Product details
Overview
P6SMB160A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal paths. It features a standoff voltage of 136 V, breakdown voltage range of 152–168 V at 1 mA test current, clamping voltage of 219 V at 2.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It is used in switching mode power supplies and industrial adapters to absorb ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB160A datasheet, P6SMB160A pinout, P6SMB160A application, or P6SMB160A equivalent, key selection criteria include its 136 V working voltage, 219 V clamping performance under 10/1000 µs surge, DO-214AA (SMB) package compatibility with automated placement, and compliance with J-STD-020 Level 1 moisture sensitivity.
Technical Context
The P6SMB160A employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps rise time from 0 V to VBR(min)) and low leakage (<1 µA at 136 V). Its unidirectional configuration provides asymmetric conduction-forward voltage is 5.0 V at 50 A-while maintaining bidirectional surge immunity per ISO 7637-2 test pulses.
Thermal design is supported by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling reliable operation up to 150 °C junction temperature. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards, confirming suitability for high-reliability industrial PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC bias margin. |
| VBR (min/max) | 152 V / 168 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients. |
| VC @ IPPM | 219 V at 2.8 A (10/1000 µs) - Clamping voltage limiting downstream circuit stress during standardized surge events. |
| PPPSM | 600 W - Peak pulse power rating for non-repetitive 10/1000 µs waveform; determines single-event energy absorption capacity. |
| Junction Temp | –55 °C to +150 °C - Operating range validated for automotive-grade ambient environments and thermally constrained layouts. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline with 0.090 g mass; compatible with J-STD-002 soldering and automated pick-and-place. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode band marking polarity, UL 94V-0 rated compound, and JESD201 Class 2 whisker resistance. Weight ≈ 0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive surges when cathode is biased higher. |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential rail; initiates avalanche breakdown above VWM to shunt surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 219 V max clamping at 2.8 A (10/1000 µs), delivering precise overvoltage limiting without sacrificing response speed. |
| Leakage control | <1 µA reverse leakage at 136 V, minimizing standby power loss in always-on power rails and sensor interfaces. |
| Transient immunity | Validated against ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), ensuring automotive-compliant robustness. |
| Manufacturing readiness | DO-214AA (SMB) package with J-STD-002 solderability and Level 1 moisture sensitivity-enabling high-yield reflow assembly without baking. |
Applications
| Switching Mode Power Supply (SMPS) | Industrial Adapter |
|---|---|
Use Scenario: Protection of primary-side DC bus against inductive kickback and line surges in offline AC/DC converters. IC Role / Device Role / Timing Role: Unidirectional TVS placed across bulk capacitor input to clamp transient spikes before they reach controller ICs or MOSFETs. Use Value: Limits voltage excursions to ≤219 V during 600 W surges, preventing gate oxide damage to 600 V MOSFETs and ensuring stable PWM controller operation. |
Use Scenario: Input-stage surge suppression in universal-input 12–24 V industrial wall adapters exposed to mains-borne transients. IC Role / Device Role / Timing Role: Standoff-rated TVS on secondary-side DC output to protect connected PLC I/O modules from backfeed surges. Use Value: Maintains 136 V working margin while clamping to 219 V, preserving regulated output integrity during 10/1000 µs line disturbances. |
| Television Power Board | Monitor DC Input Stage |
Use Scenario: Overvoltage guard on main 12 V/24 V power rail feeding backlight inverters and audio amplifiers in flat-panel TVs. IC Role / Device Role / Timing Role: Fast-response TVS absorbing ESD and lightning-induced surges coupled through external AV inputs or USB service ports. Use Value: Sub-nanosecond turn-on ensures clamping occurs before transient energy reaches sensitive TCON or SoC power domains. |
Use Scenario: DC input protection for LCD monitor power boards receiving 19 V from external brick adapters. IC Role / Device Role / Timing Role: Unidirectional suppressor between adapter jack and upstream buck converter input capacitor. Use Value: 219 V clamping prevents overvoltage tripping of OVP circuits while sustaining <1 µA leakage to avoid standby current violations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same DO-214AA package, identical VWM (136 V), but slightly higher VC = 230 V at 2.8 A. | Marginally reduced clamping headroom; suitable where layout allows minor voltage tolerance increase. | Select SMBJ160A only if existing design already uses SMBJ-series footprint and thermal derating accommodates +11 V clamping delta. |
| 1.5SMC160A | Larger DO-214AB (SMC) package (higher RθJA = 40 °C/W), same electrical specs but 1.5 kW peak power rating. | Over-specified power handling; requires PCB pad redesign and occupies ~30% more area. | Choose 1.5SMC160A only when system-level surge testing demands >600 W margin or long-duration repetitive transients are expected. |
Compared with SMBJ160A and 1.5SMC160A, the P6SMB160A delivers optimal balance of clamping precision (219 V), compact DO-214AA footprint, and verified ISO 7637-2 compliance-making it preferred for space-constrained, cost-sensitive industrial and consumer power designs requiring repeatable 600 W surge protection.

FAQ
What is the maximum clamping voltage of the P6SMB160A under standard 10/1000 µs surge conditions?
The P6SMB160A has a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 2.8 A. This value is measured per ANSI/IEEE C62.35 and confirmed in TSC's Q2209 datasheet revision-ensuring consistent overvoltage limiting for downstream components in real-world surge events.
Is the P6SMB160A suitable for bidirectional transient protection?
No, the P6SMB160A is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional applications, TSC specifies the P6SMB160CA variant (with 'CA' suffix); the P6SMB160A lacks symmetrical breakdown characteristics and must be oriented correctly to function as specified.
Does the P6SMB160A meet automotive transient immunity standards?
Yes, the P6SMB160A is explicitly validated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements-covering load dump, switch-off transients, and capacitive coupling events common in 12 V and 24 V automotive electrical systems.
What is the forward voltage drop of the P6SMB160A at high surge current?
The P6SMB160A exhibits a forward voltage (VF) of 5.0 V at 50 A for unidirectional conduction, as specified in the Absolute Maximum Ratings table. This parameter applies only during forward-biased surge events and confirms low conduction loss during high-current fault conditions.
How does the P6SMB160A's thermal resistance affect PCB layout decisions?
With RθJA = 55 °C/W and RθJC = 10 °C/W, the P6SMB160A requires adequate copper pour on the cathode pad and minimal trace length to maintain junction temperature below 150 °C under repeated surges. Layouts should avoid enclosing the DO-214AA body in tight thermal islands to prevent localized overheating.
