Product details
Overview
P6SMB160AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 219 V at 2.7 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB160AHM3_B/H datasheet, P6SMB160AHM3_B/H pinout, P6SMB160AHM3_B/H application, or P6SMB160AHM3_B/H equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and suitability for inductive load switching surge suppression in automotive ECUs and sensor interfaces.
Technical Context
This TVS diode operates as a clamping device that diverts transient energy away from sensitive downstream circuitry by entering avalanche breakdown when reverse voltage exceeds VBR (152–168 V). Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Designed for surface-mount assembly on PCBs with 0.2" × 0.2" copper pads per terminal, it features glass-passivated junction, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. Polarity is marked by cathode band; no marking on bidirectional variants.
Key Specifications

Applications
| Automotive Power Line Protection | CAN Bus Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed control modules against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp negative transients and absorb energy. Use Value: Limits voltage excursion to ≤219 V, preventing damage to MCU power supplies and PMICs while maintaining system uptime. |
Use Scenario: Safeguarding CAN transceivers (e.g., TJA1042, SN65HVD230) from ESD and bus faults in vehicle networks. IC Role / Device Role / Timing Role: Bidirectional protection not applicable here; P6SMB160AHM3_B/H used on power supply side only, not signal lines. Use Value: Prevents latch-up or permanent failure of CAN PHY due to coupled power-rail surges, preserving communication integrity. |
| Industrial Sensor Signal Conditioning | Consumer Appliance Motor Drive Inputs |
Use Scenario: Shielding analog front-end circuits (e.g., ADC inputs, op-amp buffers) in pressure/temperature sensors exposed to relay-switched loads. IC Role / Device Role / Timing Role: Clamping diode on VDD line upstream of LDO regulator, absorbing sub-millisecond spikes before they reach precision circuitry. Use Value: Maintains ±0.1% measurement accuracy by limiting supply rail perturbation to <100 mV during transient events. |
Use Scenario: Protecting microcontroller I/O and gate drivers in washing machine or HVAC motor control boards subjected to compressor turn-off spikes. IC Role / Device Role / Timing Role: Primary overvoltage suppressor on main DC bus feeding H-bridge MOSFETs and logic rails. Use Value: Eliminates need for redundant ceramic capacitors or ferrite beads by providing deterministic 219 V clamping ceiling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/5B | Same VWM/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-power or space-constrained designs where thermal mass is less critical | Select when board area is constrained and peak pulse repetition is infrequent |
| P6SMB160AHE3_B/H | Identical electrical specs and SMB package, but RoHS-compliant commercial grade (non-AEC-Q101, non-halogen-free) | Suitable for industrial/commercial systems without automotive qualification requirements | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with P6SMB160AHM3_B/H, SMAJ160A-E3/5B trades thermal robustness for compactness, while P6SMB160AHE3_B/H retains identical form-factor and performance but omits halogen-free and AEC-Q101 compliance-making it viable only outside automotive OEM supply chains.

FAQ
What is the maximum clamping voltage of the P6SMB160AHM3_B/H under standard test conditions?
The P6SMB160AHM3_B/H has a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 2.7 A using the 10/1000 μs waveform. This value is measured at the device terminals with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160AHM3_B/H maintains this clamping performance across its operational temperature range.
Is the P6SMB160AHM3_B/H suitable for automotive applications?
Yes, the P6SMB160AHM3_B/H is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor modules. Its halogen-free construction, MSL Level 1 rating, and guaranteed performance from −65 °C to +150 °C meet stringent OEM requirements. The P6SMB160AHM3_B/H is approved for placement on power rails subject to ISO 7637-2 Pulse 1 and Pulse 2a stress profiles.
How does the P6SMB160AHM3_B/H differ from the P6SMB160AHE3_B/H variant?
The P6SMB160AHM3_B/H differs from P6SMB160AHE3_B/H in two key ways: it is halogen-free (per IEC 61249-2-21) and fully AEC-Q101 qualified, whereas P6SMB160AHE3_B/H is RoHS-compliant but lacks both halogen-free certification and automotive qualification. Electrically and mechanically, both share identical VWM, VBR, VC, package, and pinout-making them drop-in replacements only where AEC-Q101 and halogen-free status are not required. The P6SMB160AHM3_B/H is the preferred choice for Tier 1 automotive suppliers.
What is the reverse leakage current specification for the P6SMB160AHM3_B/H at its stand-off voltage?
The P6SMB160AHM3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated stand-off voltage (VWM) of 136 V and tested at 25 °C. This ultra-low leakage ensures minimal power loss and signal interference in always-on or battery-powered systems. The P6SMB160AHM3_B/H maintains leakage below 5 μA even at elevated temperatures up to 125 °C, supporting reliable operation in thermally demanding environments.
Can the P6SMB160AHM3_B/H be used in bidirectional configurations?
No, the P6SMB160AHM3_B/H is a unidirectional TVS diode, identifiable by its cathode band marking and specified only for reverse-biased clamping operation. For bidirectional protection, Vishay offers the P6SMB160CA variant (with 'CA' suffix), which provides symmetrical clamping in both polarities. Using the P6SMB160AHM3_B/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect downstream components.
