Product details
Overview
P6SMB62AHM3_A/H 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 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current, 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 P6SMB62AHM3_A/H datasheet, P6SMB62AHM3_A/H pinout, P6SMB62AHM3_A/H application, or P6SMB62AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and thermal resistance of 100 °C/W (junction-to-ambient) under standard PCB pad layout.
Technical Context
This TVS diode operates as a voltage-clamping protection device that conducts above its breakdown threshold to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), while the low incremental surge resistance enables effective suppression of inductive switching spikes and ESD events.
The P6SMB62AHM3_A/H is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and supports peak forward surge current up to 100 A (8.3 ms half-sine). Its operating junction temperature range spans −65 °C to +150 °C, and it meets JESD201 Class 2 whisker resistance and J-STD-020 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed voltage range where device transitions into avalanche conduction; tight tolerance supports predictable protection threshold. |
| VC (Clamping Voltage) | 85.0 V at 7.1 A - Maximum voltage seen across protected line during 10/1000 μs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained surge energy handling capability under standardized 10/1000 μs waveform; validates robustness against lightning-induced surges. |
| IPPM (Peak Pulse Current) | 7.1 A - Peak current the device safely shunts during specified transient; directly linked to PCB trace width and layout thermal design. |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal derating limits for high-temperature ambient applications like automotive engine bays. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs heatsinking requirements for sustained surge duty cycles. |
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 | Current entry terminal during forward conduction | Connected to lower-potential side of protected line; critical for correct orientation in unidirectional clamping configuration. |
| Cathode | Current exit terminal during forward conduction; clamping node during reverse transients | Connected to higher-potential side (e.g., VCC rail); carries full surge current during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5B | Same SMB package, 64 V VBR min (60.8–67.2 V), 87.1 V VC at 6.9 A; non-AEC-Q101, commercial-grade only. | Lacks automotive qualification and halogen-free certification; suitable for cost-sensitive industrial designs without automotive compliance needs. | Select when AEC-Q101 and halogen-free requirements are not mandated, and slightly higher clamping voltage is acceptable. |
| 1.5SMC62A | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; RθJA = 50 °C/W; 1.5 kW PPPM. | Higher power handling and better thermal performance, but requires larger PCB area and different footprint. | Choose when system-level surge requirements exceed 600 W or thermal management demands lower junction temperature rise. |

FAQ
What is the clamping voltage of the P6SMB62AHM3_A/H under a 10/1000 μs surge?
The P6SMB62AHM3_A/H has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during transient events - critical for verifying margin against downstream component absolute maximum ratings. The P6SMB62AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the P6SMB62AHM3_A/H qualified for automotive applications?
Yes, the P6SMB62AHM3_A/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements - making it suitable for use in body control modules, infotainment systems, and ADAS sensor interfaces where reliability under harsh conditions is mandatory. The P6SMB62AHM3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "_A/H" suffix in P6SMB62AHM3_A/H indicate?
The "_A/H" suffix in P6SMB62AHM3_A/H specifies packaging and reel configuration: "A" denotes the revision code per Vishay's internal documentation, and "H" indicates 7-inch diameter plastic tape-and-reel delivery with 750 units per reel. This format aligns with Vishay's ordering nomenclature for the HM3 variant and ensures compatibility with standard SMT pick-and-place equipment. The P6SMB62AHM3_A/H is supplied in moisture-barrier packaging meeting MSL Level 1 requirements.
How does the thermal resistance of the P6SMB62AHM3_A/H affect PCB layout?
The P6SMB62AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate this minimum pad area and avoid excessive trace length or isolation. Reducing copper area increases RθJA, risking thermal runaway; increasing it improves dissipation but does not reduce RθJA below the specified 100 °C/W baseline. The P6SMB62AHM3_A/H thermal performance is validated only under these defined mounting conditions.
Can the P6SMB62AHM3_A/H replace bidirectional TVS diodes in circuit designs?
No - the P6SMB62AHM3_A/H is strictly unidirectional, with polarity marked by a cathode band; it conducts only in reverse bias and blocks forward current beyond its low forward voltage drop (~3.5 V at 50 A). Bidirectional operation requires CA-suffixed variants (e.g., P6SMB62CA). Substituting the P6SMB62AHM3_A/H in a bidirectional application would result in improper clamping during positive-going transients and potential device failure. Always verify polarity alignment and transient directionality before selecting the P6SMB62AHM3_A/H.
