Product details
Overview
SMBJ60AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range (VBR at 1 mA), 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMBJ60AHE3_B/H datasheet, SMBJ60AHE3_B/H pinout, SMBJ60AHE3_B/H application, or SMBJ60AHE3_B/H equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom and automotive protection systems.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its VBR threshold, limiting transient energy to protect downstream ICs and MOSFETs. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed for unidirectional operation only, SMBJ60AHE3_B/H exhibits 1.0 µA max reverse leakage at 60 V, 0.105 %/°C temperature coefficient of VBR, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - enabling robust automated SMT assembly in high-reliability automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 96.8 V at 6.2 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines system overvoltage margin. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capability for standardized 10/1000 µs surge; supports IEC 61000-4-5 Level 4 immunity. |
| IPPM (Peak Pulse Current) | 6.2 A - Maximum non-repetitive surge current it can shunt without failure; sets minimum series impedance requirements. |
| TJmax | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Package | SMB (DO-214AA) - Industry-standard 2-pin surface-mount outline with 5.0 mm × 3.9 mm footprint and 2.2 mm height; compatible with standard pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, cathode indicated by band marking on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; completes clamping loop during transient events. |
| Cathode | Reverse-biased terminal / Clamping node | Connected to protected line (e.g., 12 V rail); avalanche conduction initiates here when VWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for powertrain and body control modules. |
| 600 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 4 kV/2 Ω combination wave testing without derating in typical PCB layouts. |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA) across temperature and lifetime - critical for low-power sensor nodes. |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without moisture sensitivity concerns - eliminates bake requirements in production. |
| Low RθJL = 20 °C/W | Facilitates efficient heat transfer to PCB copper pads, sustaining repetitive surge duty cycles in compact designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-E3/52 | Commercial-grade (non-AEC-Q101), same electrical specs and SMB package. | Lacks automotive qualification; suitable for consumer/industrial use where AEC-Q101 not mandated. | Select SMBJ60AHE3_B/H when automotive qualification, traceable lot control, and extended temperature validation are required. |
| SMCJ60AHE3_A/H | Same AEC-Q101 rating but in larger SMC (DO-214AB) package with 1500 W PPPM. | Higher power handling requires larger PCB area; used where higher surge immunity (e.g., ISO 16750-2) is needed. | Choose SMBJ60AHE3_B/H for space-constrained designs needing 600 W rating and AEC-Q101 compliance in minimal footprint. |
Compared with SMBJ60A-E3/52, SMBJ60AHE3_B/H adds AEC-Q101 qualification and enhanced process controls for automotive use; compared with SMCJ60AHE3_A/H, it trades 2.5× lower surge power for 40 % smaller board area and identical qualification level.

FAQ
What is the clamping voltage of SMBJ60AHE3_B/H at its rated peak pulse current?
The SMBJ60AHE3_B/H has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ60AHE3_B/H maintains this clamping performance across its qualified temperature range and after multiple surge cycles when mounted per recommended pad layout.
Is SMBJ60AHE3_B/H suitable for bidirectional transient protection?
No, SMBJ60AHE3_B/H is a unidirectional TVS diode, intended for DC-biased lines where polarity is fixed - such as automotive 12 V rails or regulated power outputs. For bidirectional protection (e.g., AC lines or data buses), Vishay offers the SMBJ60CA variant. The SMBJ60AHE3_B/H cathode band marking confirms its unidirectional orientation, and reverse connection would result in forward conduction rather than clamping.
Does SMBJ60AHE3_B/H meet automotive qualification standards?
Yes, SMBJ60AHE3_B/H is AEC-Q101 qualified, verified per the full stress test suite including HTGB, HTRB, TCT, and surge endurance. Its HE3 suffix explicitly denotes AEC-Q101 compliance, RoHS conformity, and automotive-grade material content. This makes SMBJ60AHE3_B/H appropriate for use in engine control units, ADAS modules, and body electronics where automotive reliability is mandatory.
What is the thermal resistance from junction to lead (RθJL) for SMBJ60AHE3_B/H?
The SMBJ60AHE3_B/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard mounting conditions. This low value enables effective heat dissipation into PCB copper pads during repetitive surge events. When designing layouts, using ≥5.0 mm × 5.0 mm copper pads per terminal - as specified in the Vishay datasheet - ensures SMBJ60AHE3_B/H remains within its 150 °C maximum junction temperature limit.
How does the VBR tolerance of SMBJ60AHE3_B/H affect circuit design margin?
SMBJ60AHE3_B/H specifies a breakdown voltage (VBR) range of 66.7 V to 73.7 V at 1 mA test current, representing ±5 % tolerance around the nominal 70.2 V midpoint. Designers must ensure the protected circuit's absolute maximum voltage rating exceeds 73.7 V to avoid unintended clamping during normal operation. This tolerance directly impacts the margin between VWM (60 V) and VBR, and informs selection of upstream overvoltage protection thresholds.
