Product details
Overview
PTVS60VS1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 60 V, VBR(min) = 66.7 V, VCL = 96.8 V at IPPM = 4.1 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS60VS1UTR-Q datasheet, PTVS60VS1UTR-Q pinout, PTVS60VS1UTR-Q application, or PTVS60VS1UTR-Q equivalent, key selection criteria include clamping voltage under peak pulse current, junction temperature derating behavior, AEC-Q101 qualification status, and SOD123W thermal resistance to solder point (Rth(j-sp) = 18 K/W).
Technical Context
This TVS diode uses a planar silicon junction structure optimized for stable breakdown behavior across -55 °C to +185 °C ambient. Its unidirectional configuration provides low clamping voltage during reverse-biased transients while maintaining <0.001 µA IRM at VRWM.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2. Thermal design relies on direct cathode tab conduction to PCB, enabling Rth(j-sp) = 18 K/W with proper solder pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 66.7 V - Breakdown voltage at 1 mA test current; defines onset of avalanche conduction |
| VCL | 96.8 V - Clamped voltage at IPPM = 4.1 A (10/1000 µs); limits downstream IC stress |
| PPPM | 400 W - Peak pulse power handling capability; determines surge survivability |
| Tj max | 185 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point; guides PCB copper area design |
| IRM | 0.001 µA - Reverse leakage at VRWM; ensures minimal standby power loss |
Pinout & Package
PTVS60VS1UTR-Q is housed in a SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads and 1 mm profile height. The cathode is marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); absorbs positive transients when reverse-biased |
| 2 (A) | Anode | Connected to ground reference; completes current path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and ESD stress tests |
| High-temperature operation | Rated for continuous operation at Tamb = 185 °C and Tj = 185 °C without derating |
| Low-profile SMD package | SOD123W footprint enables dense PCB layouts while maintaining 1 mm height for mechanical clearance |
| 30 kV ESD robustness | Withstands contact and air discharge per IEC 61000-4-2-reduces need for external ESD protection |
| Stable clamping performance | VCL variation ≤ ±5 % over -55 °C to +150 °C ensures consistent protection across vehicle operating range |
Applications

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 | Lower PPPM (400 W same), but VRWM = 60 V, VCL = 96.8 V, Tj max = 150 °C, not AEC-Q101 qualified | Limited to non-automotive industrial use due to lower temperature rating and lack of automotive qualification | Select when cost sensitivity outweighs AEC-Q101 requirement and ambient stays below 150 °C |
| SMCJ60A-Q | Same VRWM/VCL, but larger SMC package (7.1 mm × 6.2 mm × 2.6 mm), PPPM = 1500 W, AEC-Q101 qualified | Higher surge capacity suits infrequent high-energy events (e.g., alternator load dump), but requires 3× PCB area | Choose when system-level surge testing exceeds 400 W and board space permits larger footprint |
Compared with SMAJ60A, PTVS60VS1UTR-Q delivers identical clamping performance with AEC-Q101 validation and 185 °C operation-critical for under-hood deployment. Against SMCJ60A-Q, it trades peak power headroom for 70 % smaller footprint and lower thermal mass, optimizing for space-constrained automotive modules.

FAQ
What is the maximum clamping voltage of PTVS60VS1UTR-Q at its rated peak pulse current?
The clamping voltage (VCL) is 96.8 V at IPPM = 4.1 A under the standard 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and remains stable within ±5 % across the full operating temperature range from −55 °C to +150 °C, ensuring predictable protection margin for downstream components.
Does PTVS60VS1UTR-Q require derating above 25 °C ambient temperature?
No derating is required for junction temperature up to 185 °C, as confirmed by Figure 2 in the datasheet showing PPPM remains at 100 % of rated 400 W up to Tj = 150 °C and retains >80 % capability at Tj = 185 °C. PCB layout must maintain Rth(j-sp) ≤ 18 K/W via adequate cathode pad copper area to realize this performance.
How is polarity identified on the PTVS60VS1UTR-Q package?
Polarity is indicated by a marking bar on the top surface of the SOD123W package, aligned with Pin 1 (cathode). This matches the simplified outline in Table 2 and Figure 5, where the cathode terminal connects to the marked side and serves as the transient current return path to ground during clamping events.
Is PTVS60VS1UTR-Q compatible with lead-free reflow soldering processes?
Yes-it is qualified for standard lead-free reflow per JEDEC J-STD-020, with a peak temperature rating of 260 °C. The recommended reflow footprint (Figure 6) specifies a 0.1 mm stencil thickness and 1.2 mm × 1.4 mm solder land dimensions for the cathode pad to ensure reliable thermal conduction and mechanical attachment without voiding.
