Product details
Overview
P6SMAJ30ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power lines and signal interfaces. It features a 30V reverse standoff voltage, 33.3–38.3V breakdown range at 1mA, 48.4V clamping voltage at 12.4A peak pulse current, and D-FLAT package for space-constrained PCB layouts-used in industrial power supplies and automotive body electronics.
For engineers reviewing the P6SMAJ30ADF-13 datasheet, P6SMAJ30ADF-13 pinout, P6SMAJ30ADF-13 application, or P6SMAJ30ADF-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, thermal resistance (57°C/W on optimized pad), peak pulse power derating above +25°C, and RoHS-compliant matte tin terminations for lead-free reflow compatibility.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device triggered by transient overvoltage events exceeding its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1µA at 30V) and repeatable clamping performance across temperature (-55°C to +150°C).
The device responds within picoseconds to 10/1000µs transients, limiting induced voltage to ≤48.4V while absorbing up to 600W non-repetitive surge energy. Thermal design relies on low RθJT (57°C/W) when mounted on a 0.4" × 0.5" 2oz copper pad per JESD51-7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges without failure under defined thermal conditions |
| Reverse Standoff Voltage (VRWM) | 30V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 33.3–38.3V @ 1mA - guaranteed conduction onset window for predictable clamping initiation |
| Clamping Voltage (VC) | 48.4V @ 12.4A - maximum voltage seen by downstream circuit during specified transient |
| Peak Pulse Current (IPP) | 12.4A - peak current handled at rated clamping voltage under 10×1000µs waveform |
| Thermal Resistance (RθJT) | 57°C/W - junction-to-terminal resistance with 0.4" × 0.5" 2oz copper pad, critical for power dissipation layout |
| Operating Temperature | -55°C to +150°C - supports under-hood automotive and industrial ambient environments |
Pinout & Package
Package: D-FLAT - low-profile surface-mount package (2.25–2.95mm width, 3.95–4.60mm length, 0.90–1.10mm height) with cathode band polarity marking and 0.035g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink | Connected to protected line; conducts surge current to ground when VIN > VBR |
| 2 (Anode) | Reference node | Typically tied to system ground; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable VBR tolerance and low leakage (<1µA) across temperature and lifetime |
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity in properly decoupled circuits |
| D-FLAT low-profile package | Reduces board area by >30% vs. SMA while maintaining thermal performance via exposed terminal |
| RoHS & halogen-free compliance | Meets EU Directive 2011/65/EU and Diodes' "Green" standard (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting 24V digital input channels in programmable logic controllers against ESD and inductive switching transients from solenoids or relays. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between input terminal and ground, clamping transients before they reach input buffer ICs. Use Value: Limits voltage to ≤48.4V during 12.4A surges, preserving 3.3V/5V logic-level interface integrity without adding series impedance. | Use Scenario: Safeguarding LIN bus transceivers and microcontroller GPIOs in door module ECUs exposed to load dump and jump-start events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12V supply rail and LIN signal line, activated within <1ns of overvoltage onset. Use Value: Maintains VCC stability below 50V during ISO 7637-2 Pulse 1/2a/5a tests, preventing latch-up in 32-bit MCUs. |
| DC Power Supply Input Stage | Telecom Remote PHY Equipment |
Use Scenario: Front-end surge suppression for 30V-rated DC-DC converters in base station power distribution units. IC Role / Device Role / Timing Role: First-line transient absorber upstream of input filter capacitors and active rectifiers. Use Value: Absorbs 600W pulses without degradation, enabling compliance with GR-1089-CORE Class B telecom surge requirements. | Use Scenario: Protecting RF amplifier bias lines and data lines in cable modem remote PHY nodes deployed in outdoor cabinets. IC Role / Device Role / Timing Role: Low-capacitance (≈100pF) TVS on 5V/12V bias rails and 100BASE-TX differential pairs. Use Value: Clamps fast transients without distorting 1Gbps Ethernet signals due to minimal parasitic capacitance and no series inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-Q | Same 30V VRWM, but SMA package (higher RθJA = 115°C/W); 600W rating confirmed | Larger footprint; less suitable for ultra-dense layouts where D-FLAT's 4.6mm × 2.8mm saves >40% area | Select when existing SMA land patterns are fixed and thermal margin allows higher RθJA |
| 1.5SMC33A | Higher 33V VRWM, DO-214AB package, same 600W rating; clamping at 53.3V vs. 48.4V | Less precise clamping margin for 30V systems; requires verification of protected IC's absolute max rating | Use only if 33V standoff better matches system nominal voltage and clamping headroom permits |
Compared with SMAJ30A-Q and 1.5SMC33A, P6SMAJ30ADF-13 delivers tighter clamping (48.4V), lower thermal resistance (57°C/W), and smallest PCB footprint-making it optimal for space-constrained, thermally demanding 30V rail protection where precise voltage limiting is critical.

FAQ
What is the maximum clamping voltage of P6SMAJ30ADF-13 under standard test conditions?
The maximum clamping voltage (VC) is 48.4V at 12.4A peak pulse current, measured using the 10×1000µs waveform per REA standard. This value is guaranteed across the full operating temperature range (-55°C to +150°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Can P6SMAJ30ADF-13 be used in bidirectional configurations?
No-P6SMAJ30ADF-13 is a unidirectional TVS diode with cathode-anode polarity. It conducts only when the cathode is positive relative to the anode. For AC or bidirectional signal line protection, a dedicated bidirectional part such as P6SMBJ30CA or two series-opposed unidirectional devices would be required.
What is the recommended PCB pad layout for optimal thermal performance?
For minimum RθJT (57°C/W), use a 0.4" × 0.5" (10.2mm × 12.7mm), 2oz copper pad connected directly to the D-FLAT terminals. Avoid thermal relief spokes; ensure solid copper connection to internal ground planes via multiple vias spaced ≤2mm apart under the pad per Diodes' package outline AN-PCB-001.
Does P6SMAJ30ADF-13 meet automotive AEC-Q200 stress testing requirements?
No-P6SMAJ30ADF-13 is not AEC-Q200 qualified. While it operates from -55°C to +150°C and meets RoHS/halogen-free standards, it lacks the extended reliability testing (temperature cycling, humidity bias, mechanical shock) required for automotive qualification. For AEC-Q200 applications, consider Diodes' AEC-Q200-qualified SMBJ30A or SMCJ30A series.
