Product details
Overview
P6SMB130CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 111 V stand-off voltage (VWM), 124–137 V breakdown voltage (VBR) at 1 mA test current, 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB130CA-E3/52 datasheet, P6SMB130CA-E3/52 pinout, P6SMB130CA-E3/52 application, or P6SMB130CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.44), RoHS-compliant matte tin plating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast transient response under repetitive 0.01% duty cycle conditions.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout. Its 600 W peak pulse power handling is validated under standardized 10/1000 μs waveform testing, with derating applied above 25 °C ambient per Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - guaranteed conduction onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 179 V at 3.4 A IPPM - peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for short-duration surges; enables robust protection against lightning-induced or inductive-switching transients |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint; optimized for automated assembly and thermal dissipation |
| RoHS Compliance | E3 suffix - lead-free, RoHS-compliant matte tin plating; meets J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2 |
| MSL Rating | Level 1 (per J-STD-020) - unlimited floor life at ≤30 °C/60% RH; no bake requirement prior to reflow |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with UL 94 V-0 flammability rating; cathode/anode terminals are unmarked for bidirectional types - polarity is non-directional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | One terminal of symmetrical PN junction; accepts surge current regardless of polarity relative to cathode |
| Cathode | Transient current exit (bidirectional) | Second terminal of symmetrical PN junction; completes low-impedance path during clamping in either direction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses (e.g., RS-485), or floating sensor inputs without external polarity management |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surge (4 kV line-earth) when properly laid out on 5.0 mm × 5.0 mm copper pads |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime; reduces parameter drift versus epoxy-passivated alternatives |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot during clamping - critical for protecting 130 V-rated components with narrow safety margins |
| Automated placement compatibility | Low-profile SMB package with defined lead coplanarity and matte tin terminations supports high-yield pick-and-place and reflow |
Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-T | Same VWM (111 V), identical SMB package, but higher VC = 219 V at 2.7 A IPPM; lower peak pulse current rating | Less effective clamping margin for 130 V systems; requires higher PCB trace width to sustain same energy | Select when legacy design uses SMBJ series footprint and lower cost outweighs clamping performance loss |
| 1.5KE130CA | Through-hole DO-201 package; same VWM/VC specs but larger footprint and manual assembly requirement | Not suitable for high-density SMT layouts; limited to prototyping or low-volume industrial controls | Choose only if board redesign is impractical and through-hole assembly infrastructure is already in place |
Compared with SMBJ130CA-T and 1.5KE130CA, P6SMB130CA-E3/52 delivers superior clamping ratio (1.44 vs. 1.66), tighter VBR tolerance (±5% vs. ±10%), and full SMT compatibility - making it optimal for space-constrained, high-reliability industrial and automotive electronics where precise voltage limiting and automated manufacturing are required.

FAQ
What is the maximum clamping voltage of P6SMB130CA-E3/52 under standard test conditions?
The maximum clamping voltage (VC) of P6SMB130CA-E3/52 is 179 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 3.4 A. This value is measured at TA = 25 °C with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per the datasheet's recommended layout - ensuring consistent thermal and electrical performance in production designs using P6SMB130CA-E3/52.
Is P6SMB130CA-E3/52 suitable for automotive applications?
P6SMB130CA-E3/52 is RoHS-compliant and qualified to MSL Level 1, but it is not AEC-Q101 certified. For automotive use, Vishay offers the P6SMB130CAHE3_B variant (with HE3 suffix), which adds AEC-Q101 qualification. Engineers must specify the HE3 version explicitly when designing for automotive ECUs or ADAS modules - P6SMB130CA-E3/52 itself is intended for industrial and telecom applications where AEC-Q101 is not mandated.
How does the bidirectional nature of P6SMB130CA-E3/52 affect its circuit placement?
Because P6SMB130CA-E3/52 is bidirectional, it has no polarity marking and can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (RS-485, CAN), AC power inputs, or floating sensor bridges. Unlike unidirectional TVS diodes, P6SMB130CA-E3/52 eliminates orientation errors during assembly and avoids forward conduction issues on negative-going transients, simplifying layout and validation for P6SMB130CA-E3/52 deployments.
What is the thermal resistance of P6SMB130CA-E3/52, and how does it impact power derating?
P6SMB130CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended pad layout. This means power dissipation must be derated linearly above 25 °C ambient - for example, at 75 °C ambient, the allowable continuous power drops to 2.5 W (5.0 W × [1 − (75−25)/100]). The 100 °C/W RθJA directly governs thermal design margins for P6SMB130CA-E3/52 in enclosed or high-temperature environments.
Can P6SMB130CA-E3/52 replace older P6KE130CA parts in existing designs?
P6SMB130CA-E3/52 is not a direct drop-in replacement for through-hole P6KE130CA due to its SMB (DO-214AA) surface-mount package versus DO-15. While electrical specs (VWM, VBR, VC) align closely, the footprint change requires PCB revision. However, P6SMB130CA-E3/52 offers improved surge robustness (600 W vs. 600 W nominal but lower actual clamping), better thermal performance in SMT assemblies, and RoHS compliance - justifying redesign for new P6SMB130CA-E3/52-based platforms.
