Product details
Overview
BAS16VAQ-7 from Diodes Incorporated is a triple isolated fast-switching diode array in SOT563 package, rated for 100V peak reverse voltage, 200mA forward current, and 4ns reverse recovery time. It delivers low forward voltage (0.715V @ 1mA), low capacitance (1.5pF), and AEC-Q101 qualification for automotive signal routing and ESD protection circuits.
For engineers reviewing the BAS16VAQ-7 datasheet, BAS16VAQ-7 pinout, BAS16VAQ-7 application, or BAS16VAQ-7 equivalent, key selection criteria include reverse recovery speed, junction-to-ambient thermal resistance (357°C/W), triple-diode isolation integrity, and IATF 16949-certified manufacturing traceability.
Technical Context
The BAS16VAQ-7 integrates three independent silicon switching diodes on a single thermally efficient copper alloy leadframe, enabling compact multi-rail clamping or signal steering without cross-talk. Its 1.5pF capacitance at 0V bias and 4ns trr support high-frequency signal integrity in 10–100MHz digital interfaces.
Designed for automotive-grade reliability, it operates across –55°C to +150°C with <0.5μA leakage at 80V reverse bias (25°C) and maintains <30nA leakage at 25V/150°C - critical for low-power sensor interface and CAN bus protection nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 100 V - supports 24V automotive supply rail transients and ISO 7637-2 pulse clamping |
| Forward Voltage | 0.715 V @ 1 mA - minimizes voltage drop in low-current logic-level signal conditioning paths |
| Reverse Recovery Time | 4 ns - enables clean switching in >25MHz clock distribution and data line steering |
| Total Capacitance | 1.5 pF @ 0 V - preserves signal edge fidelity in USB 2.0 and LIN bus termination networks |
| Thermal Resistance | 357 °C/W - requires minimal PCB copper area (2 oz FR-4 pad) for 350 mW power dissipation |
| Leakage Current | 0.5 μA @ 80 V, 25°C - ensures stable biasing in high-impedance analog sensor front-ends |

IC Role / Device Role / Timing Role: Two diodes configured as low-capacitance bidirectional TVS clamps; third diode routes VBUS overvoltage to chassis ground. Use Value: 1.5pF CT preserves 480 Mbps eye diagram integrity; 0.715V VF ensures minimal insertion loss in high-speed differential signaling. |
| Multi-Rail Power Sequencing | Low-Power Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single N-channel MOSFET (30V, 2.6A), not functionally equivalent - lacks diode functionality and triple isolation | Not suitable for clamping or signal steering; intended for load switching only | Select only if replacing discrete MOSFETs, not diode arrays |
| BAS21DW-7-F | Dual diode array (SOT363), 200V VR, 300mA IF, 50ns trr - slower, higher capacitance (4pF), dual vs. triple configuration | Limited to two-rail protection; insufficient for three-rail systems like LIN + VBAT + Wake-up line | Acceptable only when third diode is omitted or implemented externally |
Compared with BAS16VAQ-7, BAS21DW-7-F offers higher voltage rating but sacrifices speed, capacitance performance, and channel count; DMN3026LSD-13 is not a functional alternative due to fundamental device type mismatch.

FAQ
Is BAS16VAQ-7 pin-compatible with BAS16W-7?
No. BAS16VAQ-7 uses SOT563 (6-pin) with triple isolated diodes, while BAS16W-7 uses SOT323 (3-pin) with single diode. Pin count, terminal assignment, and internal topology differ fundamentally - direct replacement is not possible without PCB redesign.
What is the maximum operating temperature for continuous use?
The BAS16VAQ-7 is rated for continuous operation from –55°C to +150°C junction temperature. At 150°C, leakage rises to 30nA at 25V reverse bias, and power derating reduces usable dissipation to ~125mW based on the published derating curve (Fig. 1).
Does BAS16VAQ-7 meet IEC 61000-4-2 Level 4 ESD requirements?
Yes - its 4ns trr, 1.5pF capacitance, and low leakage enable effective clamping of ±8kV contact discharges when properly laid out with short traces and grounded thermal pads. Diodes' application note AP02011 confirms validated layout practices for IEC 61000-4-2 compliance.
Can BAS16VAQ-7 be used in place of a single discrete diode?
Yes - any one of its three isolated diodes can be used independently (e.g., Pins 1–2 only), with identical electrical specs to the full array. Remaining pins must be left unconnected or tied to appropriate potentials per circuit requirements; no internal coupling exists between elements.
