic interfaces | Prefer for portable electronics where board space and speed outweigh voltage headroom needs |
Compared with BAV99-7-F, the BAV99TQ-13-F adds automotive traceability and process control; versus NSR0230HT1G, it trades 500 mV lower VF for 55 V higher blocking voltage and broader thermal range - critical for under-hood deployment.

FAQ
What is the pin configuration of BAV99TQ-13-F?
BAV99TQ-13-F uses a three-pin SOT523 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This dual-common-cathode arrangement allows independent signal routing through two diodes sharing one cathode terminal, verified in Diodes' DS30260 package outline and marking diagram.
Is BAV99TQ-13-F suitable for 24 V automotive systems?
Yes - its 85 V VRRM, AEC-Q101 qualification, –55 °C to +150 °C operating range, and IATF16949 manufacturing ensure compatibility with 24 V truck and off-highway vehicle systems. It withstands ISO 7637-2 pulse 1 (–150 V) and pulse 3a/b transients when used with appropriate series impedance.
How does BAV99TQ-13-F differ from standard BAV99-7-F?
BAV99TQ-13-F adds AEC-Q101 qualification, PPAP documentation support, and controlled change management for automotive programs. Electrically identical, it shares the same 85 V VRRM, 4.0 ns trr, and SOT523 package but is produced in IATF16949-certified facilities with enhanced traceability and lot-level test data.
What is the maximum junction temperature during continuous operation?
The absolute maximum junction temperature is +150 °C, and derating begins at +25 °C ambient per the current derating curve in DS30260. At 155 mA per diode and 150 mW total power dissipation on FR-4 with recommended pad layout, TJ remains within limit up to +125 °C ambient, assuming RθJA = 833 °C/W.
