Product details
Overview
BAV3004WQ-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount high-voltage, low-leakage switching diode in SOD-123 package, featuring 350 V peak repetitive reverse voltage (VRRM), ≤100 nA leakage at 240 V/150°C, and 50 ns reverse recovery time (trr). It serves as a fast, reliable clamping and protection diode in automotive power supply rails and battery management circuits.
For engineers reviewing the BAV3004WQ-7-F datasheet, BAV3004WQ-7-F pinout, BAV3004WQ-7-F application, or BAV3004WQ-7-F equivalent, this part supports high-reliability automotive designs requiring stable reverse blocking, low thermal drift leakage, and IATF 16949-certified traceable sourcing.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for high-voltage blocking and fast minority-carrier recombination. Its 350 V VRRM rating enables use in 24 V and 48 V automotive systems with margin against transients, while the 50 ns trr ensures minimal switching loss in flyback and clamp topologies.
The device operates across –65°C to +150°C with 312°C/W junction-to-ambient thermal resistance (RθJA) under standard PCB mounting, and maintains ≤100 nA IR at VR = 240 V and TJ = 150°C - critical for low-power sleep-mode integrity in ADAS sensors and body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 350 V - Withstands repetitive 350 V reverse transients without breakdown; suitable for 24 V/48 V automotive bus clamping. |
| trr | 50 ns max - Enables efficient high-frequency switching in snubber and freewheeling paths up to ~10 MHz. |
| IF | 225 mA continuous - Supports sustained current in signal-level protection and bias networks without derating at 25°C. |
| IR @ 240 V / 150°C | ≤100 nA - Ensures negligible standby current drain in always-on vehicle modules (e.g., CAN wake-up receivers). |
| PD | 400 mW - Delivers usable power handling on standard 1 oz copper FR-4 with minimal heatsinking. |
| RθJA | 312 °C/W - Reflects thermal performance on JEDEC-standard 2-layer test board; requires layout-aware thermal relief for >100°C ambient. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TCT, and ESD per AEC specification; PPAP-capable. |
Pinout & Package
Package: SOD-123 - Surface-mount plastic case (UL 94V-0), 0.01 g weight, cathode band polarity marking, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., ground or return path) during conduction; must be routed with low-inductance trace in high-dI/dt applications. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., battery or supply); cathode band identifies this terminal visually and in automated optical inspection (AOI). |
Key Features
| Feature | Design Value |
|---|---|
| Low leakage at high temperature | ≤100 nA at VR = 240 V and TJ = 150°C - preserves battery life in always-on automotive ECUs without active leakage compensation. |
| Fast reverse recovery | 50 ns max - reduces switching loss and EMI in high-frequency clamp circuits used in DC-DC converters and motor drivers. |
| AEC-Q101 qualification | Validated for automotive use with full PPAP support - eliminates qualification overhead for Tier 1 suppliers integrating into safety-critical systems. |
| Green construction | Halogen- and antimony-free, RoHS 3 compliant (<900 ppm Br/Cl, <1000 ppm Sb) - meets global environmental compliance mandates without performance trade-offs. |
Applications
| Automotive Body Control Module (BCM) | 48 V Mild Hybrid DC-DC Converter |
|---|---|
Use Scenario: Reverse polarity and load dump protection in BCM power input stage. IC Role / Device Role / Timing Role: High-voltage clamping diode placed across input filter capacitor to absorb ISO 7637-2 pulse 5a/b transients. Use Value: 350 V VRRM provides 40 V margin above 48 V system nominal, while ≤100 nA leakage avoids parasitic drain on backup battery during vehicle sleep mode. |
Use Scenario: Freewheeling path in synchronous buck converter output stage. IC Role / Device Role / Timing Role: Fast-recovery diode conducting during high-side FET off-time to maintain current continuity. Use Value: 50 ns trr minimizes reverse recovery charge (Qrr) and associated switching loss, improving efficiency at 300–500 kHz switching frequencies. |
| ADAS Camera Power Supply | Electric Power Steering (EPS) Sensor Interface |
Use Scenario: Overvoltage clamp for image sensor bias rail in rear-view camera module. IC Role / Device Role / Timing Role: Transient voltage suppression diode protecting 3.3 V LDO input from ESD and inductive kickback. Use Value: Low 1.03 V VF at 200 mA ensures minimal voltage drop across protection path, preserving headroom for downstream analog circuitry. |
Use Scenario: Signal line protection for Hall-effect position sensor in EPS motor assembly. IC Role / Device Role / Timing Role: Bidirectional ESD clamp on differential analog signal pair (e.g., SENT or PWM feedback lines). Use Value: 1.0 pF typical capacitance at 0 V bias prevents signal integrity degradation on sub-MHz sensor outputs while meeting ISO 10605 Class 3A ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04SW | Higher IF(RMS) = 1 A, but VRRM = 400 V and trr = 35 ns; larger SOD-128 package; 200 nA IR at 240 V/150°C. | Better surge handling and faster recovery, but higher leakage compromises ultra-low-power sleep modes. | Select when transient energy absorption (e.g., ISO 16750-2 pulse 4) dominates over standby current budget. |
| ON Semiconductor MMBD3004LT1G | Same SOD-123 footprint, VRRM = 350 V, but trr = 75 ns and IR = 200 nA at 240 V/150°C; not AEC-Q101 qualified. | Lacks automotive qualification and has higher leakage - unsuitable for ASIL-B/C systems or extended-temperature deployments. | Acceptable only for non-automotive industrial or consumer applications where qualification and leakage are non-critical. |
Compared with STTH1R04SW and MMBD3004LT1G, the BAV3004WQ-7-F uniquely balances AEC-Q101 compliance, 100 nA high-temp leakage, and 50 ns recovery in the compact SOD-123 package - making it optimal for space-constrained, thermally demanding automotive modules requiring both reliability and low quiescent drain.

FAQ
What is the maximum operating temperature for BAV3004WQ-7-F?
The BAV3004WQ-7-F is rated for junction and storage temperatures from –65°C to +150°C. Its leakage current remains within specification (≤100 nA) at 150°C under 240 V reverse bias, enabling deployment in engine bay and transmission control units where ambient temperatures exceed 105°C.
Is BAV3004WQ-7-F compatible with lead-free reflow soldering processes?
Yes - the device features matte tin-plated terminals over Alloy 42 leadframe and is qualified for standard Pb-free reflow profiles (J-STD-020, peak 260°C). Its SOD-123 package is moisture sensitivity level 1, eliminating bake requirements prior to assembly.
Does BAV3004WQ-7-F require external heat sinking in typical automotive applications?
No - with a thermal resistance of 312°C/W (junction-to-ambient) on standard 2-layer FR-4, the diode dissipates up to 400 mW without added heatsinking. At 225 mA forward current and 0.87 V typical VF, power dissipation is ~196 mW, keeping junction temperature well within limits even at 105°C ambient.
How does the AEC-Q101 qualification impact supply chain assurance for BAV3004WQ-7-F?
AEC-Q101 qualification confirms that each production lot undergoes accelerated stress testing (HTOL, TCT, ESD) per automotive standards. Combined with IATF 16949 certification and PPAP capability, this enables Aetrix to provide full lot traceability, change notification, and long-term supply commitments aligned with OEM program lifecycles.
