Product details
Overview
P6SMB180AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 180 V standoff voltage (VWM), 246 V clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the P6SMB180AHE3/5B datasheet, P6SMB180AHE3/5B pinout, P6SMB180AHE3/5B application, or P6SMB180AHE3/5B equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) for board-level thermal design validation.
Technical Context
The P6SMB180AHE3/5B operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transient surges before IC damage occurs. Its breakdown voltage (VBR) is specified at 171–189 V (min/max) with 1 mA test current, and it maintains stable clamping performance across -65 °C to +150 °C junction temperature range.
Designed for automated SMT placement, the device meets J-STD-020 MSL Level 1 (peak reflow 260 °C), uses matte tin-plated leads per JESD 22-B102, and supports repetitive 0.01% duty cycle transients. The cathode band identifies polarity, and its SMB package enables compact layout with 0.2" × 0.2" copper pad thermal management per Vishay's recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature leakage. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability under standardized 10/1000 μs waveform; validates protection against IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; requires minimum 0.2" × 0.2" copper pads for rated power dissipation at TA = 50 °C. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded UL 94 V-0 compound and cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential rail in unidirectional TVS configuration. | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., 12 V supply or CAN_H). | Band-marked end; reverse-biased during normal operation; conducts only during overvoltage events to shunt surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress. |
| 600 W peak pulse power (10/1000 μs) | Supports protection against severe lightning-induced surges and inductive switching spikes in 12 V/24 V systems. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or special handling requirements. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD or EFT), improving system immunity. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface 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 |
|---|---|---|---|
| SMAJ180A-E3/5B | Same VWM (154 V), VC = 246 V, but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Less suitable for high-energy surges (e.g., ISO 7637-2 Pulse 5); preferred where board space is constrained and surge energy ≤400 W. | Select SMAJ180A-E3/5B only when thermal budget allows higher junction temperature rise and peak power demand is ≤400 W. |
| 1.5SMC180A | Same electrical specs (VWM = 154 V, VC = 246 V, PPPM = 600 W), but SMC (DO-214AB) package - larger footprint, lower RθJA = 75 °C/W. | Better thermal performance for high-duty-cycle or high-ambient applications; not drop-in compatible due to different pad layout and height. | Choose 1.5SMC180A when sustained surge repetition or ambient >85 °C requires improved thermal dissipation, accepting larger PCB area. |
Compared with SMAJ180A-E3/5B, P6SMB180AHE3/5B delivers 50% higher surge energy handling in the same SMB footprint; versus 1.5SMC180A, it trades thermal margin for space savings - critical for dense automotive ECUs where board real estate is premium.

FAQ
What is the clamping voltage of P6SMB180AHE3/5B at its rated peak pulse current?
The P6SMB180AHE3/5B has a maximum clamping voltage (VC) of 246 V at 2.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88370, and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB180AHE3/5B maintains this clamping performance across its full operating temperature range.
Is P6SMB180AHE3/5B qualified for automotive applications?
Yes, P6SMB180AHE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD per AEC standards. The device is explicitly listed in Vishay's documentation for use in automotive ECUs and sensor units, and its thermal rating (TJ max = +150 °C) supports under-hood deployment. P6SMB180AHE3/5B meets automotive reliability requirements without derating.
What does the "5B" in P6SMB180AHE3/5B signify?
The "5B" suffix in P6SMB180AHE3/5B denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This differs from "52", which indicates a 7-inch reel with 750 units. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "A" specifies unidirectional polarity. All elements - P6SMB180AHE3/5B - are required to ensure correct ordering of the qualified, high-volume production variant.
How does the SMB package of P6SMB180AHE3/5B compare thermally to larger packages like SMC?
The SMB (DO-214AA) package of P6SMB180AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured on 0.2" × 0.2" copper pads. In contrast, the SMC (DO-214AB) package used in equivalents like 1.5SMC180A achieves ~75 °C/W due to larger pad area and thermal mass. As a result, P6SMB180AHE3/5B requires strict adherence to Vishay's recommended footprint to sustain its 5.0 W power dissipation rating at TA = 50 °C - making thermal layout verification essential.
Can P6SMB180AHE3/5B be used in bidirectional configurations?
No, P6SMB180AHE3/5B is a unidirectional TVS diode, as confirmed by its "A" suffix and cathode band marking. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB180CA). Using P6SMB180AHE3/5B in a bidirectional application would result in forward conduction during negative transients, causing failure. For AC-coupled or symmetrical surge protection, select a verified bidirectional part - P6SMB180AHE3/5B is designed exclusively for DC rail protection with defined polarity.
