Product details
Overview
SMBJ60D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 60 V stand-off voltage (VWM), 67.7–72.7 V breakdown voltage (VBR) at 1 mA, 95.5 V maximum clamping voltage (VC) at 6.28 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in industrial motor drives, telecom power supplies, and automotive body control modules.
For engineers reviewing the SMBJ60D-M3/H datasheet, SMBJ60D-M3/H pinout, SMBJ60D-M3/H application, or SMBJ60D-M3/H equivalent, key selection criteria include clamping performance under 6.28 A surge, thermal resistance (RθJA = 125 °C/W on minimum pad), unidirectional polarity with cathode band marking, and M3/H halogen-free RoHS-compliant packaging for high-reliability PCB assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (67.7–72.7 V), it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its low incremental surge resistance ensures stable clamping during repetitive 10/1000 μs surges up to 0.01 % duty cycle.
Designed for surface-mount automation, SMBJ60D-M3/H meets J-STD-020 MSL Level 1, withstands 260 °C lead-free reflow, and uses matte tin-plated leads compliant with JESD 22-B102 whisker testing. The device is rated for -55 °C to +150 °C junction temperature and derates linearly above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 48 V systems. |
| VBR (Breakdown Voltage) | 67.7–72.7 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots. |
| VC (Clamping Voltage) | 95.5 V at IPPM = 6.28 A - limits transient voltage seen by protected circuit during 600 W surge event. |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - sustains single high-energy transients like ISO 7637-2 Pulse 1/2a without failure. |
| ID (Reverse Leakage) | ≤0.5 μA at 60 V - negligible standby power loss and minimal impact on high-impedance sensor bias networks. |
| RθJA | 125 °C/W on minimum recommended pad - requires thermal-aware PCB layout (e.g., ≥5 mm² copper pour) for sustained 1 W dissipation. |
| Polarity | Unidirectional - cathode band denotes terminal to be connected toward positive rail; blocks forward conduction. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, M3 grade (JESD 201 Class 2 whisker resistant), matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode | Reference return path | Connected to system ground or low-impedance return plane; completes clamping current loop. |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise coordination with downstream overvoltage thresholds without guard-banding design margins. |
| 600 W peak pulse power | Withstands automotive load-dump surges (ISO 16750-2) and industrial inductive switching transients without degradation. |
| Low 0.5 μA leakage at VWM | Preserves battery life in always-on systems and avoids false triggering in high-impedance analog front-ends. |
| MSL Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and handling risk. |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial enclosures and telecom equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-M3/H | Bidirectional variant; symmetrical VBR (67.7–72.7 V) in both polarities; no cathode band marking. | Required where AC-coupled lines or bidirectional data buses (e.g., RS-485) need protection without polarity constraints. | Select SMBJ60A-M3/H only if circuit lacks defined DC polarity or handles AC signals; SMBJ60D-M3/H is preferred for DC rail protection. |
| SMCJ60A | Larger SMC (DO-214AB) package; higher 1500 W PPPM rating; RθJA = 40 °C/W on same pad area. | Suitable for higher-energy transients (e.g., 10/1000 μs 15 A surges) where PCB space allows larger footprint. | Choose SMCJ60A only when 600 W is insufficient and thermal budget permits larger package; SMBJ60D-M3/H offers optimal density for 600 W-class protection. |
Compared with SMBJ60A-M3/H and SMCJ60A, SMBJ60D-M3/H delivers unidirectional clamping in the smallest standard footprint (SMB), enabling compact placement near IC power pins while maintaining precise 60 V standoff and industry-standard 600 W surge capability - ideal for space-constrained DC power rail protection.

FAQ
What is the maximum clamping voltage of SMBJ60D-M3/H at its rated peak pulse current?
The SMBJ60D-M3/H has a maximum clamping voltage (VC) of 95.5 V at its rated peak pulse current (IPPM) of 6.28 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 600 W transient event, ensuring downstream components remain within safe operating voltage ranges.
Is SMBJ60D-M3/H suitable for use in automotive applications per ISO 7637-2?
Yes, SMBJ60D-M3/H is suitable for automotive applications per ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 2a (sudden load disconnection), given its 600 W peak pulse rating, 95.5 V clamping voltage, and operation over -55 °C to +150 °C junction temperature. It is commonly deployed on 12 V and 48 V board nets in body control modules and infotainment power domains.
Does SMBJ60D-M3/H have a bidirectional variant, and how does it differ?
Yes, the bidirectional variant is SMBJ60A-M3/H. Unlike SMBJ60D-M3/H, which is unidirectional and marked with a cathode band, SMBJ60A-M3/H provides symmetrical clamping in both polarities, has identical VBR and VC specs, but lacks polarity marking and is used on AC or polarity-agnostic lines such as RS-485 or antenna ports.
What is the thermal resistance of SMBJ60D-M3/H, and how does it affect PCB layout?
SMBJ60D-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended pad layout. This necessitates careful PCB thermal design - such as using ≥5 mm² copper pour connected to the anode/cathode pads - to maintain junction temperature below 150 °C during sustained 1 W power dissipation or repetitive surge events.
How does the M3/H suffix impact compliance and manufacturability of SMBJ60D-M3/H?
The M3/H suffix indicates SMBJ60D-M3/H is halogen-free, RoHS-compliant, and qualified to JESD 201 Class 2 for tin whisker resistance. It also specifies packaging in 7" diameter plastic tape and reel (750 units per reel), supporting automated SMT placement without moisture sensitivity concerns (MSL Level 1), eliminating pre-reflow baking requirements.
