Product details
Overview
P6SMB180AHE3_B/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 180 V standoff voltage (VWM), 246 V maximum clamping voltage at 2.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control units.
For engineers reviewing the P6SMB180AHE3_B/I datasheet, P6SMB180AHE3_B/I pinout, P6SMB180AHE3_B/I application, or P6SMB180AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown when reverse voltage exceeds its breakdown threshold (VBR = 171–189 V at 1 mA), limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns).
Designed for repetitive surge events at 0.01% duty cycle, it supports peak pulse currents up to 2.4 A (10/1000 μs), with derating above 25 °C per Fig. 2 and thermal resistance values optimized for 0.2" × 0.2" copper pads per terminal. It meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping initiation across temperature and unit variation. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during full-rated transient; determines downstream component voltage stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity for 10/1000 μs waveform; enables robust protection against inductive switching surges. |
| IPPM (Peak Pulse Current) | 2.4 A - Maximum non-repetitive surge current the device can safely shunt without degradation; verified per Fig. 1 and Fig. 3. |
| TJ max. | 150 °C - Maximum junction temperature rating; sets thermal design limits for PCB layout and ambient operating conditions. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; critical for estimating temperature rise under power dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / Surge return node | Connected to ground or low-impedance reference; completes clamping loop during transient events. |
| Cathode | Protected line connection / High-side clamp input | Connected to the line being protected (e.g., 12 V rail or sensor output); reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, body electronics, and ADAS power rails. |
| 600 W peak pulse power | Handles high-energy transients from inductive load switching (e.g., solenoids, relays) without failure under defined 10/1000 μs waveform conditions. |
| Glass passivated junction | Ensures stable reverse leakage (<1 μA at VWM) and long-term parameter consistency across humidity and thermal stress. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak - eliminates moisture sensitivity concerns during assembly. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns response), improving protection fidelity for sensitive logic inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A-E3/5B | Same VWM (154 V), identical SMB package, but rated for 400 W PPPM and lower IPPM (1.5 A); no AEC-Q101 qualification. | Limited to commercial-grade industrial or consumer applications where automotive reliability is not required. | Select when cost sensitivity outweighs automotive qualification needs and surge energy is consistently ≤400 W. |
| 1.5SMC180A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs; AEC-Q101 available only in HE3 suffix variants. | Requires PCB redesign due to larger footprint and higher thermal mass; suited for higher-energy surge environments (e.g., railway or grid-connected systems). | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space allows SMC footprint. |
Compared with SMAJ180A-E3/5B and 1.5SMC180A, P6SMB180AHE3_B/I uniquely balances AEC-Q101 compliance, 600 W surge handling, and SMB footprint - making it optimal for space-constrained automotive modules where validated reliability and standardized assembly are mandatory.

FAQ
What is the breakdown voltage range for P6SMB180AHE3_B/I?
The breakdown voltage (VBR) of P6SMB180AHE3_B/I is specified as 171 V to 189 V at a test current of 1 mA. This range reflects manufacturing tolerance and ensures consistent avalanche initiation across units. The value is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's official datasheet revision 09-Jan-2024. P6SMB180AHE3_B/I maintains this specification across its full operating temperature range of -65 °C to +150 °C.
Is P6SMB180AHE3_B/I suitable for automotive applications?
Yes, P6SMB180AHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in its part number. It has passed stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD verification per automotive requirements. This makes P6SMB180AHE3_B/I appropriate for use in engine control modules, body control units, and ADAS power domains where reliability under harsh environmental conditions is mandatory.
What does the "_B/I" suffix mean in P6SMB180AHE3_B/I?
The "_B" denotes AEC-Q101 qualification for the P6SMB180AHE3_B/I device, while "/I" specifies packaging in 13-inch diameter plastic tape and reel with a 3200-unit quantity per reel. This format complies with EIA-481 standards and supports high-volume automated SMT placement. The base "HE3" suffix confirms RoHS compliance and AEC-Q101 qualification, distinguishing it from commercial-grade E3 or M3 variants.
How does P6SMB180AHE3_B/I compare to bidirectional TVS diodes like P6SMB180CA?
P6SMB180AHE3_B/I is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply rails), offering lower leakage and sharper clamping onset. In contrast, P6SMB180CA is bidirectional and used in AC-coupled or polarity-agnostic paths (e.g., data lines). Their VWM, VC, and PPPM ratings differ: P6SMB180CA has VWM = 154 V (same), but VC = 274 V and IPPM = 2.2 A - meaning P6SMB180AHE3_B/I provides tighter clamping for DC applications.
What is the maximum clamping voltage of P6SMB180AHE3_B/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB180AHE3_B/I is 246 V at a peak pulse current (IPPM) of 2.4 A, tested with a 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a full-rated transient event. It is measured under standard conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and remains valid across the device's operational temperature range when derated per Fig. 2 in the datasheet.
