Product details
Overview
SBR20M150D1Q-13 from Diodes Incorporated is a 20A, 150V Super Barrier Rectifier (SBR®) diode in TO252 (DPAK) package, featuring ultra-low forward voltage (830 mV @ 10A, 25°C), low leakage (0.05 µA @ 150V, 25°C), and AEC-Q101 qualification for automotive-grade surge protection and polarity reversal circuits.
For engineers reviewing the SBR20M150D1Q-13 datasheet, SBR20M150D1Q-13 pinout, SBR20M150D1Q-13 application, or SBR20M150D1Q-13 equivalent, key selection criteria include its 160A non-repetitive surge rating, soft fast switching (24 ns trr), junction-to-case thermal resistance of 1.8°C/W, and ISO7637-2 pulse compliance for 24V automotive systems.
Technical Context
This SBR rectifier employs proprietary MOS-based process technology to achieve Schottky-like forward conduction with significantly improved high-temperature stability and avalanche ruggedness. Its 150V VRRM and 160A IFSM support robust transient handling in DC-DC converters and load-dump scenarios.
The device delivers VF = 710 mV @ 10A, 125°C - enabling lower conduction loss than standard Schottky diodes at elevated temperatures - while maintaining IR ≤ 10 µA @ 150V, 125°C for reliable blocking in battery-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage; defines safe DC blocking capability in 24V automotive power rails. |
| IO | 20 A - Average rectified output current at 25°C ambient; derates to ~12 A at 100°C per Figure 5. |
| VF Max | 900 mV @ 20A, 25°C - Low conduction loss enables reduced heat generation and smaller heatsinks in high-current paths. |
| IR Max | 0.05 µA @ 150V, 25°C - Ultra-low leakage preserves battery standby time and prevents false triggering in protection circuits. |
| tRR | 24 ns - Soft, fast reverse recovery minimizes switching noise and EMI in synchronous rectification and flyback topologies. |
| RθJC | 1.8 °C/W - Enables direct thermal coupling to PCB copper or heatsink; supports >10W continuous dissipation with proper layout. |
| Avalanche Energy | Rated per Figure 7 - Withstands ISO7637-2 Pulse 1 (-600V), Pulse 2a (+112V), and Pulse 3a/b surges without failure. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal configuration with exposed cathode pad for thermal and electrical performance. Molded green compound, UL 94V-0 rated, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Input terminal for forward conduction; connects to source side in blocking or freewheeling configurations. |
| 2 (Cathode) | Cathode connection | Main output terminal; tied to exposed metal tab for low-inductance, low-resistance return path and thermal conduction. |
| 3 (Cathode Tab) | Common cathode / thermal pad | Electrically and thermally connected to Pin 2; must be soldered to large copper pour for optimal RθJC and surge handling. |
Key Features
| Feature | Design Value |
|---|---|
| MOS-based SBR® technology | Enables Schottky-equivalent VF with superior high-temp IR stability and avalanche ruggedness not achievable with planar Schottky structures. |
| Drop-in compatibility with Schottky diodes | Same TO252 footprint and polarity as common 20A Schottkys - allows direct replacement without PCB redesign. |
| ISO7637-2 surge compliance | Validated for Pulse 1 (−600V), Pulse 2a (+112V), Pulse 3a (−300V), and Pulse 3b (+300V) - eliminates need for external TVS in many automotive protection designs. |
| AEC-Q101 qualification | Qualified for automotive under stress conditions including HTGB, HTRB, and temperature cycling - ensures reliability in engine bay and ADAS modules. |
Applications
| Polarity Protection | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Reverse-battery connection protection in 24V commercial vehicle ECUs and infotainment head units. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power input to prevent damage during incorrect jump-start or battery swap. Use Value: Withstands −600V ISO7637-2 Pulse 1 without clamping or degradation, eliminating need for parallel TVS and reducing BOM count by one component. | Use Scenario: Secondary-side rectification in isolated 24V-to-5V/3.3V flyback converters powering microcontrollers and sensors. IC Role / Device Role / Timing Role: Freewheeling diode conducting during transformer reset phase; critical for efficiency and thermal management. Use Value: 710 mV VF @ 125°C reduces conduction loss by ~18% vs. typical Schottky, lowering junction temperature rise and improving converter MTBF. |
| Recirculating Diode in Solenoid Drivers | Blocking Diode in Dual-Battery Systems |
Use Scenario: Flyback energy recirculation in 24V solenoid valves used in transmission control and braking modules. IC Role / Device Role / Timing Role: Provides low-loss path for inductive kickback during PWM turn-off; suppresses voltage spikes and EMI. Use Value: 24 ns tRR and soft recovery minimize voltage overshoot and radiated emissions, easing EMC certification for Tier-1 suppliers. | Use Scenario: Isolation between starter battery and auxiliary (house) battery in RVs and emergency vehicles. IC Role / Device Role / Timing Role: Prevents backfeed and cross-charging while supporting bidirectional load sharing via external controllers. Use Value: 10 µA IR @ 125°C limits standby drain to <1 µA per diode - extends auxiliary battery life by >20% over standard Schottky alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20U150CT | 20A dual common-cathode SBR in TO263; VF = 850 mV @ 10A, 25°C; higher IR (0.1 µA @ 150V, 25°C). | Requires dual-diode topology; better suited for synchronous rectification where two matched devices are needed. | Select when dual-channel operation or shared cathode layout is required; avoid if single-diode footprint and minimal IR are critical. |
| MBR20150CT | 20A Schottky in TO220AB; VF = 820 mV @ 10A, 25°C but IR = 100 µA @ 150V, 25°C; no AEC-Q101 or ISO7637-2 validation. | Limited to non-automotive industrial use; unsuitable for battery-sensitive or surge-prone environments. | Acceptable only for cost-sensitive, non-automotive 24V systems with no surge requirements and relaxed leakage specs. |
Compared with SBRT20U150CT and MBR20150CT, the SBR20M150D1Q-13 offers the lowest high-temperature leakage, verified automotive surge immunity, and smallest footprint among 20A/150V rectifiers - making it the preferred choice for space-constrained, safety-critical automotive power nodes.

FAQ
Is SBR20M150D1Q-13 qualified for automotive use?
Yes. It is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Full qualification test reports cover HTGB, HTRB, temperature cycling, and mechanical shock - confirming suitability for under-hood and ADAS applications up to 175°C junction temperature.
What is the maximum continuous current at 100°C ambient?
Per Figure 5, the derated IO is approximately 12 A at TA = 100°C with 2″×2″ aluminum board (Note 6). With a 50 mm × 50 mm × 23 mm heatsink (Note 7), it supports ≥16 A continuously due to RθJA = 12°C/W and TJ limit of 175°C.
Can this diode replace a standard Schottky in existing TO252 layouts?
Yes. It uses identical TO252 (DPAK) footprint and pinout (anode–cathode–cathode tab), with matching polarity marking. No PCB rework is needed - only verification that thermal pad area meets Diodes' recommended layout (C = 4.572 mm, Y2 = 10.700 mm).
Does it meet ISO7637-2 Pulse 1 without external clamping?
Yes. The device is characterized to survive −600V (Pulse 1), +112V (Pulse 2a), and ±300V (Pulse 3a/3b) transients per ISO7637-2 when mounted on standard automotive PCBs - confirmed by internal surge testing and referenced in the datasheet's "Surge Protection" section.
