Product details
Overview
P6SMB160AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB160AHE3_A/I datasheet, P6SMB160AHE3_A/I pinout, P6SMB160AHE3_A/I application, or P6SMB160AHE3_A/I equivalent, this part is selected for high-energy surge immunity in automotive-grade (AEC-Q101 qualified), RoHS-compliant, SMB-packaged transient protection where precise clamping voltage and low leakage (<1.0 μA at VWM) are critical.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp, activating when transient voltage exceeds its 179–189 V breakdown range (tested at 1.0 mA). Its glass-passivated junction ensures stable VBR temperature coefficient (0.108 %/°C) and fast response time (<1.0 ns), enabling suppression of ESD, lightning-induced surges, and inductive switching spikes before downstream components are damaged.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, requiring PCB copper pad thermal management per recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) layout. The device is rated for TJ = –65 to +150 °C operation and meets MSL Level 1 (260 °C reflow peak), supporting automated SMT assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1.0 mA - Avalanche onset threshold; tight 10.5 % tolerance ensures predictable turn-on behavior. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream devices. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity under standardized 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 3/4 surges. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby current draw; avoids loading sensitive reference or bias networks. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TC, HTRB, and ESD; suffix HE3 denotes qualification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events (IFSM = 100 A). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or signal input); avalanche breakdown occurs here during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables single-device protection against high-energy transients per IEC 61000-4-5, eliminating need for cascaded TVS or MOV solutions. |
| Glass passivated junction | Ensures long-term parameter stability and low leakage drift across temperature and lifetime, critical for safety-critical automotive modules. |
| MSL Level 1 rating | Supports standard Pb-free reflow profiles up to 260 °C peak without baking, reducing manufacturing complexity and cost. |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic-level ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/5B | Same VWM (136 V), VC = 221 V, IPPM = 2.7 A, but lower PPPM (400 W); SMA package (DO-214AC), smaller footprint. | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4; preferred where board space is constrained. | Select SMAJ160A-E3/5B only if surge energy is ≤400 W and PCB real estate is premium; verify thermal derating for continuous operation. |
| 1.5KE160A | Through-hole DO-201 package; same VWM/VC specs but higher RθJA (70 °C/W), no AEC-Q101 qualification, leaded construction. | Not suitable for automated SMT production or automotive use; requires wave soldering and larger board area. | Choose 1.5KE160A only for legacy through-hole designs or prototyping where reflow compatibility and automotive compliance are not required. |
Compared with SMAJ160A-E3/5B and 1.5KE160A, P6SMB160AHE3_A/I delivers superior surge handling (600 W vs. 400 W/1500 W), AEC-Q101 qualification for automotive deployment, and optimized thermal performance in SMB packaging - making it the preferred choice for volume SMT production of industrial and automotive electronics requiring validated reliability.

FAQ
What is the clamping voltage of P6SMB160AHE3_A/I at its rated peak pulse current?
The P6SMB160AHE3_A/I has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 2.7 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB160AHE3_A/I achieves this with low incremental resistance, minimizing overshoot beyond VC.
Is P6SMB160AHE3_A/I suitable for automotive applications?
Yes, P6SMB160AHE3_A/I is AEC-Q101 qualified, as confirmed by its "HE3" suffix and Vishay's documentation. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress testing (HAST) to ensure reliability in automotive environments such as engine bays and chassis modules. The P6SMB160AHE3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the P6SMB family.
What does the "_A/I" suffix in P6SMB160AHE3_A/I indicate?
The "_A/I" suffix in P6SMB160AHE3_A/I specifies packaging and reel configuration: "A" denotes the standard revision level per Vishay's internal change control, and "I" indicates 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel. This format supports high-volume SMT placement and is compatible with industry-standard pick-and-place equipment - distinct from the "H" (7-inch reel, 750 units) variant.
How does P6SMB160AHE3_A/I differ from bidirectional variants like P6SMB160CA?
P6SMB160AHE3_A/I is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, P6SMB160CA is bidirectional, offering symmetrical clamping for AC or floating signal lines - but with lower VWM (136 V vs. 136 V) and reduced VBR range (152–168 V vs. 152–168 V for unidirectional, though bidirectional VBR is specified differently). The P6SMB160AHE3_A/I cannot replace P6SMB160CA in AC-coupled circuits without redesign.
What is the maximum operating temperature for P6SMB160AHE3_A/I?
The P6SMB160AHE3_A/I has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. This rating enables deployment in under-hood automotive modules and industrial enclosures exposed to elevated ambient temperatures. Derating curves in the datasheet show that peak pulse power must be reduced above TA = 25 °C, with 50 % derating at TA = 100 °C - a key consideration when designing thermal pads for the P6SMB160AHE3_A/I.
