Product details
Overview
P6SMAJ60ADF-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 reverse standoff voltage of 60.0 V, breakdown voltage range of 66.7–76.7 V at 1.0 mA test current, clamping voltage of 96.8 V at 6.2 A peak pulse current, and fast response time under 1.0 ns. It is used in industrial power supplies to protect downstream regulators and microcontrollers from ESD and lightning-induced surges.
For engineers reviewing the P6SMAJ60ADF-13 datasheet, P6SMAJ60ADF-13 pinout, P6SMAJ60ADF-13 application, or P6SMAJ60ADF-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under IEC 61000-4-5 surge conditions, thermal resistance on standard FR-4 layouts, and D-FLAT package compatibility with high-density PCB routing.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below VRWM (60.0 V) and rapidly transitions to low-impedance conduction above VBR (min 66.7 V), limiting transient energy to safe levels. Its glass-passivated die construction ensures stable leakage performance and long-term reliability under repeated surge stress.
The device uses a single-junction PN structure optimized for low capacitance (typ. <100 pF at VRWM) and fast turn-on-critical for protecting high-speed communication lines and switching power supply feedback paths without signal distortion or regulation instability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains 10/1000 µs waveform surges up to this level without failure, meeting IEC 61000-4-5 Level 4 requirements. |
| Reverse Standoff Voltage | 60.0 V - Maximum continuous DC or RMS voltage applied without significant leakage; sets operating margin before clamping begins. |
| Clamping Voltage | 96.8 V @ 6.2 A - Voltage across terminals during peak surge; must remain below absolute maximum rating of protected ICs. |
| Breakdown Voltage Range | 66.7–76.7 V @ 1.0 mA - Confirmed avalanche onset window; ensures predictable turn-on behavior across temperature and unit variation. |
| Thermal Resistance (J-A) | 92 °C/W - Measured on 0.4" × 0.5" 2 oz copper pad; determines junction temperature rise under sustained power dissipation. |
| Leakage Current | ≤1.0 µA @ 60.0 V - Minimal standby loss in battery-powered systems; avoids unnecessary drain in always-on circuits. |
Pinout & Package
Package: D-FLAT (low-profile surface-mount package with 2-terminal configuration, UL 94V-0 rated molded plastic case, cathode band polarity indicator).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side connection point for unidirectional clamping path | Connected to protected line; conducts surge current toward ground when voltage exceeds VBR. |
| 2 (Anode) | Reference/ground return terminal | Typically tied to system ground plane; completes clamping loop and defines reference for VRWM and VC measurements. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Eliminates moisture sensitivity and interfacial degradation, enabling >10-year field life in humid industrial environments. |
| D-FLAT package footprint | 2.25–2.95 mm × 3.95–4.60 mm outline with 0.50–1.30 mm lead length-supports automated placement and reflow while minimizing board area use. |
| Lead-free & halogen-free | Meets RoHS 2 (2011/65/EU) and JEDEC J-STD-020 Level 1 moisture sensitivity; compatible with lead-free assembly processes. |
| Fast response time | <1.0 ns turn-on delay ensures clamping initiates before most IC input structures experience damage from ESD or fast transients. |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module (BCM) Power Input |

| Telecom Power Feeds (PoE) | Medical Diagnostic Equipment Power Rails |
|
Use Scenario: Secondary surge suppression on 48 V DC power feed lines in IEEE 802.3af/at PoE injectors and splitters. IC Role / Device Role / Timing Role: Fast-reacting clamp parallel to DC-DC converter input, limiting transients before they reach isolation barriers. Use Value: 92 °C/W RθJA enables reliable operation on compact PCBs with limited copper area, supporting continuous 48 V operation. |
Use Scenario: Protecting isolated 5 V and 3.3 V rails powering analog front-end ADCs and sensor interfaces in portable ultrasound devices. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) TVS placed adjacent to LDO inputs to prevent ESD-induced latch-up without affecting signal integrity. Use Value: 60.0 V VRWM provides ample margin above 3.3/5 V rails while maintaining sub-µA leakage critical for low-noise analog stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-Q | Same 60 V VRWM and 96.8 V VC, but AEC-Q200 qualified and rated for automotive temperature range (−55°C to +175°C junction). | Required for under-hood automotive ECUs; not necessary for industrial or telecom where ambient stays <+85°C. | Select SMAJ60A-Q only if AEC-Q200 compliance and extended TJ range are mandated by system-level qualification. |
| 1.5SMC60A | Higher 1500 W peak power rating, larger SMC package (7.11 × 6.22 mm), and higher clamping voltage (100 V @ 15 A). | Suitable for higher-energy surge environments (e.g., AC mains input); incompatible with space-constrained D-FLAT layouts. | Choose 1.5SMC60A only when surge energy exceeds 600 W capability and PCB layout allows larger footprint. |
Compared with SMAJ60A-Q and 1.5SMC60A, P6SMAJ60ADF-13 delivers optimal balance of compact D-FLAT packaging, 600 W surge handling, and industrial-grade reliability-making it ideal for space-limited, cost-sensitive designs where automotive qualification or extreme power rating are unnecessary.

FAQ
What is the maximum operating temperature for P6SMAJ60ADF-13?
The device supports an operating junction temperature range of −55°C to +150°C. Its thermal resistance (RθJA) is 92 °C/W when mounted on a 0.4" × 0.5" 2 oz copper pad, allowing reliable operation at ambient temperatures up to +85°C with appropriate derating per Figure 1 in DS38930 Rev. 2–2.
Does P6SMAJ60ADF-13 meet IEC 61000-4-2 and IEC 61000-4-5 standards?
P6SMAJ60ADF-13 is characterized for 600 W peak pulse power using the 10/1000 µs waveform defined in IEC 61000-4-5, and its <1.0 ns response time and low leakage make it suitable for IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) protection circuits-though system-level validation is required for full compliance.
Can P6SMAJ60ADF-13 be used in bidirectional configurations?
No. P6SMAJ60ADF-13 is a unidirectional TVS diode with cathode/anode polarity marked on the D-FLAT package. For bidirectional protection, Diodes Incorporated offers the P6SMBJ60CA series, which uses a symmetrical dual-junction structure and identical 60 V standoff rating.
What is the typical total capacitance of P6SMAJ60ADF-13 at 0 V bias?
Typical total capacitance is <100 pF at VRWM = 60 V and f = 1 MHz, as shown in Figure 2 of DS38930 Rev. 2–2. At 0 V bias, capacitance is higher (~150–200 pF), but the device remains suitable for DC and low-frequency signal line protection where bandwidth is not critical.
