Product details
Overview
PTVS8V5S1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features VRWM = 8.5 V, VBR(min) = 9.44 V at IR = 1 mA, VCL(max) = 14.4 V at IPPM = 27.8 A (10/1000 μs), and IRM ≤ 0.01 μA - enabling robust protection of 9–12 V automotive and industrial power inputs.
For engineers reviewing the PTVS8V5S1UR,115 datasheet, PTVS8V5S1UR,115 pinout, PTVS8V5S1UR,115 application, or PTVS8V5S1UR,115 equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current handling under IEC 61643-321 waveform, thermal resistance to PCB, and AEC-Q101 qualification status per revision history.
Technical Context
This unidirectional TVS operates as a clamping device: reverse-biased during normal operation with sub-10 nA leakage, then avalanching sharply at breakdown to limit transient voltages. Its junction-to-solder-point thermal resistance is 18 K/W, supporting sustained surge dissipation when mounted on standard FR4 with cathode pad enhancement.
The device complies with IEC 61643-321 (10/1000 μs waveform) and achieves 30 kV ESD contact discharge rating per IEC 61000-4-2. Per revision v.4 (Dec 2025), PTVS8V5S1UR,115 retains AEC-Q101 qualification - confirmed in Section 11 and Revision History Table 9.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.5 V - maximum continuous reverse operating voltage before significant leakage; sets upper bound for protected rail voltage. |
| VBR (min) | 9.44 V at IR = 1 mA - guaranteed avalanche initiation threshold; ensures reliable turn-on before downstream IC damage. |
| VCL (max) | 14.4 V at IPPM = 27.8 A - worst-case clamped voltage during 10/1000 μs surge; must stay below IC absolute max ratings. |
| PPPM | 400 W - rated peak pulse power per IEC 61643-321; defines single-event energy absorption capability. |
| IRM | ≤ 0.01 μA at VRWM - ultra-low leakage preserves battery life and avoids false triggering in low-power systems. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point; enables effective heat transfer to PCB copper for repeated surges. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - exceeds automotive EMC requirements for board-level ESD immunity. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); carries surge current into ground path during clamping. |
| 2 | Anode (A) | Connected to circuit ground; completes conduction path during transient events; requires low-inductance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power supply applications per latest revision v.4 (Dec 2025), including temperature cycling and HTRB. |
| Low-profile SOD123W | 1.0 mm max height enables use in space-constrained modules (e.g., ECUs, ADAS sensors) without mechanical interference. |
| 400 W peak pulse power | Handles high-energy transients such as ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 3a/b (switching noise) in 12 V systems. |
| Sub-10 nA reverse leakage | Minimizes quiescent current draw in always-on vehicle networks (e.g., CAN standby, LIN sleep mode), preserving battery charge. |
| 30 kV ESD contact rating | Eliminates need for additional board-level ESD protection on exposed connectors or buttons in infotainment and control panels. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: Protecting 12 V power input of engine control unit (ECU) against load dump transients up to 35 V and 100 ms duration. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between battery rail and DC-DC converter input, conducting only during overvoltage events. Use Value: Limits voltage to ≤14.4 V during 27.8 A surge, preventing damage to upstream LDOs and microcontrollers rated for 16 V absolute max. |
Use Scenario: Safeguarding 24 V digital input channel of programmable logic controller against field-wiring induced surges and inductive kickback. IC Role / Device Role / Timing Role: Standoff protector across input terminal and common ground, absorbing fast-rising transients before signal conditioning circuitry. Use Value: Clamps 1 kV/1 A surge (IEC 61000-4-5) within 1 ns, maintaining input logic state integrity and avoiding false triggering of optocouplers. |
| USB-C Power Delivery Line | Smart Sensor Node Power Supply |
|
Use Scenario: Overvoltage suppression on VBUS line of USB-C receptacle in automotive infotainment head unit, exposed to hot-plug and adapter faults. IC Role / Device Role / Timing Role: Primary front-end TVS in series with fuse and common-mode choke, shunting surge energy to chassis ground. Use Value: Withstands 400 W pulses while adding <1 pF capacitance, preserving USB 2.0 signal integrity and meeting USB-IF ESD compliance. |
Use Scenario: Protecting lithium-thionyl chloride (Li-SOCl₂) powered wireless sensor node in remote industrial monitoring, where battery replacement is impractical. IC Role / Device Role / Timing Role: Low-leakage standoff protector on main 3.6 V supply rail, activated only during lightning-induced coupling on long sensor cables. Use Value: 0.01 μA IRM extends 10-year battery life; 14.4 V clamping prevents brownout reset of ultra-low-power MCU during 20 A surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A | Same VRWM (8.5 V), but lower PPPM (400 W vs. SMAJ8.5A's 400 W), higher VCL (15.0 V), and SMA package (3.5 mm height). | Not AEC-Q101 qualified; lacks automotive validation and 30 kV ESD rating. | Use only in non-automotive industrial designs where board height >1 mm is acceptable and ESD immunity is secondary. |
| 1.5SMC8.5A | Higher VRWM tolerance (±5 % vs. ±3.5 %), larger DO-214AB package (7.1 mm × 6.2 mm), Rth(j-a) = 22 K/W (vs. 70 K/W for SOD123W). | Designed for high-power AC/DC front-ends; unsuitable for space-constrained automotive PCBs. | Select when surge repetition rate is high and thermal mass from large copper pour is available - not for compact ECU modules. |
Compared with SMAJ8.5A and 1.5SMC8.5A, PTVS8V5S1UR,115 delivers identical power rating in a 60 % smaller footprint, certified AEC-Q101 reliability, and superior ESD robustness - making it the optimal choice for next-generation automotive and miniaturized industrial electronics.

FAQ
Is PTVS8V5S1UR,115 qualified for automotive use per AEC-Q101?
Yes. Per Section 11 ("Test information") and Revision History Table 9 (v.4, Dec 2025), PTVS8V5S1UR,115 is explicitly listed among the 33 products retaining AEC-Q101 qualification - covering stress tests including HTGB, HTRB, and temperature cycling. This confirms suitability for under-hood and cabin ECU applications.
What is the maximum clamping voltage under full-rated surge current?
At IPPM = 27.8 A (10/1000 μs waveform), the maximum clamping voltage VCL is 14.4 V, as specified in Table 8. This value is measured at Tj = 25 °C and guarantees safe operation for downstream ICs with 16 V absolute maximum ratings on their supply pins.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W when soldered to a 1 cm² cathode pad on FR4 - significantly better than standard SOD-123 (Rth(j-a) ≈ 70 K/W). This enables repeated 400 W surges without junction overheating, provided PCB layout follows Nexperia's recommended footprint in Figure 6.
Can PTVS8V5S1UR,115 replace PTVS8V0S1UR in an existing design?
Yes, with verification. Both share identical package, pinout, and PPPM rating, but VRWM differs (8.0 V vs. 8.5 V) and VCL rises slightly (13.6 V → 14.4 V). Confirm that the 0.5 V higher standoff and 0.8 V higher clamping remain within system margins - especially for 9 V nominal rails with tight tolerance windows.
