Product details
Overview
P6SMB47AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients up to 64.8 V at 9.3 A peak pulse current (10/1000 μs), with 600 W peak pulse power rating and 40.2 V stand-off voltage - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the P6SMB47AHE3/5B datasheet, P6SMB47AHE3/5B pinout, P6SMB47AHE3/5B application, or P6SMB47AHE3/5B equivalent, key selection criteria include clamping voltage (VC = 64.8 V), breakdown voltage range (44.7–49.4 V), AEC-Q101 qualification status, RoHS compliance, and SMB package thermal performance (RθJA = 100 °C/W).
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band-marked SMB package, leveraging glass-passivated junction technology for stable surge response. It delivers 600 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, and features low incremental surge resistance and fast response time to suppress ESD and inductive switching transients.
Designed for surface-mount automated assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), has matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and supports operation across -65 °C to +150 °C junction temperature range - critical for under-hood automotive and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

IC Role / Device Role / Timing Role: Primary front-end clamping element upstream of DC-DC converters and PMICs. Use Value: Handles repetitive 10/1000 μs surges up to 9.3 A while maintaining 40.2 V standoff for stable converter regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/5B | Same SMB package, identical VWM (40.2 V) and VC (64.8 V), but rated for 400 W PPPM (vs. 600 W) | Limited to lower-energy transients; not recommended for automotive load dump or industrial relay coil suppression | Select P6SMB47AHE3/5B when 600 W surge margin is required; SMAJ47A-E3/5B suits cost-sensitive consumer designs with lower threat levels |
| SMCJ47AHE3/5B | Higher-power SMC (DO-214AB) package, same VWM/VC specs, rated for 1500 W PPPM and 23.3 A IPPM | Physically larger footprint; better thermal dissipation but requires PCB area increase and layout revision | Choose SMCJ47AHE3/5B only if system-level surge testing exceeds 600 W; otherwise P6SMB47AHE3/5B provides optimal size/power balance |
Compared with SMAJ47A-E3/5B and SMCJ47AHE3/5B, P6SMB47AHE3/5B uniquely delivers 600 W clamping capability in the compact SMB footprint with AEC-Q101 qualification - making it the preferred choice for space-constrained automotive and industrial modules requiring certified reliability without SMC-level board area penalty.

FAQ
What is the clamping voltage of P6SMB47AHE3/5B at its rated peak pulse current?
The clamping voltage (VC) of P6SMB47AHE3/5B is 64.8 V at 9.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value represents the maximum voltage imposed on the protected circuit during a transient event and is measured with the device mounted on 0.2" × 0.2" copper pads per the datasheet test condition. P6SMB47AHE3/5B maintains this clamping performance across its specified operating temperature range.
Is P6SMB47AHE3/5B suitable for automotive applications?
Yes, P6SMB47AHE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix, and is explicitly intended for automotive use including engine control units, body electronics, and infotainment power rails. Its glass-passivated junction, MSL Level 1 rating, and -65 °C to +150 °C operating range meet stringent automotive reliability requirements. P6SMB47AHE3/5B is listed in Vishay's AEC-Q101 qualified product matrix for the P6SMB family.
What does the "5B" in P6SMB47AHE3/5B signify?
The "5B" suffix in P6SMB47AHE3/5B 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-compliant, AEC-Q101 qualified construction. P6SMB47AHE3/5B thus combines automotive qualification with high-volume SMT packaging optimized for automated assembly lines.
How does P6SMB47AHE3/5B differ from bidirectional variants like P6SMB47CAHE3/5B?
P6SMB47AHE3/5B is unidirectional, with polarity marked by a cathode band and intended for DC line protection where current flows in one direction - such as 12 V supply rails. In contrast, P6SMB47CAHE3/5B is bidirectional, lacks polarity marking, and protects AC or differential signal lines. Their breakdown voltages differ: P6SMB47AHE3/5B has VBR = 44.7–49.4 V, while P6SMB47CAHE3/5B has symmetric VBR ≈ 44.7–49.4 V in both directions. P6SMB47AHE3/5B cannot substitute for bidirectional use without circuit redesign.
What is the thermal resistance of P6SMB47AHE3/5B, and how does it affect layout design?
P6SMB47AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value guides PCB thermal design: for sustained 5.0 W power dissipation, ambient temperature must remain below ~100 °C to avoid exceeding the 150 °C max junction temperature. Layout best practices include maximizing copper pour on both terminals and avoiding thermal isolation - critical for P6SMB47AHE3/5B reliability in high-duty-cycle surge environments.
