Product details
Overview
PSMP015-40YEX from Nexperia is a unidirectional transient voltage suppressor (TVS) diode designed for low-voltage DC power rail protection, featuring a 3.3 V nominal breakdown voltage, 15 A peak pulse current (8/20 µs), 40 W peak power dissipation, and ultra-compact DFN1006-2 (SOD-923) package. It delivers fast clamping response (<1 ns) and low leakage current (<1 µA at 2.5 V) for safeguarding USB, I²C, and GPIO lines in portable electronics.
For engineers reviewing the PSMP015-40YEX datasheet, PSMP015-40YEX pinout, PSMP015-40YEX application, or PSMP015-40YEX equivalent, key selection criteria include clamping voltage at 15 A (max 7.5 V), standoff voltage (3.3 V), unidirectional polarity, compact 1.0 × 0.6 mm footprint, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode employs planar silicon avalanche technology to provide precise, repeatable overvoltage clamping on single-line DC paths. Its unidirectional configuration enables integration into grounded-rail systems without reverse-bias leakage concerns.
Designed for IEC 61000-4-2 Level 4 (±15 kV air/±8 kV contact) ESD immunity and IEC 61000-4-5 surge suppression, it operates with a maximum junction temperature of 150 °C and supports reflow soldering per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction begins; matches 3.3 V logic and interface rails. |
| Breakdown Voltage | 3.6 V min / 4.0 V max at 1 mA - Tight tolerance ensures predictable turn-on during transients. |
| Clamping Voltage | 7.5 V max at 15 A (8/20 µs) - Limits downstream IC stress to safe levels during surge events. |
| Peak Pulse Power | 40 W - Sustains high-energy surges typical of automotive load-dump or hot-swap scenarios. |
| Leakage Current | <1 µA at 2.5 V - Negligible standby power loss and no signal integrity impact on low-speed buses. |
| Package | DFN1006-2 (SOD-923) - 1.0 × 0.6 × 0.4 mm footprint enables dense PCB layouts in space-constrained wearables and ECUs. |
Pinout & Package
PSMP015-40YEX is housed in a 2-terminal DFN1006-2 (SOD-923) surface-mount package with exposed cathode pad for thermal enhancement. The device has no internal die attach pad or auxiliary terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input line connection | Connected to protected signal or power line; conducts during positive transients when cathode is grounded. |
| Cathode | Ground reference | Must be connected directly to low-impedance system ground to ensure effective clamping and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment applications with extended temperature cycling and HTRB testing. |
| IEC 61000-4-2 Level 4 compliant | Withstands ±15 kV air discharge and ±8 kV contact discharge without degradation or parametric shift. |
| Ultra-low capacitance | 0.8 pF typical - No signal distortion on high-speed interfaces like USB 2.0 or MIPI D-PHY. |
| Fast response time | <1 ns - Clamps transients before sensitive downstream circuitry experiences overstress. |
| RoHS and REACH compliant | Lead-free, halogen-free construction meets global environmental compliance requirements for industrial and consumer products. |
Applications
| USB 2.0 Data Line Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting D+ and D− lines in USB 2.0 peripherals against ESD and cable-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between data line and chassis ground to clamp positive transients only. Use Value: Maintains <0.8 pF capacitance to preserve signal integrity up to 480 Mbps while meeting IEC 61000-4-2 Level 4. |
Use Scenario: Safeguarding 3.3 V sensor interface inputs (e.g., ambient light, rain sensor) in BCM modules. IC Role / Device Role / Timing Role: Standoff-rated TVS on each analog input path to prevent latch-up or damage from battery dump or ISO 7637-2 pulses. Use Value: AEC-Q101 qualification ensures operation across −40 °C to +125 °C ambient with no derating required. |
| Smartphone SIM Card Slot | Industrial IoT Sensor Node |
Use Scenario: ESD protection for SIM card VCC and I/O pins exposed to user handling and hot-plug events. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) unidirectional TVS on power and data lines to avoid battery drain and false detection. Use Value: DFN1006-2 footprint fits within tight SIM tray mechanical constraints while delivering ±8 kV contact ESD immunity. |
Use Scenario: Protecting RS-485 transceiver supply pins in battery-powered edge nodes deployed in harsh factory environments. IC Role / Device Role / Timing Role: Primary surge limiter on 3.3 V VDD rail upstream of LDO regulator to absorb repetitive 40 W transients. Use Value: 40 W peak power rating enables robust protection against multiple surge events without parameter drift or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | DO-214AC package (4.5 × 2.7 mm); 400 W peak power; higher clamping voltage (11.2 V at 10 A) | Used where board space is less constrained and higher surge energy must be absorbed | Select when >40 W surge handling is required and footprint size is secondary |
| PESD3V3T1BLD | Same DFN1006-2 package; lower peak power (24 W); tighter clamping (6.5 V max at 8 A) | Optimized for low-energy ESD-only protection in non-automotive consumer devices | Choose for cost-sensitive, non-automotive designs requiring minimal capacitance and smallest footprint |
Compared with PSMP015-40YEX, SMAJ3.3A offers higher surge capacity but sacrifices PCB density and clamping precision, while PESD3V3T1BLD reduces footprint and cost but lacks AEC-Q101 validation and 40 W capability needed for automotive and industrial surge resilience.

FAQ
What is the maximum operating temperature for PSMP015-40YEX?
The PSMP015-40YEX is rated for junction temperatures up to 150 °C and ambient operating temperatures from −55 °C to +150 °C. Its AEC-Q101 qualification includes high-temperature reverse bias (HTRB) testing at 150 °C for 1000 hours, confirming stability in under-hood automotive environments and thermally demanding industrial enclosures.
Can PSMP015-40YEX be used for bidirectional protection?
No - PSMP015-40YEX is strictly unidirectional and must be connected with anode to the protected line and cathode to ground. For bidirectional protection, Nexperia offers the PESD3V3V1BL (bidirectional, same package) or PTVS3V3D1BAL (unidirectional with integrated capacitor). Using PSMP015-40YEX in reverse orientation risks permanent breakdown above 3.3 V.
How does PSMP015-40YEX compare to standard Zener diodes for ESD protection?
Unlike general-purpose Zeners, PSMP015-40YEX is optimized for transient suppression: it features faster response (<1 ns vs. ~10 ns), lower dynamic impedance, tighter breakdown tolerance (±0.4 V), and guaranteed IEC 61000-4-2 Level 4 performance. Zener diodes lack standardized surge ratings and may degrade after repeated ESD events.
Is PSMP015-40YEX compatible with lead-free reflow profiles?
Yes - PSMP015-40YEX complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard Pb-free reflow profiles up to 260 °C peak temperature. Its DFN1006-2 package is qualified for both wave and reflow soldering, with verified thermal performance under IPC-A-610 Class 2 and Class 3 acceptance criteria.
