Product details
Overview
P6SMB130A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 130 V standoff voltage (VWM), 179 V maximum clamping voltage at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6SMB130A-E3/5B datasheet, P6SMB130A-E3/5B pinout, P6SMB130A-E3/5B application, or P6SMB130A-E3/5B equivalent, key selection criteria include unidirectional polarity, 130 V VWM rating, 179 V VC clamping performance, RoHS-compliant matte tin terminals, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This TVS diode operates as a voltage-clamping protection device across DC power rails and low-speed signal paths. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable breakdown behavior under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device exhibits a 0.107 %/°C temperature coefficient of VBR and is rated for -65 °C to +150 °C operating junction temperature. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead) when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1.0 mA test current - Tight 13 V window ensures predictable turn-on threshold for transient suppression. |
| VC (Clamping Voltage) | 179 V at 3.4 A IPPM - Limits downstream voltage stress during ESD or load-switching surges to protect 150 V-rated components. |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - Sustains high-energy transients common in automotive and industrial environments. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current avoids power loss or false triggering in low-power systems. |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial enclosures without derating. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated placement; 5.59 mm × 4.06 mm body with 2.18 mm min. cathode band width. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, qualified to MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Enables unidirectional clamping only during reverse overvoltage events; not used for forward conduction in normal operation. |
| Cathode | Current exit point in forward bias; marked by band; connected to higher-potential side (e.g., VCC or signal line) | Defines polarity-sensitive placement - reversal causes permanent failure under overvoltage; critical for correct PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients from inductive switching (e.g., solenoid drivers) without degradation over 100,000+ events. |
| 179 V clamping voltage at 3.4 A | Provides 29 V headroom below 208 V system-level surge immunity thresholds (IEC 61000-4-5 Level 3), ensuring robust protection. |
| Glass passivated chip junction | Delivers stable leakage and breakdown characteristics across -65 °C to +150 °C, eliminating moisture-induced parameter drift. |
| AEC-Q101 qualification path | HE3/HM3 variants support automotive applications (e.g., body control modules); P6SMB130A-E3/5B shares identical die and construction. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking - reduces manufacturing overhead in high-volume SMT lines. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5B | Same VWM (111 V), VC (179 V), and PPPM (600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Lower thermal mass limits sustained pulse repetition; less suitable for high-duty-cycle industrial environments | Select when board space is constrained and thermal management uses larger copper pours or forced air. |
| 1.5SMC130A | Identical electrical specs but in larger SMC (DO-214AB) package; RθJA = 65 °C/W; 1.5 kW peak power rating | Higher thermal capacity supports higher average power dissipation; requires 2.5× more PCB area than SMB | Choose for legacy designs requiring drop-in replacement or where ambient temperature exceeds 105 °C. |

FAQ
What is the maximum clamping voltage of the P6SMB130A-E3/5B under specified test conditions?
The P6SMB130A-E3/5B has a maximum clamping voltage (VC) of 179 V at 3.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 179 V during transient events, provided the device is mounted per the recommended 5.0 mm × 5.0 mm copper pad layout. The P6SMB130A-E3/5B maintains this clamping performance across its full operating temperature range.
Is the P6SMB130A-E3/5B suitable for automotive applications?
The P6SMB130A-E3/5B itself is RoHS-compliant commercial-grade, but Vishay offers AEC-Q101-qualified variants under HE3 and HM3 suffixes (e.g., P6SMB130AHE3_B). These share identical die, packaging, and electrical characteristics with the P6SMB130A-E3/5B and are validated for automotive use including under-hood environments. For production automotive designs, specify the HE3/HM3 version; the P6SMB130A-E3/5B serves as a direct functional and layout-compatible reference.
How does the P6SMB130A-E3/5B differ from bidirectional TVS diodes like P6SMB130CA?
The P6SMB130A-E3/5B is unidirectional and conducts only during reverse-biased overvoltage events, with polarity-sensitive mounting (cathode band toward higher potential). In contrast, P6SMB130CA is bidirectional and suppresses transients in both directions - useful for AC lines or differential signals. The P6SMB130A-E3/5B offers lower leakage (<1.0 μA at VWM) and tighter VBR tolerance versus bidirectional versions, making it preferred for DC power rail protection where polarity is fixed.
What is the thermal resistance of the P6SMB130A-E3/5B, and how does it affect layout?
The P6SMB130A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain reliability under repetitive surges, PCB layout must replicate this pad size - undersized pads increase junction temperature, accelerating parameter drift and reducing surge lifetime. The P6SMB130A-E3/5B's low RθJL also supports thermal coupling to internal ground planes.
Can the P6SMB130A-E3/5B be used in parallel for higher power handling?
No - the P6SMB130A-E3/5B is not designed for parallel operation due to VBR mismatch between units, which causes current imbalance and premature failure of the lowest-VBR device. For higher power requirements, select a single higher-rated part (e.g., 1.5SMC130A) or implement staged protection with upstream MOVs. The P6SMB130A-E3/5B's 600 W rating is optimized for standalone use in standard SMB footprints, and paralleling voids Vishay's reliability specifications.
