Product details
Overview
BAT720,215 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOT23 (TO-236AB) surface-mount package. It delivers 40 V reverse voltage rating, 550 mV forward voltage at 500 mA, 100 µA reverse leakage at 35 V, 90 pF capacitance at 0 V, and operates from −55 °C to 125 °C ambient - enabling ultra-high-speed switching and reverse polarity protection in space-constrained DC power rails.
For engineers reviewing the BAT720,215 datasheet, BAT720,215 pinout, BAT720,215 application, or BAT720,215 equivalent, key selection criteria include low VF for efficiency-critical clamping, low Cd for high-frequency line termination, and SOT23 footprint compatibility with automated PCB assembly in portable and industrial power management circuits.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress, improving reliability in repetitive voltage-clamp duty cycles. Its low junction capacitance (60–90 pF) and fast recovery enable operation beyond 100 MHz in RF and digital signal line termination.
The device is optimized for pulsed forward conduction (IF = 500 mA, tp ≤ 300 µs, δ ≤ 0.02) and exhibits temperature-stable reverse leakage - rising only to 10 mA at VR = 35 V and Tj = 100 °C - making it suitable for thermally demanding environments without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - maximum blocking capability before avalanche; sets safe operating margin for 3.3 V/5 V/12 V rail clamping. |
| VF (Forward Voltage) | 550 mV @ 500 mA - enables low-loss rectification and clamping with <0.275 W conduction loss at rated current. |
| IR (Reverse Current) | 100 µA @ 35 V, 25 °C - ensures minimal standby leakage in battery-powered reverse-polarity protection circuits. |
| Cd (Diode Capacitance) | 90 pF @ 0 V, 1 MHz - supports clean signal integrity in USB, HDMI, and LVDS line termination up to ~100 MHz. |
| Rth(j-a) | 500 K/W - thermal resistance on FR4 PCB defines 200 mW max power dissipation at Tamb ≤ 25 °C. |
| Tj (Junction Temp) | 125 °C - maximum allowable junction temperature; permits operation in sealed enclosures or near heat sources. |
Pinout & Package
Encapsulated in a standard SOT23 (TO-236AB) plastic surface-mount package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch and tin-plated terminations compatible with reflow and wave soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Positive terminal for forward conduction; connects to input/source side in clamping or polarity protection. |
| 2 | Not Connected (n.c.) | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 3 | Cathode (K) | Negative terminal; ties to ground or return path; carries full forward current during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge breakdown under ESD or surge stress, extending lifetime in unregulated input interfaces. |
| Low forward voltage (550 mV) | Reduces conduction loss by >30% vs. standard silicon diodes, critical for battery runtime in portable devices. |
| Low capacitance (90 pF) | Minimizes signal distortion in high-speed data lines; enables use as AC-coupled termination without RC roll-off. |
| SOT23 footprint | Supports high-density layout and automated placement; compatible with industry-standard pick-and-place and reflow profiles. |
Applications
| USB Port Protection | LVDS Line Termination |
|---|---|
Use Scenario: Preventing damage from accidental reverse connection of USB cables in host peripherals. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed in series with VBUS line. Use Value: 550 mV VF limits voltage drop to <2% of 5 V supply, preserving downstream regulator headroom. |
Use Scenario: Matching impedance on differential video/data links to reduce reflections and jitter. IC Role / Device Role / Timing Role: Low-capacitance Schottky clamp across LVDS receiver inputs. Use Value: 90 pF capacitance avoids degrading signal rise/fall times above 100 Mbps. |
| DC Power Rail Clamping | Automotive Body Control Module Inputs |
Use Scenario: Suppressing inductive kickback from relay coils or solenoids in 12 V systems. IC Role / Device Role / Timing Role: Fast-recovery flyback clamp diode across inductive load. Use Value: 40 V VR rating provides 3× safety margin over nominal 12 V rail; 500 ns recovery time prevents latch-up. |
Use Scenario: Protecting microcontroller GPIOs from reverse battery connection in BCM sensor inputs. IC Role / Device Role / Timing Role: Series polarity guard on 5 V sensor supply lines. Use Value: 100 µA IR at 25 °C ensures <1 µA total leakage across 10-channel input bank, minimizing quiescent drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Lower VF (360 mV @ 200 mA), smaller 0.55 mm height, but lower VR (30 V) and higher Cd (120 pF). | Better for ultra-low-power 3.3 V logic clamping; unsuitable for 12 V inductive clamp due to VR limit. | Select when VF dominates over VR/Cd trade-offs in sub-5 V battery systems. |
| Vishay VS-2EDH01HM3/85A | Higher IF (1 A), same VR (40 V), but larger SOD-123 package and higher Rth(j-a) (625 K/W). | Preferred for higher-current (>500 mA) clamping where thermal mass matters more than board area. | Choose when continuous forward current exceeds 500 mA or ambient exceeds 60 °C. |
Compared with NSR0230HT1G and VS-2EDH01HM3/85A, BAT720,215 uniquely balances 40 V VR, 550 mV VF, and 90 pF Cd in the smallest SOT23 footprint - making it optimal for mixed-signal boards where space, speed, and 12 V compatibility intersect.

FAQ
Is BAT720,215 suitable for automotive applications?
No - BAT720,215 is explicitly non-automotive qualified per Nexperia's 2023 revision history. It lacks AEC-Q101 qualification, and its thermal and reliability testing does not meet automotive requirements. For automotive use, Nexperia offers the BAT720Q series with Q-grade qualification and extended temperature validation.
What is the maximum continuous forward current for BAT720,215?
The absolute maximum continuous forward current is 500 mA at Tamb ≤ 25 °C on a standard FR4 PCB. Derating is required above 25 °C ambient: current must be reduced linearly to zero at 125 °C, based on the 500 K/W thermal resistance and 200 mW total power dissipation limit.
Can Pin 2 (n.c.) be used as a heatsink pad or grounded?
No - Pin 2 is internally not connected and electrically isolated. Connecting it to ground or any potential introduces risk of mechanical stress fracture, parasitic capacitance, or solder wicking that compromises thermal performance and long-term reliability. It must remain floating and unconnected per Nexperia's package outline and mounting guidelines.
How does BAT720,215 perform at elevated junction temperatures?
At Tj = 100 °C, reverse leakage increases to 10 mA at VR = 35 V - a 100× rise versus 25 °C - while forward voltage drops slightly (~20 mV). This behavior is documented in Figure 2 of the datasheet and confirms stable switching function but requires system-level leakage budgeting in hot environments.
