Product details
Overview
BAS19,215 from Nexperia is a high-voltage switching diode in SOT23 (TO-236AB) package, rated for 100 V reverse voltage, 200 mA continuous forward current, and 50 ns reverse recovery time. It serves as a fast-switching, low-leakage clamping or polarity protection device in automotive power rails and industrial DC-DC converter feedback paths.
For engineers reviewing the BAS19,215 datasheet, BAS19,215 pinout, BAS19,215 application, or BAS19,215 equivalent, key selection criteria include verified AEC-Q101 qualification, 100 nA reverse leakage at 100 V/25 °C, 5 pF junction capacitance, thermal resistance of 500 K/W (junction-to-ambient), and confirmed anode–cathode–NC pin configuration on SOT23.
Technical Context
The BAS19,215 is a silicon planar epitaxial high-speed switching diode optimized for rapid turn-off under high-voltage transient conditions. Its 50 ns trr and 5 pF Cd enable clean signal edge handling in clamp circuits up to 100 V, while its 100 nA IR at VR = 100 V ensures minimal standby loss in always-on automotive modules.
Designed for operation across −55 °C to +150 °C ambient, it maintains stable VF (1.0–1.25 V at IF = 100–200 mA) and exhibits predictable derating-IF drops linearly to zero at 150 °C on FR4 PCB. The NC pin (Pin 2) eliminates parasitic coupling in high-density layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V maximum continuous reverse voltage - supports clamping in 48 V and 60 V automotive systems without breakdown. |
| trr | 50 ns maximum reverse recovery time - enables reliable switching at >1 MHz in flyback snubbers and PWM gate drivers. |
| IR | 100 nA at VR = 100 V, Tj = 25 °C - ensures <1 µW leakage power in battery-backed circuits. |
| Cd | 5 pF maximum at VR = 0 V, f = 1 MHz - minimizes capacitive loading on high-impedance control nodes. |
| IF | 200 mA continuous forward current - sufficient for driving small relays, LED indicators, or optocoupler inputs. |
| Rth(j-a) | 500 K/W on FR4 PCB - requires no heatsink for ≤100 mW dissipation in typical ambient conditions. |
| AEC-Q101 | Qualified per stress test standard for discrete semiconductors - validated for under-hood automotive use. |
Pinout & Package
Package: TO-236AB (SOT23), 3-lead surface-mount plastic package with standard footprint (2.9 mm × 1.3 mm × 1.1 mm height), JEDEC-compliant outline, and FR4-compatible reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to positive rail or switch node in clamp configurations. |
| 2 | Not Connected (n.c.) | Internally unconnected; electrically isolated - allows routing underneath without short risk. |
| 3 | Cathode (K) | Forward current exit; ties to ground, reference node, or controller input in reverse-polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 50 ns ensures minimal switching loss and overshoot in 1–5 MHz DC-DC feedback loops. |
| Low leakage | IR ≤ 100 nA at 100 V/25 °C preserves battery life in always-on vehicle modules like CAN wake-up receivers. |
| Small SMD package | SOT23 footprint saves >60% board area vs. DO-35, enabling compact ECU designs with tight layout constraints. |
| AEC-Q101 qualified | Validated for temperature cycling, HTRB, and ESD per automotive stress requirements - no additional qualification needed. |
Applications
| Automotive Power Rail Clamping | Industrial DC-DC Feedback Protection |
|---|---|
Use Scenario: Suppressing load-dump transients on 12 V/24 V vehicle battery lines. IC Role / Device Role / Timing Role: Fast-clamp diode placed between supply rail and ground to shunt >100 V spikes within 50 ns. Use Value: Prevents overvoltage damage to MCU power supplies and CAN transceivers without adding TVS cost or capacitance. |
Use Scenario: Protecting optocoupler input in isolated flyback converter feedback path. IC Role / Device Role / Timing Role: Reverse-polarity blocking diode ensuring correct bias direction during startup and fault events. Use Value: Eliminates risk of feedback loop inversion due to accidental reverse connection, preserving regulation stability. |
| High-Speed Signal Level Shifting | Reverse Polarity Input Protection |
Use Scenario: Level-shifting logic signals between 3.3 V microcontrollers and 5–12 V sensor interfaces. IC Role / Device Role / Timing Role: Passive clamping diode limiting signal swing to safe thresholds without active circuitry. Use Value: Achieves sub-10 ns response with <5 pF loading - avoids timing skew in UART/SPI clock domains. |
Use Scenario: Guarding USB-C or barrel-jack inputs against incorrect adapter insertion. IC Role / Device Role / Timing Role: Series-connected anode-to-input diode blocking reverse current flow during miswiring. Use Value: Limits fault current to <200 mA while maintaining <1.25 V forward drop - protects downstream LDOs and USB controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBD1203LT1G | Same SOT23 package, VR = 100 V, but trr = 75 ns and IR = 500 nA - slower and leakier. | Less suitable for >500 kHz switching; higher leakage may affect battery-critical sleep modes. | Select only if cost sensitivity outweighs speed/leakage requirements and AEC-Q101 is not mandatory. |
| Vishay 1N4148WS | VR = 100 V, trr = 4 ns (faster), but IR = 25 nA (lower leakage), and not AEC-Q101 qualified. | Acceptable for commercial-grade high-speed logic clamping, but lacks automotive reliability validation. | Prefer for non-automotive consumer or industrial designs where ultra-fast trr is prioritized over qualification. |
Compared with MMBD1203LT1G and 1N4148WS, the BAS19,215 uniquely balances AEC-Q101 compliance, 50 ns trr, and 100 nA IR in SOT23 - making it the only option qualified for automotive under-hood clamping where both speed and leakage matter.

FAQ
Is BAS19,215 pin-compatible with BAS21 or BAS20?
No. BAS19,215 has Pin 2 marked as "n.c." (not connected), whereas BAS20 and BAS21 feature functional Pin 2 (cathode or anode depending on variant). Substituting them risks open-circuit failure or unintended shorts. Always verify pin mapping using the official Nexperia pinning diagrams before replacement.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature is 150 °C under all conditions. For repetitive pulse operation, thermal limits are governed by Rth(j-a) = 500 K/W and duty cycle - e.g., at 10% duty cycle and 1 A peak, average power must stay below 250 mW to avoid exceeding Tj(max).
Does the "JP%" marking code indicate RoHS compliance?
Yes. All BAS19,215 units marked "JP%" (where % is a site code) are manufactured per Nexperia's RoHS-compliant process and meet EU Directive 2011/65/EU, including exemption 7a for lead in high-melting-temperature solder alloys used in internal die attachment.
Can BAS19,215 be used in place of a Zener diode for voltage clamping?
No. BAS19,215 is a switching diode, not a Zener. It conducts only in forward bias and blocks up to 100 V in reverse - it does not regulate or clamp at a defined reverse breakdown voltage. Use dedicated Zeners (e.g., BZX55C10) or TVS diodes for precision voltage clamping.
